    Abstract
  • In order to improve the riding comfort of vehicle, the vibrant response characteristic of vehicle was studied, a dynamics model of vehicle system was set up, frequency-domain mode parameters on the hunting mode of bogie and the natural mode of car body were calculated, and stationarity indices of vehicle at the different speeds were computed in time-domain.Computation result shows that the hunting frequency of bogie and the primary frequency of track irregularities increase with the increase of running velocity, but the natural frequency of car body has no change; they must approach the natural frequency of car body and take place resonance at certain speed, and the resonance will badly worsen the riding comfort of vehicle.So in order to improve the comfort, some proper measures should be taken to keep the resonance speed away from the common running speed of vehicle.
