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 vehi

用matlab搭建的整车14自由度整车模型，模型可以运行，但是滑移率计算的地方存在一些问题，(The 14 degree of freedom vehicle model built by Matlab can run, but there are some problems in the calculation of slip ratio, which need to be solved)
