| Abstract: | With a front disk brake of an electric vehicle as the research object, by using the nonlinear multiphysics field of the ABAQUS software, the finite element model of the disc brake was established. Then the thermal-structure coupling field was analyzed using simulation based on the steps, loads and boundary conditions which were ascertained. Through the simulation analysis about transient stress field and temperature field of the thermal-structure coupling field of the electric vehicle under the circumstance of emergency braking condition, the disk＇s distribution map of temperature field and stress field could be obtained, and it was concluded that the disk of the electric vehicle met the requirements of intensity. |
