Dynamic Response of a Timoshenko Beam Subjected to a Moving Vehicle with 6 D.O.Fs

The dynamic response of a bridge due to a traveling vehicle has been considered. The vehicle is modeled as a half-car-planar with six degrees-of-freedom, and the bridge has been assumed to obey the Timoshenko beam theory with simply supported boundary conditions. It is assumed that the vehicle moves with constant velocity. Based on Hamilton's principle, this problem was analyzed using modified beam vibration functions as he assumed mode. The results of half car planar model for Euler-Bernoulli and Timoshenko beams were compared with together. Comparing the results demonstrates that the maximum dynamic deflection occurs at the vicinity of the bridge mid-span.
