摘　　要：随着中国高速铁路、重载铁路的发展,特大型铁路桥梁结构不断涌现,其上的轨道结构千变万化,综合考虑车辆、轨道和桥梁结构的动力学仿真分析已成为轨道以及桥梁结构设计中极为重要的环节。文章结合有限元方法与车辆-轨道耦合动力学,基于C/S架构,通过网络通讯接口,建立车辆-轨道-桥梁相互作用分布式仿真平台。并分别使用该仿真平台与BANSYS软件仿真平台对韩家沱长江大桥进行车-线-桥系统的动力学仿真和对比,结果表明:该仿真平台在车辆各部件的振动响应分析、轨道结构的力学响应分析以及各项安全性指标等方面均能提供准确可靠的分析。With the rapid development of high-speed and heavy haul railway, some oversize railway bridge structures are emerging, and the track structure is also ever- changing. The comprehensive consideration of dynamic simulation analysis of the vehicle, track and bridge has become a very important part in the design of the track and bridge structure. Combined the finite element method with the theory of vehicle-track coupling dynamics, the train- track-bridge interaction distributed simulation platform is established based on C/S framework and through network communication interface, and by respectively using this simulation platform and the BANSYS software simulation platform, the dynamic simulation and comparison of the vehicle track bridge system of Hanjiatuo Changjiang River Bridge is conducted. The comparison results show that the simulation platform can provide accurate and reliable analysis in the vibration response analysis of the vehicle components, the mechanical response analysis of the track structure and the various safety indexes.
