Abstract

In high-speed train, since parts of driving medium are not fully rigid, it is common to have fluctuation of rotating speed in different sizes and phase leading to shaft torsional vibration in driving devices for kinds of reasons. Slight vibration can change the torsional stress on axis, which aggravate axial fatigue damage and decrease the service life, severe vibration may result in shaft damage, which have effect on operation security of the train. This paper firstly established two-mass model of drive system and got the transfer function, introduced the mechanism of torsional vibration through theoretical analysis, which proved that torsional vibration is a system stability problem. Then the author established the Simulink model of traction drive system, which proved unstable factor like speed step and load disturbance can result in shaft torsional vibration phenomenon. Finally analyzes influence parameters of vibration frequency and amplitude by simulation.
