Abstract

Based on the tensile and compression experiments of the materials of brake disk and friction plate of disk brake, the elastic modulus and Poisson's ratio of brake disk and friction plate were measured respectively. In order to analyze the temperature and stress fields of brake disk and friction plate, the 3D model of brake disc and friction plate were established, then using Ansa for mesh division and utilizing the finite element method about the function of thermal-mechanical coupling simulation to finish that. What's more, combined with the simulation of temperature and stress fields, experiment of the temperature field about brake disc was conducted to explore the reasons for the formation of thermal fatigue. The result shows that the generation of thermal fatigue of brake disk is affected by the surface temperature gradient and the temperature's changing frequency, and the cracks were mainly concentrated in the annular and high temperature areas.
