An Investigation Into the Vehicle-Curved Bridge Dynamic Interaction

Moving vehicle dynamics is studied while travelling on a curved bridge in this paper. The vehicle including the driver and the passenger is simulated as a half-car planner model having six degrees of freedom, travelling on the bridge with constant velocity. The bridge is modeled as a curved beam that obeys the Timoshenko beam theory. Finite element method is employed to solve the combinational problem. The obtained numerical results are compared with those reported in the literature in a number of special cases. A parametric study is then carried out and effects of different parameters on both the vehicle and bridge dynamic behavior are investigated.
