摘要：
This paper presents the analysis of the three dimensional vehicle-track-bridge interaction (VTBI) behaviours by a new computational method called the Vector Form Intrinsic Finite Element (VFIFE) method that is capable to do the nonlinear large deformation analysis of structures. The particle dynamics algorithm within the VFIFE method does not require solving any VTBI parameters iteratively. Hence,it is capable to investigate versatile of nonlinear dynamic problems like the motion behaviours of carriages derailment failure with the large deformation and the dynamics of the vehicle-track-bridge system due to earthquake excitations. Numerical examples demonstre that the analysis method proposed in this study can effectively and accurately analyze the nonlinear, dynamic behaviours of the vehicle-track-bridge system.
