This investigation draws on the expertise of urban rail transit vibration damping track, based on the theory of vehicle-track coupling dynamics, systematically studied the impact of the change in the stiffness of the damping fastener on the vehicle when the 200 km/h high-speed railway track adopts fastener-type damping measures. And the influence law of the dynamic response evaluation index of the track system; the usability of the stiffness value of the typical vibration damping fastener of urban rail transit in the high-speed railway is evaluated; the reasonable value range of the stiffness parameter of the high-speed railway vibration damping track is proposed. Studies have shown that when rails with fasteners are used in high-speed railways, their stiffness should not be lower than 15 kN/mm. Although they have a certain suppression effect on environmental vibration, their vibration reduction effects are much lower than those of urban rail transit fasteners. The damping effect of the damping measures.
