Study on the simulation of thermal-structure coupling on retarding disk and analysis of brake component model

Luo Wenhua, Jiang Shuying


Brake system is an important part of automobile safety performance; brake is its core element, directly affecting the safety of driver. Based on the principle of disc brake friction, the characteristic of thermal-structure coupling has a great influence on such parameters as the thermal fatigue life and resonance of shouting. This paper suggest a proper simplification of the car’s front disc brake. The thermal-structural coupling of the brake disc on the emergency braking condition has been simulated by means of finite element software. The thermal fatigue life is predicted, and the modal analysis of brake is finally carried out.
