摘要
结合车辆系统动力学理论,通过SIMPACK软件建立了包含空气弹簧特性的动力学模型,分析了空气弹簧失效后车辆系统的稳定性以及空气弹簧失效对地铁车辆动力学性能的影响,并提出了相应的建议。
In combination of the vehicle system dynamics theory,the dynamics model including features of air springs is set up with the SIMPACK software.Thestability of the vehicle system after failure of air springs as well as the effect of failure of air springs on the dynamics performance of metro vehicles is analyzed.And corresponding suggestions are given.
