Analysis of the Vehicle-Track-Bridge Interaction by Using Vector Form Intrinsic Finite Element

The main object of this research is to apply the vector form intrinsic finite element(VFIFE, V-5) method to calculate the nonlinear dynamic response of bridge under the vehicle. The VFIFE method is used to simulate the vehicle, the track and the bridge. The VFIFE method can be used to compute the motion of rigid body and deformable body ofthe vehicle. In addition, it does not require any iteration or change of parameters during computation for solving the problems. In this paper, the VFIFE method provided an effective numerical method for the vehicle-track-bridge interaction behaviors and a train derailment.
