Braking system represents one of the most fundamental safety critical components in modern vehicles. Brake absorbs kinetic energy of the rotating parts (Wheels) and the energy is dissipated in the form of heat energy to the surrounding atmosphere. It decelerates or stops the vehicle. When brake is applied to the disc brake it is subjected to high stress, thus it may suffer structural and wear issues. Hence for the better performance, structural, stress and the thermal analysis is preferred to choose low stress material. The objective of this paper is to model and analyse stress concentration, structural deformation and thermal gradient of disc brake. Here the disc brake is designed by using Solidworks and analysis is done by ANSYS workbench R 14.5.
