Self-Excited Torsional Vibrations of Drive System of Locomotive under Slippage

  • A simplified model for torsional vibrations of a single wheel-set drive system was used to study torsional vibrations of a locomotive under slippage.In the model,torsional stiffness of the shaft of a wheel set and that between the traction motor and the wheel-set were taken into account.The phase trajectories of the torsional vibrations are a set of stable limit cycles,signifying self-excited vibrations when the average wheel-rail creepage is over the critical value.Frequencies of torsional vibrations with different operating modes were calculated.The results show that the vibration frequency is in accordance with the natural frequency of the drive system when self-excited vibrations happen.Therefore,analyzing the vibration frequency of wheel-sets is a measure to identify wheel-rail slippage.
