Sequentially Coupled Thermal-Mechanical Analysis of the Brake Disc Used in Air Disc Brake

Abstract:

The basic theory involved in the coupled thermal mechanical analysis is presented briefly. Base on the contact theory, friction heat generation theory and heat transfer theory, the heat distribution ratio between the disc and brake pad is determined, a 3D transient heat conduction differential equation and corresponding boundary conditions are established. Finally, according to the analysis requirement, the business analysis software ABAQUS is chosen as sequentially coupled thermal mechanical analysis solver. In order to know the temperature of discs friction surface during the cycle braking and continuous braking processes, a sequentially coupled thermal mechanical analysis model of the disc is established according to the energy dissipation theory. The temperature field and stress field of the disc during emergency braking, repeat braking and continuous braking processes are carried out based on this model.
