Influence analysis of train speed on vibration responses of footbridge

摘要

Influence analysis of train speed on vibration responses of footbridge entrance to platform induced by wind pressure due to main line train have been researched in the paper. With some footbridge as the research background, different wind pressure produced by different train speed acting on the bridge surface simulated by CFD method has been adopted to the bridge, thus influence of train speed on vibration responses of footbridge induced by wind due to main line train are obtained. Simulating results show that the vibration responses of footbridge entrance to platform intense with the increase of train speed.
