Temperature Field and Thermal Stress Simulation of Solid Brake Disc using Non-axisymmetric Model

The brake system is an important part of automobile safety system. The disc brake system is divided into two parts: a rotating axisymmetrical disc, and the stationary pads. The frictional heat, which is generated on the interface of the disc and pads, can cause high temperature during the braking process. The frictional heat source (the pads) is moving on the disc and the location is depended on time. In our study, we apply a moving heat souse which is defined by time and space variable on the frictional surface, in order to simulate the friction heat behavior accurately during the braking. The object of present work is determination of temperature distribution, and thermal stress in the solid disc by non-axisymmetric 3D modeling for the repeated brake.
