摘要
利用简化的轮对振动模型进行了轮对在周期性轨缝冲击作用下的响应计算，由计算结果可以看出，轮轨冲击力随着车辆运行速度的提高在迅速增长，但是阻尼对冲击力能起到有效的抑制作用．对于速度达到１４０～１６０ｋｍ／ｈ的提速列车，甚至达到２００ｋｍ／ｈ的高速列车，当选取相对阻尼系数ξ＝０．
On the basis of vibration model we calculated response of wheel in the period of impulses. According to the results we know the more the speed of vehicle is the more the track impulsive force is however impulsive force can be effectively controlled by damping. When the speed of vehicle goes beyond 140 km/h, if the damping coefficient is selected ξ = 0.07 , the good function of dynamics will be gotten.
