| Summary: | 碩士 === 中原大學 === 土木工程研究所 === 100 === In this study, the main purpose is to develop a numerical program of three-dimension train-rail-bridge interaction simulation. This program can be used to simulate the motion vehicle on the rail-bridge. It is important for the simulation method of the motion vehicle, and the vehicle model represents the rigid bodies and spring elements using vector form intrinsic finite element (VFIFE, V-5). This method and model are the core technology. In addition, the pre-processor and post-processor are developed. In this study, the vehicle model is characterized by the program user can use arbitrarily shape for rigid body and easily build the vehicle suspension systems. The displacement control (DC) for wheels. According to the numerical results, it confirms the effective and accurate of this numerical program.
