Thermal Stress Analysis of Heavy Truck Brake Disc Rotor

While braking, most of the kinetic energy are converted into thermal energy and increase the disc temperature. This project consists of thermal stress analysis on heavy truck brake disc rotor for steady state and transient condition. The heat dissipated along the brake disc surface during the periodic brakingvia conduction, convection and radiation. In order to get the stable and accurate result of element size, time step selection is very important and all of these aspects are discussed in this paper. The findings of this research provide a useful design tool to improve the brake performance of disc brake system
