The investigation was based on a simple experimental formulation, consisting of seven friction materials with different proportions of abrasives (ZrSiO4 and Fe2O3) and friction modifiers (cashew dust). The friction materials were evaluated using a Chase friction tester. The tribological properties, such as the wear resistance and friction stability, depending on the test temperature and the number of braking were obtained related to the friction material ingredient proportions. The results showed that the tribological properties of the brake pad were greatly affected by the abrasive and then cashew dust proportion. <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=friction" title=" friction"> friction</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a>, <a href="https://publications.waset.org/abstracts/search?q=abrasives" title=" abrasives"> abrasives</a> </p> <a href="https://publications.waset.org/abstracts/12601/effects-of-ingredients-proportions-on-the-friction-performance-of-a-brake-pad-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12601.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">440</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">746</span> Effect of Rotation Speed on Microstructure and Microhardness of AA7039 Rods Joined by Friction Welding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Karakoc">H.

Friction welding joints were carried out using a rotational friction welding machine. Friction welds were obtained under different rotational speeds between (2700 and 2900 rpm). The friction pressure of 10 MPa and friction time of 30 s was kept constant. The cross sections of joints were observed by optical microscopy. The microstructures were analyzed using scanning electron microscope/energy dispersive X-ray spectroscopy. The Vickers micro hardness measurement of the interface was evaluated using a micro hardness testing machine.

The estimator only needs a few, usually known, steering system parameters. Friction occurs on almost every mechanical system and has a negative influence on high-precision position control. This is demonstrated on a steering angle controller for highly automated driving. In this steering system the friction induces limit cycles which cause oscillating vehicle movement when the vehicle follows a given reference trajectory. When compensating the friction with the introduced estimator, limit cycles can be suppressed. This is demonstrated by measurements in a series vehicle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction%20estimation" title="friction estimation">friction estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20compensation" title=" friction compensation"> friction compensation</a>, <a href="https://publications.waset.org/abstracts/search?q=steering%20system" title=" steering system"> steering system</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20vehicle%20guidance" title=" lateral vehicle guidance"> lateral vehicle guidance</a> </p> <a href="https://publications.waset.org/abstracts/27641/friction-estimation-and-compensation-for-steering-angle-control-for-highly-automated-driving" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27641.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">515</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">744</span> Friction Calculation and Simulation of Column Electric Power Steering System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Hamid%20Mirmohammad%20Sadeghi">Seyed Hamid Mirmohammad Sadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Raffaella%20Sesana"> Raffaella Sesana</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Maffiodo"> Daniela Maffiodo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents a procedure for friction calculation of column electric power steering (C-EPS) system which affects handling and comfort in driving. The friction losses estimation is obtained from experimental tests and mathematical calculation. Parts in C-EPS mainly involved in friction losses are bearings and worm gear. In the theoretical approach, the gear geometry and Hertz law were employed to measure the normal load and the sliding velocity and contact areas from the worm gears driving conditions. The viscous friction generated in the worm gear was obtained with a theoretical approach and the result was applied to model the friction in the steering system. Finally, by viscous friction coefficient and Coulomb friction coefficient, values of friction in worm gear were calculated. According to the Bearing Company and the characteristics of each bearing, the friction torques due to load and due to speed were calculated. A MATLAB Simulink model for calculating the friction in bearings and worm gear in C-EPS were done and the total friction value was estimated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction" title="friction">friction</a>, <a href="https://publications.waset.org/abstracts/search?q=worm%20gear" title=" worm gear"> worm gear</a>, <a href="https://publications.waset.org/abstracts/search?q=column%20electric%20power%20steering%20system" title=" column electric power steering system"> column electric power steering system</a>, <a href="https://publications.waset.org/abstracts/search?q=simulink" title=" simulink"> simulink</a>, <a href="https://publications.waset.org/abstracts/search?q=bearing" title=" bearing"> bearing</a>, <a href="https://publications.waset.org/abstracts/search?q=EPS" title=" EPS"> EPS</a> </p> <a href="https://publications.waset.org/abstracts/58098/friction-calculation-and-simulation-of-column-electric-power-steering-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58098.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">358</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">743</span> Identification of Dynamic Friction Model for High-Precision Motion Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martin%20Goubej">Martin Goubej</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomas%20Popule"> Tomas Popule</a>, <a href="https://publications.waset.org/abstracts/search?q=Alois%20Krejci"> Alois Krejci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with experimental identification of mechanical systems with nonlinear friction characteristics.

Some important factors that effected directly by friction are: stress, strain, required load, wear of surfaces and then geometrical parameters. In order to control friction effects permanent lubrication is necessary. In this article, the friction coefficient is elicited by the most effective method, ring compression tests.

The coefficient of friction in Stribeck curve depends on sliding velocity and contact pressure. The springback behavior of mild steel and aluminum alloy 6022-T4 sheets was studied experimentally and using numerical simulations with ABAQUS software with two types of friction model: Coulomb friction and Stribeck friction. The influence of forming speed on springback behavior was studied experimentally and numerically. The results showed that Stribeck-type friction model has better results in predicting springback in sheet metal forming. The FE prediction error for mild steel and 6022-T4 AA is 23.8%, 25.5% respectively, using Coulomb friction model and 11%, 13% respectively, using Stribeck friction model. These results show that Stribeck model is suitable for simulation of sheet metal forming especially at higher forming speed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction" title="friction">friction</a>, <a href="https://publications.waset.org/abstracts/search?q=L-bending" title=" L-bending"> L-bending</a>, <a href="https://publications.waset.org/abstracts/search?q=springback" title=" springback"> springback</a>, <a href="https://publications.waset.org/abstracts/search?q=Stribeck%20curves" title=" Stribeck curves"> Stribeck curves</a> </p> <a href="https://publications.waset.org/abstracts/7441/simulation-of-kinetic-friction-in-l-bending-of-sheet-metals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7441.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">491</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">738</span> Friction Stir Welding Process as a Solid State Joining -A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Anees%20Siddiqui">Mohd Anees Siddiqui</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20A.%20H.%20Jafri"> S.

Friction stir welding is used for joining of two plates which are applied compressive force by using fixtures over the work table. This is a non consumable type welding technique in which a rotating tool of cylindrical shape is used. Process parameters such as tool geometry, joint design and process speed are discussed in the paper.

The dependence of the dynamic coefficient of friction on the main influencing factors (vertical load, temperature, and sliding distance) was investigated by evaluating their mutual interaction. Multiple regression analysis showed a high polynomial dependence (adjusted R2 > 0.98). The resistance of the composite to thermo-mechanical effects determines how temperature and force factors affect the magnitude of the coefficient of friction. WPC-B composite has the lowest friction and highest resistance compared to WPC-A, while composite and cemented carbide materials wear the least. Energy dispersive spectroscopy (EDS), based on elemental composition, provided important insights into the friction process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction" title="friction">friction</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=carbide" title=" carbide"> carbide</a>, <a href="https://publications.waset.org/abstracts/search?q=factors" title=" factors"> factors</a> </p> <a href="https://publications.waset.org/abstracts/170669/friction-behavior-of-wood-plastic-composites-against-uncoated-cemented-carbide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170669.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">83</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">736</span> Tribological Investigation of Piston Ring Liner Assembly</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bharatkumar%20Sutaria">Bharatkumar Sutaria</a>, <a href="https://publications.waset.org/abstracts/search?q=Tejaskumar%20Chaudhari"> Tejaskumar Chaudhari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An engine performance can be increased by minimizing losses.

Accurate modelling of manipulation requires identification of forces and mechanical knowledge in the Nanoscale which are different from macro world. Due to the importance of the adhesion forces and the interaction of surfaces at the nanoscale several friction models were presented. In this research, friction and normal forces that are applied on the AFM by using of the dynamic bending-torsion model of AFM are obtained based on Hurtado-Kim friction model (HK), Johnson-Kendall-Robert contact model (JKR) and Greenwood-Williamson roughness model (GW). Finally, the effect of standard deviation of asperities height on the normal load, friction force and friction coefficient are studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atomic%20force%20microscopy" title="atomic force microscopy">atomic force microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=contact%20model" title=" contact model"> contact model</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20coefficient" title=" friction coefficient"> friction coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=Greenwood-Williamson%20model" title=" Greenwood-Williamson model"> Greenwood-Williamson model</a> </p> <a href="https://publications.waset.org/abstracts/85332/modelling-of-atomic-force-microscopic-nano-robots-friction-force-on-rough-surfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85332.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">199</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">733</span> Friction Stir Welding of Aluminum Alloys: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20K.%20Tiwari">S.

High strength aluminum alloys are widely used in aircraft and marine industries. Generally, the mechanical properties of fusion-welded aluminum joints are poor. As friction stir welding occurs in the solid state, no solidification structures are created thereby eliminating the brittle and eutectic phases common in fusion welding of high strength aluminum alloys.

In recent years, some joining techniques have been developed to achieve a good bonding between these materials such as brazing, diffusion bonding, ultrasonic joining and friction welding. In this work, AA1100 aluminum alloy rods were welded with Alumina 99.9 wt% ceramic rods, by friction welding. The effect of friction pressure on mechanical and structural properties of welded joints was studied. The welding was performed by direct friction welding machine. The welding samples were rotated at a constant rotational speed of 900 rpm, friction time of 4 sec, forging strength of 18 MPa, and forging time of 3 sec. Three different friction pressures were applied to 20, 34 and 45 MPa. The three-point bending test and Vickers microhardness measurements were used to evaluate the strength of the joints and investigate the mechanical properties of the welding area. The microstructure of joints was examined by optical microscopy (OM), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The results show that bending strength increased, and then decreased after reaching a maximum value, with increasing friction pressure. The SEM observation shows that the increase in friction pressure led to the appearance of cracks in the microstructure of the interface area, which is decreasing the bending strength of joints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=welding%20of%20ceramic%20to%20aluminum" title="welding of ceramic to aluminum">welding of ceramic to aluminum</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20welding" title=" friction welding"> friction welding</a>, <a href="https://publications.waset.org/abstracts/search?q=alumina" title=" alumina"> alumina</a>, <a href="https://publications.waset.org/abstracts/search?q=AA1100%20aluminum%20alloy" title=" AA1100 aluminum alloy"> AA1100 aluminum alloy</a> </p> <a href="https://publications.waset.org/abstracts/88398/effect-of-friction-pressure-on-the-properties-of-friction-welded-aluminum-ceramic-dissimilar-joints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88398.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">129</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">731</span> Friction and Wear, Including Mechanisms, Modeling,Characterization, Measurement and Testing (Bangladesh Case)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gor%20Muradyan">Gor Muradyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper is about friction and wear, including mechanisms, modeling, characterization, measurement and testing case in Bangladesh. Bangladesh is a country under development, A lot of people live here, approximately 145 million. The territory of this country is very small. Therefore buildings are very close to each other. As the pipe lines are very old, and people get almost dirty water, there are a lot of ongoing projects under ADB. In those projects the contractors using HDD machines (Horizontal Directional Drilling ) and grundoburst. These machines are working underground. As ground in Bangladesh is very sludge, machine can't work relevant because of big friction in the soil. When drilling works are finished machine is pulling the pipe underground. Very often the pulling of the pipes becomes very complicated because of the friction. Therefore long section of the pipe laying can’t be done because of a big friction. In that case, additional problems rise, as well as additional work must be done. As we mentioned above it is not possible to do big section of the pipe laying because of big friction in the soil, Because of this it is coming out that contractors must do more joints, more pressure test. It is always connected with additional expenditure and losing time. This machine can pull in 75 mm to 500 mm pipes connected with the soil condition. Length is possible till 500m related how much friction it will had on the puller. As less as much it can pull. Another machine grundoburst is not working at this soil condition at all. The machine is working with air compressor. This machine are using for the smaller diameter pipes, 20 mm to 63 mm. Most of the cases these machines are being used for the installing of the house connection pipes, for making service connection. To make a friction less contractors using bigger pulling had then the pipe. It is taking down the friction, But the problem of this machine is that it can't work at sludge. Because of mentioned reasons the friction has a big mining during this kind of works. There are a lot of ways to reduce the friction. In this paper we'll introduce the ways that we have researched during our practice in Bangladesh. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bangladesh" title="Bangladesh">Bangladesh</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20and%20wear" title=" friction and wear"> friction and wear</a>, <a href="https://publications.waset.org/abstracts/search?q=HDD%20machines" title=" HDD machines"> HDD machines</a>, <a href="https://publications.waset.org/abstracts/search?q=reducing%20friction" title=" reducing friction"> reducing friction</a> </p> <a href="https://publications.waset.org/abstracts/33722/friction-and-wear-including-mechanisms-modelingcharacterization-measurement-and-testing-bangladesh-case" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33722.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">317</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">730</span> Modeling of the Friction Behavior of Carbon/Epoxy Prepreg Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Aveiga">David Aveiga</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Gonzalez"> Carlos Gonzalez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thermoforming of pre-impregnated composites (prepreg) is the most employed process to build high-performance composite structures due to their visible advantage over alternative manufacturing techniques.

Two rough surfaces, when pressed against each other, can get into a formation where the summits of asperities of one surface lock into the valleys of the other surface. The amount of interlock depends on the geometry of the two surfaces. We suggest the friction force may then be proportional to the amount of interlock; this explains Superlubricity as the situation where there is little interlock. Then the friction force will be directly proportional to the normal force as it is related to the work necessary to lift the upper surface in order to clear the interlock. To investigate this model, we simulate the contact of two surfaces. In order to validate our model, we first investigate Amontons‘ law. Assuming that asperities retain deformations in the time scale while the top asperity moves across the lattice spacing Amonton’s law is observed. Structural superlubricity is examined by the hypothesis that surfaces are very rigid and there is no deformation in asperities. This may happen at small normal forces. When two identical surfaces come into contact, rotating the top surface we observe a peak in friction force near the angle of orientation where the two surfaces can interlock. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction" title="friction">friction</a>, <a href="https://publications.waset.org/abstracts/search?q=amonton%60s%20law" title=" amonton`s law"> amonton`s law</a>, <a href="https://publications.waset.org/abstracts/search?q=superlubricity" title=" superlubricity"> superlubricity</a>, <a href="https://publications.waset.org/abstracts/search?q=contact%20model" title=" contact model"> contact model</a> </p> <a href="https://publications.waset.org/abstracts/128468/an-interlock-model-of-friction-and-superlubricity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128468.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">147</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">727</span> Dry Friction Occurring in the Suspensions for Passive and Switchable Damper Systems and Its Effect on Ride Comfort</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aref%20M.%20A.%20Soliman">Aref M.

One of the various active suspensions, which have been shown to have considerable practical potential, is a switchable damper suspension system. In this paper, vehicle ride comfort for the passive and switchable damper suspension systems as affected by the value of frictional force generated in springs is discussed. A mathematical model of a quarter vehicle model for two setting switchable damper suspension system with dry friction force is developed to evaluate vehicle ride comfort in terms of suspension performance criteria. The vehicle itself is treated as a rigid body undergoing vertical motions. Comparisons between passive and switchable damper suspensions systems with dry friction force in terms of ride performance are also discussed. The results showed that the ride comfort for the passive and switchable damper suspension systems was deteriorated due to dry friction occurring in the suspensions. The two setting switchable damper with and without dry friction force gives better ride improvements compared with the passive suspension system. Also, the obtained results show an optimum value of damping ratio of the passive suspension system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ride%20comfort" title="ride comfort">ride comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=dry%20friction" title=" dry friction"> dry friction</a>, <a href="https://publications.waset.org/abstracts/search?q=switchable%20damper" title=" switchable damper"> switchable damper</a>, <a href="https://publications.waset.org/abstracts/search?q=passive%20suspension" title=" passive suspension"> passive suspension</a> </p> <a href="https://publications.waset.org/abstracts/82923/dry-friction-occurring-in-the-suspensions-for-passive-and-switchable-damper-systems-and-its-effect-on-ride-comfort" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82923.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">372</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">726</span> Assessment of the High-Speed Ice Friction of Bob Skeleton Runners</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agata%20Tomaszewska">Agata Tomaszewska</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Kamps"> Timothy Kamps</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20R.%20Turnock"> Stephan R.

It is believed that the friction between the runners and ice significantly contributes to the amount of the total energy loss during a bob skeleton descent. There is only limited available experimental data regarding the friction of bob skeleton runners or indeed steel on the ice at high sliding speeds ( > 20 m/s). Testing methods used to investigate the friction of steel on ice in winter sports have been outlined, and their accuracy and repeatability discussed. A system thinking approach was used to investigate the runner-ice interaction during sliding and create concept designs of three ice tribometers. The operational envelope of the bob skeleton system has been defined through mathematical modelling. Designs of a drum, linear and inertia pin-on-disk tribometers were developed specifically for bob skeleton runner testing with the requirement of reaching up to 40 m/s speed and facilitate fresh ice sliding. The design constraints have been outline and the proposed solutions compared based on the ease of operation, accuracy and the development cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bob%20skeleton" title="bob skeleton">bob skeleton</a>, <a href="https://publications.waset.org/abstracts/search?q=ice%20friction" title=" ice friction"> ice friction</a>, <a href="https://publications.waset.org/abstracts/search?q=high-speed%20tribometers" title=" high-speed tribometers"> high-speed tribometers</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20friction" title=" sliding friction"> sliding friction</a> </p> <a href="https://publications.waset.org/abstracts/72268/assessment-of-the-high-speed-ice-friction-of-bob-skeleton-runners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72268.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">261</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">725</span> Study of Mechanical Properties of Aluminium Alloys on Normal Friction Stir Welding and Underwater Friction Stir Welding for Structural Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lingaraju%20Dumpala">Lingaraju Dumpala</a>, <a href="https://publications.waset.org/abstracts/search?q=Laxmi%20Mohan%20Kumar%20Chintada"> Laxmi Mohan Kumar Chintada</a>, <a href="https://publications.waset.org/abstracts/search?q=Devadas%20Deepu"> Devadas Deepu</a>, <a href="https://publications.waset.org/abstracts/search?q=Pravin%20Kumar%20Yadav"> Pravin Kumar Yadav</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Friction stir welding is the new-fangled and cutting-edge technique in welding applications; it is widely used in the fields of transportation, aerospace, defense, etc. For thriving significant welding joints and properties of friction stir welded components, it is essential to carry out this advanced process in a prescribed systematic procedure. At this moment, Underwater Friction Stir Welding (UFSW) Process is the field of interest to do research work. In the continuous assessment, the study of UFSW process is to comprehend problems occurred in the past and the structure through which the mechanical properties of the welded joints can be value-added and contributes to conclude results an acceptable and resourceful joint.

Several types of lubricants are available. Their effectiveness had been tested mostly through direct shear tests. These testing conditions are quite different than those when the tested soil is placed in the container. Thus, the shear strengths measured from direct shear tests may not be totally representative of those of interfaces between the tested soil and the sidewalls of container. In this paper, the effectiveness of different lubricants used to reduce the friction (shear strength) of soil-structure interfaces has been studied. Results show that the selected lubricants do not significantly reduce the sidewall friction (shear strength). Rather, the application of wax, graphite, grease or lubricant oil has effect to increase the sidewall shear strength due probably to the high viscosity of such materials. Subsequently, the application of lubricants between tested soil and sidewall and neglecting the friction (shear strength) along the sidewalls may lead to inaccurate test results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arching" title="arching">arching</a>, <a href="https://publications.waset.org/abstracts/search?q=friction" title=" friction"> friction</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20tests" title=" laboratory tests"> laboratory tests</a>, <a href="https://publications.waset.org/abstracts/search?q=lubricants" title=" lubricants"> lubricants</a> </p> <a href="https://publications.waset.org/abstracts/81128/an-experimental-study-of-the-effectiveness-of-lubricants-in-reducing-the-sidewall-friction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81128.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">281</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">723</span> Comparing Friction Force Between Track and Spline Using graphite, Mos2, PTFE, and Silicon Dry Lubricant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20De%20Maaijer">M.

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">719</span> Optimal Design of Friction Dampers for Seismic Retrofit of a Moment Frame</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyungoo%20Kang">Hyungoo Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinkoo%20Kim"> Jinkoo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigated the determination of the optimal location and friction force of friction dampers to effectively reduce the seismic response of a reinforced concrete structure designed without considering seismic load. To this end, the genetic algorithm process was applied and the results were compared with those obtained by simplified methods such as distribution of dampers based on the story shear or the inter-story drift ratio. The seismic performance of the model structure with optimally positioned friction dampers was evaluated by nonlinear static and dynamic analyses. The analysis results showed that compared with the system without friction dampers, the maximum roof displacement and the inter-story drift ratio were reduced by about 30% and 40%, respectively. After installation of the dampers about 70% of the earthquake input energy was dissipated by the dampers and the energy dissipated in the structural elements was reduced by about 50%. In comparison with the simplified methods of installation, the genetic algorithm provided more efficient solutions for seismic retrofit of the model structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction%20dampers" title="friction dampers">friction dampers</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20design" title=" optimal design"> optimal design</a>, <a href="https://publications.waset.org/abstracts/search?q=RC%20buildings" title=" RC buildings"> RC buildings</a> </p> <a href="https://publications.waset.org/abstracts/43940/optimal-design-of-friction-dampers-for-seismic-retrofit-of-a-moment-frame" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43940.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">244</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">718</span> Elaboration and Investigation of the New Ecologically Clean Friction Composite Materials on the Basis of Nanoporous Raw Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lia%20Gventsadze">Lia Gventsadze</a>, <a href="https://publications.waset.org/abstracts/search?q=Elguja%20Kutelia"> Elguja Kutelia</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Gventsadze"> David Gventsadze</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of the article is to show the possibility for the development of a new generation, eco-friendly (asbestos free) nano-porous friction materials on the basis of Georgian raw materials, along with the determination of technological parameters for their production, as well as the optimization of tribological properties and the investigation of structural aspects of wear peculiarities of elaborated materials using the scanning electron microscopy (SEM) and Auger electron spectroscopy (AES) methods. The study investigated the tribological properties of the polymer friction materials on the basis of the phenol-formaldehyde resin using the porous diatomite filler modified by silane with the aim to improve the thermal stability, while the composition was modified by iron phosphate, technical carbon and basalt fibre. As a result of testing the stable values of friction factor (0.3-0,45) were reached, both in dry and wet friction conditions, the friction working parameters (friction factor and wear stability) remained stable up to 500 OC temperatures, the wear stability of gray cast-iron disk increased 3-4 times, the soundless operation of materials without squeaking were achieved.
