| 摘 要： | 利用三角级数法模拟了轨道的不平顺，采用列车编组和桥梁组合的模型，建立了车桥耦合振动方程。对不同列车编组作用下桥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影响很大。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: | By simulating the track irregularities with trigonometric series method, the train -bridge coupling vibration equations are established based on the combined modal of train formation and the bridge. Then the vertical vibration of the bridge and the car - body acceleration are studied under different train formations. The results show that the train formation has great effect on bridge vibration and riding comfort. The dynamic performance of the train can be improved by reforming the train formation. |
