摘　　要：运用SIMPACK的轮轨模块,建立城市轨道车辆的多体动力学模型,对车辆在不同速度和不同轨道不平顺激励条件下的脱轨安全性进行分析。仿真结果表明,城市轨道车辆在运行过程中,垂向的长波不平顺对车辆的扰动较大,容易造成车辆的安全事故;现有的城市轨道车辆脱轨安全标准比较保守,在分析车辆的脱轨安全性时,可以采用欧洲UIC规范对脱轨系数以每2m平均处理,避免脱轨系数峰值的影响,或者利用Weinstock准则进行辅助评判。The wheel/rail module of SIMAPCK is used to build a multi-body dynamics model of urban rail vehicle, and the derailment safety of vehicle is analyzed at different speeds and excitations. The simulation results show that the vertical long-wave excitation affects the vehicle stronger than other cases during the running, which is easily resulted in an accident, and the present derailment safety standard of urban rail vehicle is somewhat conservative. When analy- zing the derailment safety of vehicle, the European UIC Standard could be used, in which the derailment coefficient is an average value of 2 meters, designed to avoid the influ-ence of derailment coefficient peak, and the Weinstock norm is also helpful in safety iudgment.
