中文摘要：

车桥耦合系统以车轮与桥面的接触点为界限,将车桥耦合整体系统划分为车辆系统和桥梁系统两个独立系统,建立车辆运动平衡方程与桥梁运动平衡方程,通过桥梁接触点的位移协调条件及车辆在桥面接触点产生的相互作用力进行将两者进行联系,将其联立即为车桥耦合运动平衡方程组,通过采用迭代法进行计算求出车桥耦合系统的振动响应。

英文摘要：

The vehicle-bridge system consists is two subsystems at the interface of the bridge and vehicle. Establishing the equations of motion for the bridge and the vehicles respectively, The dynamic responses of bridges are studied through numerical simulation method is presented to analyze the coupling vibration re- sponse of vehicle-bridge system based on the same displacement and coupling force at the interface.
