Accordingly, the train running safety and stability are more affected by increased dynamic stresses. High Speed Railway Track Dynamics lays a good foundation for investigating the complicated wheel-rail relationship and interaction mecha

Studies have shown that when train speed reaches or exceeds some critical velocities, there would be surface waves induced by high speed trains causing strong vibration of the track structure. In order to study the mechanism of the s
