,Vehicle–Track Coupled Dynamics Models, vehicle–track coupled systems are discussed at first. And then, three types of theoretical models are established: the vehicle–track vertically coupled dynamics model, the vehicle–track spatially coupled dynamics model, and the train–track spatially coupled dynamics model, in which typical passenge
