Thermal Fatigue FE Analysis of Brake Disc under Different Parameters

Abstract

A brake is the most important part of a vehicle necessary for good control of vehicle to avoid accidents. Brakes are required to stop the vehicle within minimum possible distance and it is done by converting kinetic energy of the vehicle into heat energy by friction which is dissipated into atmosphere. Most important requirement of brakes is that they should have good anti fade, anti-wear properties & ability to withstand large temperature generated during braking. Due to generation of heat by rise in temperature during braking, thermal fatigue failure of brake can occur which hampers normal braking of vehicle. So it is necessary to analyze thermal behavior of disk under elevated temperature to get optimum design of disc. Objective of this paper is to Compare thermal behavior of solid disk i.e. disk without hole and then disk with hole using FEA approach which can assist in disc rotor design and analysis to avoid thermal damage of disk brake.
