,Model for Vertical Dynamic Analysis of the Vehicle–Track–Subgrade–Ground Coupling System,effects of subgrade and ground have not been considered and the subgrade is simplified into viscoelastic damping elements. In fact, an accurate analysis of the vehicle dynamic action on the track structure has to consider the interactions among the vehicle, the track, the subgrade and the ground. In
