 Abstract:

The main purpose of this study is to present a new approach for analyzing the dynamic response of bridge-vehicle interaction considering effects of sudden heavy braking force. The interaction between the bridge and vehicle is described by three phases which show quite agree with the real natural response of the moving vehicle, including before braking phases, sudden heavy braking phase and after braking phase. Especially, in the second phase, the vehicle can even stop in a short the time to the time t2 and the sliding of the wheel also can even occur in this case. From the three above phases, the governing equation of the motion of the bridge-vehicle interaction was established based on the finite element method and dynamic balance principle. And then, the influence of characteristic parameters of the bridge and moving vehicle on the dynamic response of the bridge-vehicle interaction was analyzed detail. The numerical investigation results showed that the new approach for bridge-vehicle interaction is the more increasing dynamic response of the bridge and moving vehicle than previous approaches. It can be seen that the study has meaning practice and it quite agrees to describe the true behavior of structure-vehicle interaction.
