Motion analysis of the derailed carriage 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 vehicle model using frame element is used to compute the motion of the vehicle. The VFIFE method also can be used to simulate the deformation of the rail and the bridge. In addition, it can't require any iteration or any 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. Two numerical example is to demonstrate the capability and accuracy of the VFIFE method.
