说明：  关于车辆与桥梁的振动问题，主要是车辆动力系统与桥梁动力系统之间的耦合振动问题。车辆以一定的速度在桥上运行，会使桥体产生振动，同时车辆的振动也会使桥体产生振动。桥也会影响车辆的振动。这种相互影响、相互作用的问题，就是车辆与桥梁之间的耦合振动问题。我们用MATLAB写出根据Newmark-beta方法的代码来处理耦合方程。(The vibration of the vehicle and bridge is mainly the coupling vibration between the vehicle power system and the bridge dynamic system. The vehicle running on the bridge at a certain speed will make the bridge vibrate, and the vibration of the vehicle will also make the bridge vibrate. Bridges can also affect the vibration of vehicles. This interaction problem is the coupling vibration between vehicle and bridge. We use Matlab to write the code according to the Newmark beta method to deal with the coupling equation.)
