In General vehicle has multiple sub-systems such as powertrain, BIW, Brakes, Actuations, Suspension and Seats etc., To withstand the market challenges, the contribution of each sub-system is very vital. The malfunction of any one sub system will directly have an impact on the performance of the major system which lead to dis-satisfaction to the end user. The Powertrain system consists of several sub-systems in which clutch is one of the prime sub-systems in MT vehicles which assist for smoother gear shifts with proper clutch dis-engagement and engagement. In general, most of the vehicles will have a mechanical or semi or full hydraulic clutch release system, whereas in small Commercial Vehicles (SCV) the majorly used clutch release system is mechanical cable release system due to its lesser cost and functional requirements. The major bottle neck in the cable type clutch release system is increase in pedal effort due to hysteresis increase and Gear shifting hard due to efficiency loss / cable slackness over the mileage accumulation of the vehicle. This study is to mainly focus on how the efficiency and hysteresis change over the mileage of the vehicle occurs because of the design architecture of outer and inner cable. The study involves several cable design validation results from vehicle level and rig level through the defined cable routing and test procedures. Results are compared to evaluate the suitable cable design architecture based on better efficiency and lower hysteresis parameters at initial and end of the validation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clutch" title="clutch">clutch</a>, <a href="https://publications.waset.org/abstracts/search?q=clutch%20cable" title=" clutch cable"> clutch cable</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=architecture" title=" architecture"> architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=cable%20routing" title=" cable routing"> cable routing</a> </p> <a href="https://publications.waset.org/abstracts/157322/study-of-clutch-cable-architecture-and-its-influence-in-efficiency-of-mechanical-cable-release-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157322.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">118</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">178</span> Effect of Sedimentation on Torque Transmission in the Larger Radius Magnetorheological Clutch</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manish%20Kumar%20Thakur">Manish Kumar Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiranjit%20Sarkar"> Chiranjit Sarkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sedimentation of magnetorheological (MR) fluid affects its working. MR fluid is a smart fluid that has unique qualities such as quick responsiveness and easy controllability. It is used in the MR damper, MR brake, and MR clutch. In this work effect of sedimentation on torque transmission in the shear mode operated MR clutch is investigated. A test rig is developed to test the impact of sedimentation on torque transmission in the MR clutch. Torque transmission capability of MR clutch has been measured under two conditions to confirm the result of sedimentation. The first experiment is done just after filling and the other after one week. It has been observed that transmission torque is decreased after sedimentation. Hence sedimentation affects the working of the MR clutch. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clutch" title="clutch">clutch</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=sedimentation" title=" sedimentation"> sedimentation</a>, <a href="https://publications.waset.org/abstracts/search?q=torque" title=" torque"> torque</a> </p> <a href="https://publications.waset.org/abstracts/133283/effect-of-sedimentation-on-torque-transmission-in-the-larger-radius-magnetorheological-clutch" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133283.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">184</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">177</span> Online Estimation of Clutch Drag Torque in Wet Dual Clutch Transmission Based on Recursive Least Squares</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hongkui%20Li">Hongkui Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Tongli%20Lu"> Tongli Lu </a>, <a href="https://publications.waset.org/abstracts/search?q=Jianwu%20Zhang"> Jianwu Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper focuses on developing an estimation method of clutch drag torque in wet DCT.

Hydraulic multi-disk clutches are the key components of DCT, its engagement determines the shifting comfort. The prefill of the clutches requests an initial engagement which the clutches just contact against each other but not transmit substantial torque from the engine, this initial clutch engagement point is called the touch point. Open-loop control is typically implemented for the clutch prefill, a lot of uncertainties, such as oil temperature and clutch wear, significantly affects the prefill, probably resulting in an inappropriate touch point. Underfill causes the engine flaring in gearshift while overfill arises clutch tying up, both deteriorating the shifting comfort of DCT. Therefore, it is important to enable an adaptive capacity for the clutch prefills regarding the uncertainties. In this paper, a dynamic model of the hydraulic actuator system is presented, including the variable force solenoid and clutch piston, and validated by a test. Subsequently, the open-loop clutch prefill is simulated based on the proposed model. Two control parameters of the prefill, fast fill time and stable fill pressure is analyzed with regard to the impact on the prefill. The former has great effects on the pressure transients, the latter directly influences the touch point. Finally, an adaptive method is proposed for the clutch prefill during gear shifting, in which clutch fill control parameters are adjusted adaptively and continually. The adaptive strategy is changing the stable fill pressure according to the current clutch slip during a gearshift, improving the next prefill process. The stable fill pressure is increased by means of the clutch slip while underfill and decreased with a constant value for overfill. The entire strategy is designed in the Simulink/Stateflow, and implemented in the transmission control unit with optimization. Road vehicle test results have shown the strategy realized its adaptive capability and proven it improves the shifting comfort. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clutch%20prefill" title="clutch prefill">clutch prefill</a>, <a href="https://publications.waset.org/abstracts/search?q=clutch%20slip" title=" clutch slip"> clutch slip</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20clutch%20transmission" title=" dual clutch transmission"> dual clutch transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=touch%20point" title=" touch point"> touch point</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20force%20solenoid" title=" variable force solenoid"> variable force solenoid</a> </p> <a href="https://publications.waset.org/abstracts/52302/dynamic-analysis-and-clutch-adaptive-prefill-in-dual-clutch-transmission" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52302.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">308</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">175</span> Detect Cable Force of Cable Stayed Bridge from Accelerometer Data of SHM as Real Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Lan">Nguyen Lan</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Tan%20Kien"> Le Tan Kien</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Pham%20Gia%20Bao"> Nguyen Pham Gia Bao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cable-stayed bridge belongs to the combined system, in which the cables is a major strutual element.

Cables tension monitoring is a structural monitoring content. It is common to measure cable tension by a direct force sensor or cable vibration accelerometer sensor, thereby inferring the indirect cable tension through the cable vibration frequency. To translate cable-stayed vibration acceleration data to real-time tension requires some necessary calculations and programming.

In agricultural tractors, friction clutches are widely used in power transmission applications. To transmit the maximum torque in friction clutches, selection of materials is one of the important tasks. The present used material for friction disc is Asbestos, Ceramic etc. In this study, analysis is performed using composites materials. The composite materials are considered due to their high strength to weight ratio. Composite materials like kevlar49, kevlar 29U were used in the study. The paper presents a systematic approach to optimize the structural and thermal characteristics of the clutch friction pad. A single plate clutch is modeled using Creo 2.0 software and analyzed using ANSYS. Thermal analysis considers the reduction of heat generated between the friction surfaces and reducing the temperature rise during the steady state period. Structural analysis is done to minimize the stresses developed as a result of the loading contact between friction surfaces. Also, modal analysis is done to optimize the natural frequency of the friction plate to avoid being in resonance with the engine frequency range. The analysis carried out on ANSYS workbench to get the foremost appropriate friction material for clutch. From the analyzed results stress, strain / total deformation values and natural frequency of the materials were compared for all the composite materials and the best one was taken out. For the study purpose, specifications of the clutch are obtained from the MF1035 (47KW) Tractor model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANSYS" title="ANSYS">ANSYS</a>, <a href="https://publications.waset.org/abstracts/search?q=clutch" title=" clutch"> clutch</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20materials" title=" composite materials"> composite materials</a>, <a href="https://publications.waset.org/abstracts/search?q=creo" title=" creo"> creo</a> </p> <a href="https://publications.waset.org/abstracts/54606/numerical-and-simulation-analysis-of-composite-friction-materials-using-single-plate-clutch-pad-in-agricultural-tractors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54606.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">299</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">171</span> A Case Study on Tension Drop of Cable-band Bolts in Suspension Bridge</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sihyun%20Park">Sihyun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyunwoo%20Kim"> Hyunwoo Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Wooyoung%20Jung"> Wooyoung Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Dongwoo%20You"> Dongwoo You</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Regular maintenance works are very important on the axial forces of the cable-band bolts in suspension bridges.

As a result, the main cause of reduction in the cable-band bolt axial force was confirmed by the plastic deformation of the zinc plating layer used in the main cable wire, and thus, the theoretical process was established for the practical use in the field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cable-band%20Bolts" title="cable-band Bolts">cable-band Bolts</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20test" title=" field test"> field test</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20reduction" title=" stress reduction"> stress reduction</a> </p> <a href="https://publications.waset.org/abstracts/36196/a-case-study-on-tension-drop-of-cable-band-bolts-in-suspension-bridge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36196.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">332</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">170</span> Finite Element Method for Calculating Temperature Field of Main Cable of Suspension Bridge</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heng%20Han">Heng Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhilei%20Liang"> Zhilei Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiangong%20Zhou"> Xiangong Zhou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the finite element method is used to study the temperature field of the main cable of the suspension bridge, and the calculation method of the average temperature of the cross-section of the main cable suitable for the construction control of the cable system is proposed; By comparing and analyzing the temperature field of the main cable with five diameters, a reasonable diameter limit for calculating the average temperature of the cross section of the main cable by finite element method is proposed.

To do so, the temperature variation of the wet multi-plate clutch is investigated firstly by establishing a thermal resistance model for the gearbox cooling system. To calculate the generated heat flux and predict the clutch temperature precisely, the friction torque model is optimized by introducing an improved friction coefficient, which is related to the pressure, the relative speed and the temperature. After that, the heat transfer model and the reasonable friction torque model are employed by the vehicle powertrain model to construct a comprehensive co-simulation model for the Direct Shift Gearbox (DSG) vehicle. A creeping control strategy is then proposed and, to evaluate the vehicle performance, the safety temperature (250 ℃) is particularly adopted as an important metric. During the creeping process, the temperature of two clutches is always under the safety value (250 ℃), which demonstrates the effectiveness of the proposed control strategy in avoiding the thermal failures of clutches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creeping%20control%20strategy" title="creeping control strategy">creeping control strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20shift%20gearbox" title=" direct shift gearbox"> direct shift gearbox</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20variation" title=" temperature variation"> temperature variation</a>, <a href="https://publications.waset.org/abstracts/search?q=wet%20clutch" title=" wet clutch"> wet clutch</a> </p> <a href="https://publications.waset.org/abstracts/95295/creeping-control-strategy-for-direct-shift-gearbox-based-on-the-investigation-of-temperature-variation-of-the-wet-clutch" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95295.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">133</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">167</span> O.MG- It’s a Cyber-Enabled Fraud</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Damola%20O.%20Lawal">Damola O.

Here, the O.MG Cable, an apparently harmless mobile device charger, is used in an unauthorized way to alter the content of a file (accounts record-January_Contributions.xlsx). The aim is to determine if a forensics analyst can reliably determine who has altered the target file; the O.MG Cable or the user of the machine. This work highlights some of the traces of the O.MG Cable left behind on the target computer itself, such as the Product ID (PID) and Vendor ID (ID). Also discussed is the O.MG Cable’s behavior during the experiments. We determine if a forensics analyst could identify if any evidence has been left behind by the programmable device on the target file once it has been removed from the computer to establish if the analyst would be able to link the traces left by the O.MG Cable to the file tampering. It was discovered that the forensic analyst might mistake the actions of the O.MG Cable for the computer users. Experiments carried out in this work could further the discussion as to whether an innocent user could be punished for the unauthorized changes made by a programmable device. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.MG%20cable" title="O.MG cable">O.MG cable</a>, <a href="https://publications.waset.org/abstracts/search?q=programmable%20USB" title=" programmable USB"> programmable USB</a>, <a href="https://publications.waset.org/abstracts/search?q=file%20tampering%20attack" title=" file tampering attack"> file tampering attack</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20evidence%20credibility" title=" digital evidence credibility"> digital evidence credibility</a>, <a href="https://publications.waset.org/abstracts/search?q=miscarriage%20of%20justice" title=" miscarriage of justice"> miscarriage of justice</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20fraud" title=" cyber fraud"> cyber fraud</a> </p> <a href="https://publications.waset.org/abstracts/143005/omg-its-a-cyber-enabled-fraud" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143005.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">166</span> Comparison of Finite-Element and IEC Methods for Cable Thermal Analysis under Various Operating Environments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20S.%20Baazzim">M.

In the static equilibrium state, the marine cable has a very large sag configuration. In the motion state, the marine cable is assumed to vibrate in in-plane motion with large amplitude from the static equilibrium position. The total virtual work-energy of the marine cable at the dynamic state is formulated which involves the virtual strain energy due to axial deformation, the virtual work done by effective weight, and the inertia forces. The equations of motion for the large amplitude free vibration of marine cable are obtained by taking into account the difference between the Euler’s equation in the static state and the displaced state. Based on the Galerkin finite element procedure, the linear and nonlinear stiffness matrices, and mass matrices of the marine cable are obtained and the eigenvalue problem is solved. The natural frequency spectrum and the large amplitude free vibration behavior of marine cable are presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axial%20deformation" title="axial deformation">axial deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20vibration" title=" free vibration"> free vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=Galerkin%20finite%20element%20method" title=" Galerkin finite element method"> Galerkin finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20amplitude" title=" large amplitude"> large amplitude</a>, <a href="https://publications.waset.org/abstracts/search?q=variational%20method" title=" variational method"> variational method</a> </p> <a href="https://publications.waset.org/abstracts/114132/large-amplitude-free-vibration-of-a-very-sag-marine-cable" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114132.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">254</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">164</span> Statistical Analysis of Cables in Long-Span Cable-Stayed Bridges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ceshi%20Sun">Ceshi Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Yueyu%20Zhao"> Yueyu Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Yaobing%20Zhao"> Yaobing Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhiqiang%20Wang"> Zhiqiang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian%20Peng"> Jian Peng</a>, <a href="https://publications.waset.org/abstracts/search?q=Pengxin%20Guo"> Pengxin Guo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the rapid development of transportation, there are more than 100 cable-stayed bridges with main span larger than 300 m in China.

A new relationship between the first order frequency and the length of cable was found by conducting the curve fitting. Then, based on this relationship other interesting relationships were deduced. Several probability density functions (PDFs) were used to investigate the distributions of the parameters of first order frequency, stress level and the Irvine parameter. It was found that these parameters obey the Lognormal distribution, the Weibull distribution and the generalized Pareto distribution, respectively. Scatter diagrams of the three parameters were plotted and their 95% confidence intervals were also investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cable" title="cable">cable</a>, <a href="https://publications.waset.org/abstracts/search?q=cable-stayed%20bridge" title=" cable-stayed bridge"> cable-stayed bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=long-span" title=" long-span"> long-span</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20analysis" title=" statistical analysis"> statistical analysis</a> </p> <a href="https://publications.waset.org/abstracts/12878/statistical-analysis-of-cables-in-long-span-cable-stayed-bridges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12878.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">633</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">163</span> Feasibility Assessment of High-Temperature Superconducting AC Cable Lines Implementation in Megacities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrey%20Kashcheev">Andrey Kashcheev</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Sytnikov"> Victor Sytnikov</a>, <a href="https://publications.waset.org/abstracts/search?q=Mikhail%20Dubinin"> Mikhail Dubinin</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Filipeva"> Elena Filipeva</a>, <a href="https://publications.waset.org/abstracts/search?q=Dmitriy%20Sorokin"> Dmitriy Sorokin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Various variants of technical solutions aimed at improving the reliability of power supply to consumers of 110 kV substation are considered.

Weather phenomena, especially jet streams, are relatively permanent high winds blowing from west to east, located at average altitudes and latitudes in both hemispheres. To continuously extract energy from the jet-stream, the system is composed of a propelled plane and a wind turbine interconnected by a cable. This work presents the aerodynamic characteristics and the behavior of the cable that links the two subsystems and transmits energy from the turbine to the aircraft. Two ways of solving this problem are explored: numerically and analytically. After obtaining the optimal shape of the cross-section of the cable, its behavior is analyzed as a 2D problem solved numerically and analytically. Finally, a 3D extension could be considered by adding lateral forces.

The complexity of the whole network comprises numerous components that can fail and interrupt the power supply for the end user. Underground distribution systems are normally exposed to permanent faults, due to specific construction characteristics. In these systems, visual inspection cannot be performed. In order to enhance service restoration, accurate fault location techniques must be applied. This paper describes the different faults that affect the underground distribution system of SONELGAZ (National Society of Electricity and Gas of Algeria), and cable fault location procedure with impulse reflection method (TDR), based in the analyses of the cable response of the electromagnetic impulse, allows cable fault prelocation.

While this data serves the oil industry well, modern smart logging utilizes real-time downhole information, which automatically increases operational efficiency and optimizes intervention qualities. For example, downhole pressure, temperature, and depth measurement data can be transmitted through the electro-optical hybrid cable in the coiled tubing to surface operators on a real-time base. This paper mainly introduces the unique structural features and various applications of the electro-optical hybrid cables which were deployed into downhole with the help of coiled tubing technology. Fiber optic elements in the cable enable optical communications and distributed measurements, such as distributed temperature and acoustic sensing. The electrical elements provide continuous surface power for downhole tools, eliminating the limitations of traditional batteries, such as temperature, operating time, and safety concerns. The electrical elements also enable cable telemetry operation of cable tools. Both power supply and signal transmission were integrated into an electro-optical hybrid cable, and the downhole information can be captured by downhole electrical sensors and distributed optical sensing technologies, then travels up through an optical fiber to the surface, which greatly improves the accuracy of measurement data transmission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electro-optical%20hybrid%20cable" title="electro-optical hybrid cable">electro-optical hybrid cable</a>, <a href="https://publications.waset.org/abstracts/search?q=underground%20photoelectric%20composite%20cable" title=" underground photoelectric composite cable"> underground photoelectric composite cable</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20cable" title=" seismic cable"> seismic cable</a>, <a href="https://publications.waset.org/abstracts/search?q=coiled%20tubing" title=" coiled tubing"> coiled tubing</a>, <a href="https://publications.waset.org/abstracts/search?q=real-time%20monitoring" title=" real-time monitoring"> real-time monitoring</a> </p> <a href="https://publications.waset.org/abstracts/156152/application-of-electro-optical-hybrid-cables-in-horizontal-well-production-logging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156152.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">142</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">154</span> Experimental Investigation of Mechanical Friction Influence in Semi-Hydraulic Clutch Actuation System Over Mileage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Azarrudin%20M.%20A.">Abdul Azarrudin M.

The clutch pedal effort is one such customer touch feels in manual transmission vehicles, where the driver continuous to operate the clutch pedal in his entire the driving maneuvers. Hence optimum pedal efforts at green condition and over mileage to be ensured for fatigue free the driving. As friction is one the predominant factor and its tendency to challenge the technicality by causing the function degradation. One such semi-hydraulic systems shows load efficiency of about 70-75% over lifetime only due to the increase in friction which leads to the increase in pedal effort and cause fatigue to the vehicle driver. This work deals with the study of friction with different interfaces and its influence in the fulcrum points over mileage, with the objective of understanding the trend over mileage and determining the alternative ways of resolving it. In that one way of methodology is the reduction of friction by experimental investigation of various friction reduction interfaces like metal-to-metal interface and it has been tried out and is detailed further. Also, the specific attention has been put up considering the fulcrum load and its contact interfaces to move on with this study. The main results of the experimental data with the influence of three different contact interfaces are being presented with an ultimate intention of ending up into less fatigue with longer consistent pedal effort, thus smoothens the operation of the end user. The Experimental validation also has been done through rig-level test setup to depict the performance at static condition and in-parallel vehicle level test has also been performed to record the additional influences if any. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automobile" title="automobile">automobile</a>, <a href="https://publications.waset.org/abstracts/search?q=clutch" title=" clutch"> clutch</a>, <a href="https://publications.waset.org/abstracts/search?q=friction" title=" friction"> friction</a>, <a href="https://publications.waset.org/abstracts/search?q=fork" title=" fork"> fork</a> </p> <a href="https://publications.waset.org/abstracts/157212/experimental-investigation-of-mechanical-friction-influence-in-semi-hydraulic-clutch-actuation-system-over-mileage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157212.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">124</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">153</span> Effects of Aerodynamic on Suspended Cables Using Non-Linear Finite Element Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Justin%20Nwabanne">Justin Nwabanne</a>, <a href="https://publications.waset.org/abstracts/search?q=Sam%20Omenyi"> Sam Omenyi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeremiah%20Chukwuneke"> Jeremiah Chukwuneke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work presents structural nonlinear static analysis of a horizontal taut cable using Finite Element Analysis (FEA) method. The FEA was performed analytically to determine the tensions at each nodal point and subsequently, performed based on finite element displacement method computationally using the FEA software, ANSYS 14.0 to determine their behaviour under the influence of aerodynamic forces imposed on the cable. The convergence procedure is adapted into the method to prevent excessive displacements through the computations. The work compared the two FEA cases by examining the effectiveness of the analytical model in describing the response with few degrees of freedom and the ability of the nonlinear finite element procedure adopted to capture the complex features of cable dynamics with reference to the aerodynamic external influence. Results obtained from this work explain that the analytic FEM results without aerodynamic influence show a parabolic response with an optimum deflection at nodal points 12 and 13 with the cable weight at nodes 12 and 13 having the value -1.002936N while for the cable tension shows an optimum deflection value for nodes 12 and 13 at -189396.97kg/km. The maximum displacement for the cable system was obtained from ANSYS 14.0 as 4483.83 mm for X, Y and Z components of displacements at node number 2 while the maximum displacement obtained is 4218.75mm for all the directional components. The dynamic behaviour of a taut cable investigated has application in a typical power transmission line. Aerodynamic influences on the cables were considered using FEA approach by employing ANSYS 14.0 showed a complex modal behaviour as expected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamics" title="aerodynamics">aerodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=cable%20tension%20and%20weight" title=" cable tension and weight"> cable tension and weight</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=nodal" title=" nodal"> nodal</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20model" title=" non-linear model"> non-linear model</a>, <a href="https://publications.waset.org/abstracts/search?q=optimum%20deflection" title=" optimum deflection"> optimum deflection</a>, <a href="https://publications.waset.org/abstracts/search?q=suspended%20cable" title=" suspended cable"> suspended cable</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20line" title=" transmission line"> transmission line</a> </p> <a href="https://publications.waset.org/abstracts/55113/effects-of-aerodynamic-on-suspended-cables-using-non-linear-finite-element-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55113.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">278</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">152</span> Electromagnetic Simulation of Underground Cable Perforation by Nail </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Nour%20El%20Islam%20Ayad">Ahmed Nour El Islam Ayad</a>, <a href="https://publications.waset.org/abstracts/search?q=Tahar%20Rouibah"> Tahar Rouibah</a>, <a href="https://publications.waset.org/abstracts/search?q=Wafa%20Krika"> Wafa Krika</a>, <a href="https://publications.waset.org/abstracts/search?q=Houari%20Boudjella"> Houari Boudjella</a>, <a href="https://publications.waset.org/abstracts/search?q=Larab%20Moulay"> Larab Moulay</a>, <a href="https://publications.waset.org/abstracts/search?q=Farid%20Benhamida"> Farid Benhamida</a>, <a href="https://publications.waset.org/abstracts/search?q=Selma%20Benmoussa"> Selma Benmoussa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to evaluate the electromagnetic field of an underground cable of very high voltage perforated by nail.

The DCS is a seismic retrofit system composed of a high-strength steel cable and pressurized viscous dampers. The analysis model of the system is first derived using various link elements in SAP2000, and fragility curves of the structure retrofitted with the DCS and viscous dampers are obtained using incremental dynamic analyses. The analysis results show that the residual displacements of the structure equipped with the DCS are smaller than those of the structure with retrofitted with only conventional viscous dampers, due to the enhanced stiffness/strength and self-centering capability of the damped cable system. The fragility analysis shows that the structure retrofitted with the DCS has the least probability of reaching the specific limit states compared to the bare structure and the structure with viscous damper. It is also observed that the initial cost of the DCS method required for the seismic retrofit is smaller than that of the structure with viscous dampers and that the LCC of the structure equipped with the DCS is smaller than that of the structure with viscous dampers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damped%20cable%20system" title="damped cable system">damped cable system</a>, <a href="https://publications.waset.org/abstracts/search?q=fragility%20curve" title=" fragility curve"> fragility curve</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20cost" title=" life cycle cost"> life cycle cost</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20retrofit" title=" seismic retrofit"> seismic retrofit</a>, <a href="https://publications.waset.org/abstracts/search?q=self-centering" title=" self-centering"> self-centering</a> </p> <a href="https://publications.waset.org/abstracts/77662/life-cycle-cost-evaluation-of-structures-retrofitted-with-damped-cable-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77662.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">550</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">150</span> Numerical Simulation and Experimental Study on Cable Damage Detection Using an MFL Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jooyoung%20Park">Jooyoung Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Junkyeong%20Kim"> Junkyeong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Aoqi%20Zhang"> Aoqi Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Seunghee%20Park"> Seunghee Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Non-destructive testing on cable is in great demand due to safety accidents at sites where many equipments using cables are installed. In this paper, the quantitative change of the obtained signal was analyzed using a magnetic flux leakage (MFL) method. A two-dimensional simulation was conducted with a FEM model replicating real elevator cables. The simulation data were compared for three parameters (depth of defect, width of defect and inspection velocity). Then, an experiment on same conditions was carried out to verify the results of the simulation. Signals obtained from both the simulation and the experiment were transformed to characterize the properties of the damage. Throughout the results, a cable damage detection based on an MFL method was confirmed to be feasible. In further study, it is expected that the MFL signals of an entire specimen will be gained and visualized as well. <p class="card-text"><strong>Keywords:</strong> <a
