运用桥梁结构动力学与车辆动力学的研究方法，将车桥作为联合动力体系，以一座跨径布置为１４４＋ １９２＋ ２６４＋ １９２＋ １４４ｍ 的连续拱桁组合钢桁梁桥为研究对象，对高速列车过桥时的空间振动响应进行了分析，着重研究了列车速度变化时对桥梁的挠度、车辆舒适度及脱轨安全度的影响，并对列车运行走行性进行了评价。
Using the research methods of bridge structure dynamics and vehicle dynamics, the axle was taken as the joint dynamic system. Taking a series of continuous steel truss girder bridges with span of 144+ 192+ 264+ 192+ 144m as the research object, The space vibration response is analyzed. The influence of the train speed on the deflection of the bridge, the comfort of the vehicle and the safety of the derailment are studied emphatically. The running performance of the train is also evaluated.
