摘要：
This paper is to analyze the vehicle-bridge interaction system based on finite element method (FEM). The vehicle is studied as finite element model as well as the bridge, therefore the complex dynamic equations of vehicle Usually adopted is avoided here. Considering the longitudinal grade of bridge, the friction force is introduced to overcome the gravity component of vehicle along the slope. These forces along the slope will cause a moment on the vehicle body, changing the tire loads, and affecting the dynamic response of bridge. The result of numerical analysis is compared with measured data in the experiment, which validates the current method. Then the effects of the longitudinal grade on the dynamic response are discussed in several numerical cases.
