Abstract High-speed train’s traction drive system is a typical electromechanical coupling system, and the motor torque contains ripples of different frequencies and amplitudes. Frequency of motor stator changes with velocity, so the frequency of torque pulsation varies a lot. The driving system has resonance frequency, and the devices would be vibrated when frequency of torque ripple is close to the resonance frequency. First, this paper analyses the torque ripple caused by inverter’s nonlinear factors. Then, the paper establishes the model of shifts to research the vibration frequency. Finally, the author analyses the forced vibration of the mechanical structure excited by torque ripple, and the simulation result shows that the vibration would be aggravated when the frequency of the torque ripple is in accord with the resonance frequency.
