摘　　要：在株洲低速EMS磁浮试验线实验中发现,磁浮列车上下坡时经过有坡度的轨道,容易出现砸轨现象,严重影响了车辆的安全性和舒适性。为研究这一问题,建立了具有4个自由度的低速EMS型磁浮列车单节车厢-轨道动力学模型,仿真分析了在不同车-轨条件下,车辆上坡过程中的动力学行为。仿真结果表明,车辆参数、车辆速度、轨道坡度都会影响车辆通过时的稳定性;轨道采用缓和曲线能减少车辆受到的冲击。在磁浮系统轨道线路设计中应该综合考虑系统多个参数之间的关系。此研究结果对于完善EMS磁浮系统车辆设计、轨道线路规划方面具有一定的参考价值。In the low speed EMS maglev test line experiments in Zhuzhou, it was found that vehicles are prone to hit the tracks, when the maglev train travels uphill or downhill through the tracks with slopes. This seriously affected the safety and comfort of the vehicle. In order to study the problem, a single low speed EMS maglev train carriages-track model with four degrees of freedom was built. It simulated and analyzed dynamic behaviors of the vehicle going uphill on different track curves, under different vehicle-track parameters. The simulation results show that the vehicle parameters, vehicle speed, and the rail slope will affect the stability of the vehicle through; using transition curves in tracks can reduce the impacts on vehicles. In the design of maglev system, the relationship between the parameters of the system should be considered. The study has a certain valuable as reference for improving the design of EMS maglev vehicle system and the planning of the track routes.
