Design and Thermostructural Analysis of Automotive Disc Brake

A brake is a device to stop the motion of a machine, by means of which artificial frictional resistance is applied to moving machine member. In the process of performing this operate; the brakes draw either kinetic energy of the moving member or the potential energy ceased by objects being brought down by hoists, elevators, etc. The energy sucked by the brakes is dissipated in the form of heat energy. Disc brake is a familiar automotive application where they are applied extensively for car and motorcycle wheels. In the past, surface roughness and wear at the pad interface have rarely been counted in studies of thermal analysis of a disc brake assembly using finite element method. The main purpose of this project is to Optimization of Automotive Brake Disc and analysis the thermal and structural conduct of the dry contact between the brake disc and pads during the braking phase. The thermal-structural analysis to determine the thermal flux and the Von Misses stresses built in the disc. The objective of the project is the design, analysis and optimization of solid and ventilated disc brake using Ansys. The ventilated brake disc assembly is built by a 3D model in Catia and imported to Ansys to evaluate the stress fields and thermal flux's which are established in the disc with the pressure on the pads and in the conditions of tightening of the disc.
