To study the effect of differential subgrade settlement on the potential damage of ballastless track and the dynamic response of high-speed trains, based on the concrete plastic damage theory, a vehicle-ballastless track-subgrade coupling dynamic model that considers the ballastless track bed damage is established. The applicability of the model is demonstrated by comparing with the calculation results of the linear elastic model. The effects of subgrade settlement wavelength, amplitude and the vehicle speed on the dynamic characteristics of high-speed trains are analyzed. The results show that, the differential subgrade settlement could cause the damage to ballatless track bed. The results of the concrete plastic damage model of ballastless track are more in line with actual service status of the track. Among the vehicle dynamics indicators, the vertical acceleration of the vehicle body is most affected by the subgrade settlement amplitude. The vehicle dynamics response is sensitive to the differential subgrade settlement with a wavelength below 20 m, so it should be paid more attention to. The increase of the train speed increases the dynamic response of the vehicle, the wheel-rail force increases significantly, and the vehicle stability index shows a nearly linear growth trend.
