Abstract
This paper presents an analysis method to estimate the thermal performance of a disc in a vehicle considering braking conditions and the characteristics of hydraulic devices such as the booster, master cylinder and proportional valve. The whole braking pressure transfer process in the hydraulic brake system from its generating by the pedal to action on the pad is analytically determined. The heat flux generated in the disc brake module is calculated by assuming that the braking energy changes into thermal energy. Heat flux is applied to the finite element disc model, and the temperature rise and deformation of a disc are estimated by performing the thermo-mechanical analysis. The analysis results are discussed and the analytical process and simulation model are verified.
