摘　　要：基于力学原理研究车辆在桥面斜坡空档滑行的问题。首先分析车辆空档滑行时的受力情况,建立动力学模型。然后针对空挡滑行刹车所引起的震动问题建立振动模型,探讨刹车振动行为及机制。最后基于ADAMS平台进行仿真,得到一些有益的结果,对于车辆行驶与路桥损害的进一步研究有参考作用。The paper makes an investigation on problem of a vehicle5 s sliding downon a slope bridge. It first setsu padynamic model and makes an analysis on the loads exerted on avehicle, and then sets up amodel ofvibration to the vibration caused by braking the vehicle. Detail mechanism of the braking-vibration is peered. Inthe end , simulations on ADAMS are made and also presents som e valuable results for studying the damagescaused by avehicle’s sliding down . Study of this paper is auseful reference to a deep study to damages to roadsand bridges on which vehicles run.
