Abstract: A clutch is a critical component of a vehicle to transfer torque and speed from a driving shaft to a driven shaft with the use of friction. The efficiency of the clutch depends enormously on friction that result in heat generation during engagement and disengagement. Rapid heat dissipation is primordial to prevent the friction plate from reaching the fade temperature where friction coefficient decreases. The present study is an attempt to model and analyze structural deformation, stress concentration, elastic strain, thermal gradient and heat flux distribution of a copper alloy friction lining and structural steel friction lining of a clutch plate with the help of finite elements methods software. It is observed that copper alloy frictional lining of clutch plate dissipates frictional heat at a faster rate than structural steel frictional lining of clutch plate. The design is done in Solidworks 2016 and the FEM analysis is carried out using ANSYS 16.0 Transient Structural and Steady State Thermal workbench.

1. Introduction: A clutch is a mechanism that allows transmission of power from a motor to other driven components by engagement and disengagement of the friction plate from the flywheel.[1] It is an indispensable part in vehicle application located between the motor and transmission of automobile.[2-3] The main components of a friction clutch are flywheel, friction plate, diaphragm ring and pressure plate. The friction plate is sandwiched between the flywheel and pressure plate during engagement and released from flywheel during disengagement.[4] The operation of the single plate clutch is as follows: The friction plate is mounted on a hub that can moves freely and axially along a spline onto the driven shaft. During engagement, the pressure plate pushes the friction plate using diaphragm spring onto the flywheel which is mounted on the driving shaft. Hence providing torque and speed transmission. During disengagement pressure releases friction plate from flywheel thus disrupting flow of power.[5] Common friction material are classified as semi-metallic, ceramic and organic. The main purpose of friction materials is to 1|P a g e
