Content
During braking, the kinetic energy and potential energies of a moving vehicle are converted into the thermal energy through frictional heat between the brake disc and the pads. Most of thermal energy dissipated through the brake disc. The object of the present study is simulation of heating and cooling processes of brake disc to investigate temperature field and temperature variation during driving along a downhill road. The velocity of automobile is limited by repeated brake when the speed exceeds to the maximum limited. The pad-disc brake assembly is built by 3D model and applied appropriate boundary condition. In the simulation process, the mechanical loads are applied to the thermo-mechanical coupling model in order to simulate the process of heat produced by friction. The Analysis results are compared to the measured data obtained from the downhill road brake experiment. The temperature field distribution in the disc under repeated braking presents a non-uniformity characteristic.
