摘要
针对160 km/h动力集中型动车组推挽式运行的安全性问题,利用SIMPACK建立动车组9编组动力学模型。仿真分析了不同牵引方式下动车组的安全性。对动车组的直线运行安全性及平稳性,横风环境下运行的安全性做了分析,并将推挽式运行与牵引式运行时的安全性和平稳性进行了对比分析。结果表明,对于推行的特殊工况,安全性指标与正常运行时相差不大,平稳性指标有所增大,但都满足运行要求。在横风风速为30 m/s时,动车组推挽式运行的最高允许运行速度为156.7 km/h,比牵引式运行时最高允许运行速度降低了20%,动车组推挽式运行时抵御横风的能力明显下降。
In view of the safety problem of 160 km/h concentrated power EMU in push-pull operation,a software named SIMPACK was used to build the dynamic model of EMU.Simulation analysis of safety on EMU was conducted in different traction modes.The safety and stability of its straight line running and the running under crosswind were analyzed,then the safety and stability of push-pull operation and traction operation were analyzed.The results show that,for the special conditions of push-pull operation,there is almost no difference of safety indexes with traction operation,and a certain increase of stability indexes,which still meet the operational requirements.A maximum allowable run speed is 156.7 km/h at a crosswind speed of 30 m/s,which is 20%lower than the maximum allowable speed of traction operation.The ability to resist crosswind in push-pull condition is significantly reduced.
