Abstract: A fine spatial vehicle-pavement coupling vibration model was established to simulate the dynamic responses of rigid pavement under moving vehicle, in which the mass-spring-damper model was adopted for the vehicle and the finite element model based on the Winkler foundation was adopted for the concrete pavement. The improved harmonic superposition method was used to consider the 3-D distribution of road surface roughness, and the displacement coordination equation was used for the simultaneous solution of the vehicle and pavement vibration. Example analysis showed that the established vehiclepavement coupling vibration model could truly reflect the space geometric and mechanical coupling relationship between vehicle and pavement. With the stimulus of threedimensional road roughness, the dynamic response of the vehicle and pavement showed significant spatial distribution characteristics. Comparing with the results of the transient dynamic analysis method, the deflection and stress of the pavement significantly increased.
