| 摘 要： | 首先基于TR磁浮车辆,轨道梁及桥梁等建模方法建立起高速磁浮车辆-轨道梁-桥梁统一模型,在此基础之上编写计算机仿真程序,最后进行仿真计算和分析。对不同列车编组作用下桥上轨道梁的竖向振动和车体加速度进行了研究,结果发现列车编组对桥梁的振动和乘坐舒适性产生了一定的影响。通过改善列车编组的方法可以提高车桥耦合振动中车辆的动态性能。

| Abstract: | An integrated dynamic model of maglev vehicle-guideway-bridge coupling system was established based on TR maglev vehicle, the guideway and bridge technology firstly. Then, a special simulation program was developed. Finally, the vertical vibration of the guideway on bridge and the car body was studied under different train formations. The results show that the train formation has effect on guideway vibration and ride comfort to some degree. The dynamic performance of the train can be improved by reforming the train formation. |
