In order to analyze the response and influencing factors from vehicle-bridge coupled vibration between curved continuous rigid frame bridge and whole vehicle model of 7 degrees of freedom, a spatial numerical analysis method of vehicle-bridge coupled vibration caused by bridge deck roughness was proposed. According to power spectrum density advised by GB/T 7031-2005, bridge deck roughness was simulated by the application of Fourier reverse transform. Because of delay of front and rear axles and correlation between left and right wheels, the roughness sequence of each wheel was obtained by the frequency response function solved by means of random vibration theory. The samples were taken as the input disturbances, rules of vehicle-bridge coupled vibration response under different grades of bridge deck were obtained using the finite element software ANSYS. Analysis results indicate that the value of dynamic coefficients of displacement and torsional angle increase sharply along with the grade increase of bridge deck roughness, and accurate simulation of bridge deck roughness is crucial for analyzing and evaluating the impact of vehicles on the bridge.
