摘　　要：宽轨铁路增建二线成为孟加拉国既有线改造采用较多的方案,宽轨铁路增建二线后列车双向会车条件下系统动力响应问题的研究已显得十分必要。论文利用有限元软件ANSYS/LS-DYNA建立单、双线宽轨铁路车线动力学模型,仿真列车单向行车、双向等速会车运行过程,分析增建二线对既有线系统动力性能的影响,在此基础上研究运行速度与动力响应的关系,为宽轨铁路增建二线的设计及运营提供参考建议。Adding second line of broad-gauge railway is becoming a widely used scheme for existing railway reconstruction in Bangladesh. The study of system dynamic response under this condition is necessary. In this paper, single track and double tracks dynamic models of vehicle-track system are constructed by the finite element software ANSYS/LS-DYNA. The running process of a single train and two-way train are simulated and analyzed. Analyzing system dynamic performance impact of existing railway base on adding second line, On this basis, the relationship between running speed and dynamic response is studied, which provides some suggestions for design and operation of adding second line of broad-gauge railway.
