The motor controller of the integrated drive system for electric vehicles has the risk of sweep frequency vibration fatigue (SFVF) failure in the frequency range of 100 ∼ 440 Hz. In this paper, a finite element simulation method of SFVF for an integrated motor controller is introduced. The failure position of the motor controller component is predicted using this simulation method, which is consistent with the fracture position of the sweep frequency vibration fatigue test (SFVFT). This indicates that the simulation method is accurate. And the structural optimization suggestions are also put forward using this method. The optimized motor controller meets the requirements of SFVFT. This indicates that it is feasible to use this method during the design process of the motor controller for integrated drive system.
