摘要

为探究新型磁浮列车的动力学特性，利用SIMPACK软件建立了其56自由度的中低速磁浮车辆模型并进行相关仿真分析，并采用单悬浮架模型进行了乘坐舒适性试验验证。仿真结果表明：新型磁浮列车能够实现140km/h在直线段稳定运行，车体横向加速度小于0.2m/s2，车体垂向加速度小于0.5m/s2，空载情况下能够实现30km/h通过半径为50m的弯道，车辆最大侧滚角不足0.04rad，车体最大横向加速度小于1m/s2，车体垂向加速度小于0.1m/s2，悬浮间隙动态变化量最大仅为0.5mm。试验结果表明：以140km/h的速度运行，与乘坐舒适性密切相关的车体垂向加速度约为0.5m/s2。

Abstract

To explore the dynamic characteristics of the new type of maglev train, a new model with 56 degrees of freedom was established and simulated, and a single suspension frame model was used as a test rig for ride comfort. The simulation results show that the new type of maglev train can be stable operation at the speed of 140km/h on the straight line; Lateral acceleration of car body is less than 0.2 m/s2; vertical acceleration of car body is less than 0.5m/s2; the new type of maglev train can stably pass through the curve with the radius of 50m at the speed of 30km/h; the largest car body roll Angle is less than 0.04 rad; lateral acceleration of car body is less than 1m/s2; vertical acceleration of car body is less than 0.1m/s2; dynamic variation of levitation clearance is only 0.5mm. The test results show that car body vertical acceleration related to ride comfort is about 0.5m/s2 at the speed of 140km/h.
