It was necessary to find what could be deemed as a “comfortable” deceleration so that passengers do not feel as if they are suddenly jerked and pressed against the restraining harnesses. A human factors engineering approach was taken in order to determine this deceleration. Using a previous study that tested the deceleration of transit vehicles, it was found that a -0.45 G deceleration would be used as a design requirement to build this system around. An adjustable linear eddy current brake using permanent magnets would be the ideal system to use in order to meet this design requirement. Anthropometric data were then used to determine a realistic weight and length of the roller coaster that the brake was being designed for. The weight and length data were then factored into magnetic brake force equations. These equations were used to determine how the brake system and the brake run layout would be designed. A final design for the brake was determined and it was found that a total of 12 brakes would be needed with a maximum braking distance of 53.6 m in order to stop a roller coaster travelling at its top speed and loaded to maximum capacity. This design is derived from theoretical calculations, but is within the realm of feasibility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eddy%20current%20brake" title="eddy current brake">eddy current brake</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering%20design" title=" engineering design"> engineering design</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20synthesis" title=" design synthesis"> design synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20factors%20engineering" title=" human factors engineering"> human factors engineering</a> </p> <a href="https://publications.waset.org/abstracts/123650/design-of-an-eddy-current-brake-system-for-the-use-of-roller-coasters-based-on-a-human-factors-engineering-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123650.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9154</span> Equivalent Circuit Model for the Eddy Current Damping with Frequency-Dependence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhiguo%20Shi">Zhiguo Shi</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng%20Ning%20Loong"> Cheng Ning Loong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiazeng%20Shan"> Jiazeng Shan</a>, <a href="https://publications.waset.org/abstracts/search?q=Weichao%20Wu">Weichao Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study proposes an equivalent circuit model to simulate the eddy current damping force with shaking table tests and finite element modeling.

Then, a non-contact and friction-free eddy current damper is designed and tested, and the proposed model can reproduce the experimental observations. The excellent agreement between the simulated results and the experimental data validates the accuracy and reliability of the equivalent circuit model. Furthermore, a more complicated model is performed in ANSYS to verify the feasibility of the equivalent circuit model in complex eddy current damper, and the higher-order fractional model and viscous model are adopted for comparison. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=equivalent%20circuit%20model" title="equivalent circuit model">equivalent circuit model</a>, <a href="https://publications.waset.org/abstracts/search?q=eddy%20current%20damping" title=" eddy current damping"> eddy current damping</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20model" title=" finite element model"> finite element model</a>, <a href="https://publications.waset.org/abstracts/search?q=shake%20table%20test" title=" shake table test"> shake table test</a> </p> <a href="https://publications.waset.org/abstracts/119732/equivalent-circuit-model-for-the-eddy-current-damping-with-frequency-dependence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119732.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">191</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9153</span> Development of Detachable Brake System for Moving Apparatus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bong-Keun%20Jung">Bong-Keun Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung-Yeon%20Kim"> Jung-Yeon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to investigate usability of detachable brake system for moving apparatus such as baby strollers, manual wheelchairs or walkers.

The finite element method is used for describing the eddy current technique in a mathematical model by the prediction of the eddy current interaction with defects.

In this study, the analysis of the problem is based on a three dimensional finite element model that computes directly the electromagnetic field distortions due to defects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eddy%20current" title="eddy current">eddy current</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=non%20destructive%20testing" title=" non destructive testing"> non destructive testing</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulations" title=" numerical simulations"> numerical simulations</a> </p> <a href="https://publications.waset.org/abstracts/7187/modeling-and-simulation-for-3d-eddy-current-testing-in-conducting-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7187.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">443</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9151</span> An Experimental Study of Automotive Drum Brake Vibrations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nouby%20Ghazaly">Nouby Ghazaly</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper investigates experimentally the effect coefficient of friction at different operation conditions on the variation of the brake temperature, brake force, and brake vibration with the braking time. All the experimental tests were carried out using brake dynamometer which designed and constructed in Vehicle Dynamic Laboratory. The results indicate that the brake temperature increases with the increase of the normal force and sliding speed especially with the increase of the braking time. The normal force has the effect on increasing the brake force. On the contrary, the vehicle speed has the effect on decreasing the brake force.

The core function of these devices is a brake actuator. The goal of this study is to design and control a magnetorheological brake which can be used as a rehabilitation tool. In fact, the fluid used in this brake is called magnetorheological fluid or MR that properties can change by variation of the magnetic field. The braking properties can be set as control by using this feature of the fluid. In this research, different MR brake designs are first introduced in each design, and the dimensions of the brake have been determined based on the required torque for foot movement. To calculate the brake dimensions, it is assumed that the shear stress distribution in the fluid is uniform and the fluid is in its saturated state. After designing the rehabilitation brake, the mathematical model of the healthy movement of a healthy person is extracted. Due to the nonlinear nature of the system and its variability, various adaptive controllers, neural networks, and robust have been implemented to estimate the parameters and control the system. After calculating torque and control current, the best type of controller in terms of error and control current has been selected. Finally, this controller is implemented on the experimental data of the patient's movements, and the control current is calculated to achieve the desired torque and motion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title="rehabilitation">rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetorheological%20fluid" title=" magnetorheological fluid"> magnetorheological fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=knee" title=" knee"> knee</a>, <a href="https://publications.waset.org/abstracts/search?q=brake" title=" brake"> brake</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20control" title=" adaptive control"> adaptive control</a>, <a href="https://publications.waset.org/abstracts/search?q=robust%20control" title=" robust control"> robust control</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network%20control" title=" neural network control"> neural network control</a>, <a href="https://publications.waset.org/abstracts/search?q=torque%20control" title=" torque control"> torque control</a> </p> <a href="https://publications.waset.org/abstracts/134338/design-and-control-of-a-knee-rehabilitation-device-using-an-mr-fluid-brake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134338.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9149</span> Effect of Compressibility of Brake Friction Materials on Vibration Occurrence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Makrahy">Mostafa Makrahy</a>, <a href="https://publications.waset.org/abstracts/search?q=Nouby%20Ghazaly"> Nouby Ghazaly</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Moaaz"> Ahmad Moaaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brakes are one of the most important safety and performance components in automobiles and airplanes. Development of brakes has mainly focused on increasing braking power and stability. Nowadays, brake noise, vibration and harshness (NVH) together with brake dust emission and pad life are very important to vehicle drivers. The main objective of this research is to define the relationship between compressibility of friction materials and their tendency to generate vibration. An experimental study of the friction-induced vibration obtained by the disc brake system of a passenger car is conducted. Three commercial brake pad materials from different manufacturers are tested and evaluated under various brake conditions against cast iron disc brake. First of all, compressibility test for the brake friction material are measured for each pad. Then, brake dynamometer is used to simulate and reproduce actual vehicle braking conditions. Finally, a comparison between the three pad specimens is conducted. The results showed that compressibility have a very significant effect on reduction the vibration occurrence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automotive%20brake" title="automotive brake">automotive brake</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20material" title=" friction material"> friction material</a>, <a href="https://publications.waset.org/abstracts/search?q=brake%20dynamometer" title=" brake dynamometer"> brake dynamometer</a>, <a href="https://publications.waset.org/abstracts/search?q=compressibility%20test" title=" compressibility test"> compressibility test</a> </p> <a href="https://publications.waset.org/abstracts/78445/effect-of-compressibility-of-brake-friction-materials-on-vibration-occurrence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78445.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">237</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9148</span> A New Car-Following Model with Consideration of the Brake Light</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhiyuan%20Tang">Zhiyuan Tang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ju%20Zhang"> Ju Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenyuan%20Wu"> Wenyuan Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, a car-following model with consideration of the status of the brake light is proposed.

The brake squeal produces an audible sound at high frequency that is irritating to the human ear. To study this critical problem, first a nonlinear mathematical model with three degree of freedom is developed. This model consists of a point mass that simulates the brake pad and a sliding surface that simulates the brake rotor. The model exposes kinematic and clearance nonlinearities, but no friction nonlinearity. In the formulation, the friction coefficient is assumed to be constant and the friction force does not change direction. The nonlinear governing equations of the model are first obtained, and numerical solutions are sought for different cases. Second, a computational model for the squeal problem is developed with a commercial software, and computational solutions are obtained with two different types of contact cases (solid-to-solid and sphere-to-plane). This model consists of three rigid bodies and several elastic elements that simulate the key characteristics of a brake system. The response obtained from this model is compared with numerical solutions in time and frequency domain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contact%20force" title="contact force">contact force</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinearities" title=" nonlinearities"> nonlinearities</a>, <a href="https://publications.waset.org/abstracts/search?q=brake%20squeal" title=" brake squeal"> brake squeal</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20brake" title=" vehicle brake"> vehicle brake</a> </p> <a href="https://publications.waset.org/abstracts/52950/dynamic-investigation-of-brake-squeal-problem-in-the-presence-of-kinematic-nonlinearities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52950.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">246</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9143</span> Comparative Assessment of ABS and Disk Brake Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saleh%20Mobasseri">Saleh Mobasseri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mobasseri"> Mohammad Mobasseri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The article refers to the history of the rise of brake system and described it’s importance in passenger’s lives.

In case of emergency, both braking distance and stopping time are longer than the usual situation. Therefore, the passenger safety and the HST driving control management are definitely obtained by reducing the time and distance of train braking during emergency situation. Due to the limited study and implementation of the aerodynamic brake in HST, the possibility in use and the effectiveness of the aerodynamic brake to the train dynamic movement during braking are analyzed and considered. Regarding the aircraft’s flaps that applied in the HST, the areas of the aerodynamic brake acted as an additional drag force during train braking are able to vary depending on the operating angle and the required dynamic braking force. The HST with a varying speed of 200 km/h to 350 km/h is taken as a case study of this paper. The results show that the stopping time and the brake distance are effectively reduced by the aerodynamic brakes. The mechanical brake and its maintenance are effectively getting this benefit by extending its lifetime for longer use. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-speed%20train" title="high-speed train">high-speed train</a>, <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20brake" title=" aerodynamic brake"> aerodynamic brake</a>, <a href="https://publications.waset.org/abstracts/search?q=brake%20distance" title=" brake distance"> brake distance</a>, <a href="https://publications.waset.org/abstracts/search?q=drag%20force" title=" drag force "> drag force </a> </p> <a href="https://publications.waset.org/abstracts/122559/aerodynamic-brake-study-of-reducing-braking-distance-for-high-speed-trains" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122559.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">198</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9139</span> Application of Exhaust Gas-Air Brake System in Petrol and Diesel Engine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurlal%20Singh">Gurlal Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Rupinder%20Singh"> Rupinder Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The possible role of the engine brake is to convert a power-producing engine into a power-absorbing retarding mechanism. In this braking system, exhaust gas (EG) from the internal combustion (IC) engines is used to operate air brake in the automobiles. Airbrake is most used braking system in vehicles. In the proposed model, instead of air brake, EG is used to operate the brake lever and stored in a specially designed tank. This pressure of EG is used to operate the pneumatic cylinder and brake lever. Filters used to remove the impurities from the EG, then it is allowed to store in the tank. Pressure relief valve is used to achieve a specific pressure in the tank and helps to avoid further damage to the tank as well as in an engine. The petrol engine is used in the proposed EG braking system. The petrol engine is chosen initially because it produces less impurity in the exhaust than diesel engines. Moreover, exhaust brake system (EBS) for the Diesel engines is composed of gate valve, pneumatic cylinder and exhaust brake valve with the on-off solenoid. Exhaust brake valve which is core component of EBS should have characteristics such as high reliability and long life. In a diesel engine, there is butterfly valve in exhaust manifold connected with solenoid switch which is used to on and off the butterfly valve. When butterfly valve closed partially, then the pressure starts built up inside the exhaust manifold and cylinder that actually resist the movement of piston leads to crankshaft getting stops resulting stopping of the flywheel. It creates breaking effect in a diesel engine. The exhaust brake is a supplementary breaking system to the service brake. It is noted that exhaust brake increased 2-3 fold the life of service brake may be due to the creation of negative torque which retards the speed of the engine. More study may also be warranted for the best suitable design of exhaust brake in a diesel engine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exhaust%20gas" title="exhaust gas">exhaust gas</a>, <a href="https://publications.waset.org/abstracts/search?q=automobiles" title=" automobiles"> automobiles</a>, <a href="https://publications.waset.org/abstracts/search?q=solenoid" title=" solenoid"> solenoid</a>, <a href="https://publications.waset.org/abstracts/search?q=airbrake" title=" airbrake"> airbrake</a> </p> <a href="https://publications.waset.org/abstracts/93446/application-of-exhaust-gas-air-brake-system-in-petrol-and-diesel-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93446.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">260</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9138</span> Lattice Network Model for Calculation of Eddy Current Losses in a Solid Permanent Magnet</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jan%20Schmidt">Jan Schmidt</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre%20K%C3%B6hring"> Pierre Köhring</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Permanently excited machines are set up with magnets that are made of highly energetic magnetic materials. Inherently, the permanent magnets warm up while the machine is operating. With an increasing temperature, the electromotive force and hence the degree of efficiency decrease. The reasons for this are slot harmonics and distorted armature currents arising from frequency inverter operation. To prevent or avoid demagnetizing of the permanent magnets it is necessary to ensure that the magnets do not excessively heat up. Demagnetizations of permanent magnets are irreversible and a breakdown of the electrical machine is inevitable. For the design of an electrical machine, the knowledge of the behavior of heating under operating conditions of the permanent magnet is of crucial importance. Therefore, a calculation model is presented with which the machine designer can easily calculate the eddy current losses in the magnetic material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20model" title="analytical model">analytical model</a>, <a href="https://publications.waset.org/abstracts/search?q=eddy%20current" title=" eddy current"> eddy current</a>, <a href="https://publications.waset.org/abstracts/search?q=losses" title=" losses"> losses</a>, <a href="https://publications.waset.org/abstracts/search?q=lattice%20network" title=" lattice network"> lattice network</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet" title=" permanent magnet"> permanent magnet</a> </p> <a href="https://publications.waset.org/abstracts/38170/lattice-network-model-for-calculation-of-eddy-current-losses-in-a-solid-permanent-magnet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38170.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">420</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9137</span> Optimization Principles of Eddy Current Separator for Mixtures with Different Particle Sizes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cao%20Bin">Cao Bin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuan%20Yi"> Yuan Yi</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Qiang"> Wang Qiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Amor%20Abdelkader"> Amor Abdelkader</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Reza%20Kamali"> Ali Reza Kamali</a>, <a href="https://publications.waset.org/abstracts/search?q=Diogo%20Montalv%C3%A3o"> Diogo Montalvão</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study of the electrodynamic behavior of non-ferrous particles in time-varying magnetic fields is a promising area of research with wide applications, including recycling of non-ferrous metals, mechanical transmission, and space debris. The key technology for recovering non-ferrous metals is eddy current separation (ECS), which utilizes the eddy current force and torque to separate non-ferrous metals. ECS has several advantages, such as low energy consumption, large processing capacity, and no secondary pollution, making it suitable for processing various mixtures like electronic scrap, auto shredder residue, aluminum scrap, and incineration bottom ash. Improving the separation efficiency of mixtures with different particle sizes in ECS can create significant social and economic benefits. Our previous study investigated the influence of particle size on separation efficiency by combining numerical simulations and separation experiments. Pearson correlation analysis found a strong correlation between the eddy current force in simulations and the repulsion distance in experiments, which confirmed the effectiveness of our simulation model. The interaction effects between particle size and material type, rotational speed, and magnetic pole arrangement were examined. It offer valuable insights for the design and optimization of eddy current separators. The underlying mechanism behind the effect of particle size on separation efficiency was discovered by analyzing eddy current and field gradient. The results showed that the magnitude and distribution heterogeneity of eddy current and magnetic field gradient increased with particle size in eddy current separation. Based on this, we further found that increasing the curvature of magnetic field lines within particles could also increase the eddy current force, providing a optimized method to improving the separation efficiency of fine particles. By combining the results of the studies, a more systematic and comprehensive set of optimization guidelines can be proposed for mixtures with different particle size ranges. The separation efficiency of fine particles could be improved by increasing the rotational speed, curvature of magnetic field lines, and electrical conductivity/density of materials, as well as utilizing the eddy current torque. When designing an ECS, the particle size range of the target mixture should be investigated in advance, and the suitable parameters for separating the mixture can be fixed accordingly. In summary, these results can guide the design and optimization of ECS, and also expand the application areas for ECS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eddy%20current%20separation" title="eddy current separation">eddy current separation</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20size" title=" particle size"> particle size</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20recovery" title=" metal recovery"> metal recovery</a> </p> <a href="https://publications.waset.org/abstracts/164756/optimization-principles-of-eddy-current-separator-for-mixtures-with-different-particle-sizes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164756.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9136</span> Study on the Retaining Sleeve Structure for the Reduction of Eddy Current in SPMSM</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyun-Woo%20Jun">Hyun-Woo Jun</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Gun%20Kim"> In-Gun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Seok%20Hong"> Hyun Seok Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong-Woo%20Kang"> Dong-Woo Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ju%20Lee"> Ju Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In high-speed SPMSM design, the rotor-retaining sleeve is inserted into rotor to prevent permanent magnet’s damage.

The water brake mechanism is used for dynamic systems such as sled system on rail. For the achievement of these system tests, structure-flow interaction should be investigated in detail. This study is about a sled test of an aircraft subsystem which rises to supersonic speeds thanks to rocket engines. To decrease or to stop the thrusting rocket sleds, water brake mechanisms are used. Water brake mechanism provides the deceleration of the structures that have supersonic speeds. Therefore, structure-flow interaction may cause damage to the water brake mechanism. To verify all design revisions with system tests are so costly so that some decisions are taken in accordance with numerical methods. In this study, structure-flow interaction that belongs to water brake mechanism is solved with Abaqus CEL approach. Fluid and deformation on the structure behaviors are modeled at the same time thanks to CEL approach. Provided analysis results are corrected with the dynamic tests. Deformation zones seen in numerical analysis are also observed in dynamic tests. Finally, Johnson-Cook material model parameters used for this analysis are proven, and it is understood that these parameters can be used for dynamic analysis like water brake mechanism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aircraft" title="aircraft">aircraft</a>, <a href="https://publications.waset.org/abstracts/search?q=rocket" title=" rocket"> rocket</a>, <a href="https://publications.waset.org/abstracts/search?q=structure-flow" title=" structure-flow"> structure-flow</a>, <a href="https://publications.waset.org/abstracts/search?q=supersonic" title=" supersonic"> supersonic</a> </p> <a href="https://publications.waset.org/abstracts/104502/analysis-of-structure-flow-interaction-for-water-brake-mechanism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104502.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9134</span> Effects of Humidity and Silica Sand Particles on Vibration Generation by Friction Materials of Automotive Brake System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20M.%20Makrahy">Mostafa M.

Also, the vibration of the brake disc is examined against the friction material in humidity environment conditions under variable rotational speed. The experimental results showed that the silica sand particles have significant contribution on the value of vibration amplitude which enhances with increasing the size of silica sand particles at different speed conditions. Also, it is noticed that the friction material is sensitive to humidity and the vibration magnitude increases under wet testing conditions.

Use of asbestos fibre can cause health risks. The goal of this study is to determine the effect of ecological brake pad samples which are produced under different compaction pressure values and mixture ratios by using miscanthus as reinforcement component on the density, hardness, wear rate and compression strength properties, and friction coefficients changes of ecological brake pad samples. Miscanthus powder, cashew powder, alumina powder, phenolic resin powder, and calcite powder mixtures were used to produce ecological brake pad samples. The physical properties of the brake pad samples produced under different mixture ratios and compaction pressures values were determined to assign their effects on them by using Taguchi experimental design. Mixture ratios and compaction pressures values were chosen as the factors with three-levels. Experiments are conducted to L₉(3⁴) Taguchi orthogonal array design. The results showed that hardness value is very much affected both compaction pressure values and mixture ratios than the other physical properties. When reinforcing component ratio within the mixture and compaction pressure value is increased, hardness and compression strength values of the all samples are also increased. All test results taking into account, the ideal compaction value for used components and mixture ratios were determined as 200 MPa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brake%20pad" title="brake pad">brake pad</a>, <a href="https://publications.waset.org/abstracts/search?q=eco-friendly%20materials" title=" eco-friendly materials"> eco-friendly materials</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness" title=" hardness"> hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=Miscanthus" title=" Miscanthus"> Miscanthus</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title=" Taguchi method"> Taguchi method</a> </p> <a href="https://publications.waset.org/abstracts/52015/investigation-of-effect-of-mixture-ratio-and-compaction-pressure-of-reinforced-with-miscanthus-fibre-brake-pad-samples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52015.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">327</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9129</span> Study of Engine Performance and Exhaust Emissions on Multi-Cylinder Turbo-Charged Diesel Engine Operated with B5 Biodiesel Blend </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pradip%20Lingfa">Pradip Lingfa</a>, <a href="https://publications.waset.org/abstracts/search?q=L.%20M.%20Das"> L.

This situation resulted in a search for an alternative fuel. Non-edible vegetable oils are promising sources for producing liquid fuels. In the present experimental investigation, the engine tests were carried out for performance and exhaust emissions on 2.5 L Turbo-charged diesel engine fuelled with 5% biodiesel blend obtained from non-edible vegetable oils such as Jatropha, Karanja, and Castor Seeds. The engine tests were carried out at full throttle position with various engine speeds of 1500, 1750, 2000, 2250, 2750 and 3000 rpm respectively. After test, it was observed that 5% Jatropha biodiesel blend have highest brake power of 46.65 kW and less brake specific fuel consumptions of 225.8 kg/kW-hr compared to other two biodiesel blends of brake power of 45.99 kW, 45.81 kW and brake specific fuel consumption of 234.34, 236.55 kg/kW-hr respectively. The brake specific fuel consumption of biodiesel blends increase at increasing speeds for all biodiesel blends. NOx emissions for biodiesel blends were observed to be higher compared to diesel fuel during the entire range of engine operations.

The share of electric vehicles in the sale of new cars increases every year. However, their performance and, above all, range cannot be today successfully compared to those of cars with a traditional internal combustion engine. Battery recharging lasts hours, which can be hardly accepted due to the time needed to refill a fuel tank. Therefore, the ways to reduce the adverse features of cars equipped with electric motors only are searched for. One of the methods is a combination of an electric engine as a main source of power and a small internal combustion engine as an electricity generator. This type of drive enables an electric vehicle to achieve a radically increased range and low emissions of toxic substances. For several years, the leading automotive manufacturers like the Mazda and the Audi together with the best companies in the automotive industry, e.g., AVL have developed some electric drive systems capable of recharging themselves while driving, known as a range extender. An electricity generator is powered by a Wankel engine that has seemed to pass into history. This low weight and small engine with a rotating piston and a very low vibration level turned out to be an excellent source in such applications. Its operation as an energy source for a generator almost entirely eliminates its disadvantages like high fuel consumption, high emission of toxic substances, or short lifetime typical of its traditional application. The operation of the engine at a constant rotational speed enables a significant increase in its lifetime, and its small external dimensions enable us to make compact modules to drive even small urban cars like the Audi A1 or the Mazda 2. The algorithm to maintain a constant speed was investigated on the engine dynamometer with an eddy current brake and the necessary measuring apparatus. The research object was the Aixro XR50 rotary engine with the electronic power supply developed at the Lublin University of Technology. The load torque of the engine was altered during the research by means of the eddy current brake capable of giving any number of load cycles. The parameters recorded included speed and torque as well as a position of a throttle in an inlet system. Increasing and decreasing load did not significantly change engine speed, which means that control algorithm parameters are correctly selected. This work has been financed by the Polish Ministry of Science and Higher Education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicle" title="electric vehicle">electric vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20generator" title=" power generator"> power generator</a>, <a href="https://publications.waset.org/abstracts/search?q=range%20extender" title=" range extender"> range extender</a>, <a href="https://publications.waset.org/abstracts/search?q=Wankel%20engine" title=" Wankel engine"> Wankel engine</a> </p> <a href="https://publications.waset.org/abstracts/81482/investigating-the-algorithm-to-maintain-a-constant-speed-in-the-wankel-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81482.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9127</span> Effect of Eddy Irrigant Activation on Cleanliness of the Root Canal Wall during Pulpectomy of Primary Teeth </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rasha%20Sharaf">Rasha Sharaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Nehal%20Sharaf"> Nehal Sharaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pulpectomy of primary teeth aims to remove the necrotic pulp tissue from the infected root canal and clean the root canal walls from any remnant of pulp tissue. Different irrigant activation systems have been recently used, and one of these devices is the Eddy which helps in removal of smear layer and improves the intimate contact between the filling material and the root canal wall. Aim: To evaluate the efficacy of Eddy in cleanliness of the root canal during pulpectomy of primary teeth. Materials and methods: 45 freshly extracted primary anterior teeth were divided into 3 equal groups, in the 1st group sodium hypochlorite only was used during pulpectomy, in the 2nd group irrigation using sodium hypochlorite with file agitation was performed and in the 3rd group sodium hypochlorite was used with Eddy for irrigant activation. All samples were sectioned longitudinally and scanned using scanning electron microscope to evaluate the cleanliness of the root canals. Results: It was found that Eddy showed high efficacy in removal of smear layer during pulpectomy of primary teeth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eddy" title="Eddy">Eddy</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigant%20activation" title=" irrigant activation"> irrigant activation</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigation" title=" irrigation"> irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=pulpectomy" title=" pulpectomy"> pulpectomy</a> </p> <a href="https://publications.waset.org/abstracts/131150/effect-of-eddy-irrigant-activation-on-cleanliness-of-the-root-canal-wall-during-pulpectomy-of-primary-teeth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131150.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9126</span> The Effect of Volume Fraction of Nano-Alumina Strengthening on AC4B Composite Characteristics through the Stir Casting Method as a Material Brake Shoe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benny%20Alexander">Benny Alexander</a>, <a href="https://publications.waset.org/abstracts/search?q=Ikhlashia%20N.%20Fadhilah"> Ikhlashia N.

Syahrial</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brake shoe is a component that serves to reduce speed or stop the train's speed by utilizing the friction force. Generally, the material used as a brake shoe is cast iron, where cast iron itself is a heavy, expensive, and easily worn material. Aluminum matrix composites are one of candidates for the cast iron replacement material as the basic material for brake shoe. The matrix in the composite used is Aluminum AC4B. Reinforcement used in aluminum matrix composites is nano-alumina, where the use of nano-alumina of 0.25%, 0.3%, 0.35%, 0.4%, and 0.5% volume fraction will be tested. The sample is made using the stir casting method; then, it will be tested mechanically. The use of nano-alumina as a reinforcement will increase the strength of the matrix. SEM (scanning electron microscopy) testing is used to test the distribution of reinforcing particles due to stirring. Therefore, the addition of nano-alumina will improve AC4B aluminum matrix composites. <p class="card-text"><strong>Keywords:</strong> <a
