摘要
为了明确武汉轨道交通2号线过江隧道区间坡段对列车运行特性的影响,为运行方案设计提供理论依据,建立武汉轨道交通2号线过江隧道两列车在长大坡道上的动力学模型,展开两列车同轨道运行工况下正常运行和不同动力故障时相对运动的动态仿真,基于Simulink/Virtual Reality Toolbox,对两列车的相对运动实现可视化。结果表明,该分析揭示了隧道内复杂坡段对列车最大运行速度和发车间隔的影响,有效指导过江隧道复杂坡段列车运行的方案设计。
To clarify the influence of longitudinal slope sections in the under-river tunnel on the moving of trains and provide theoretical foundation for the operation design of trains, two trains running on the long and big slope sections in the tunnel in Wuhan rail transit Line 2 were modeled. Operation simulation of two trains＇ relative movement under normal and different power fault conditions was performed and visualized synchronously according to simulation results obtained by utilizing software Simulink/ Virtula Reality Toolbox. Results of the simulation analysis helped to reveal the influence of complicated slope sections in the tunnel on the operation maximum speed and departure intervals of trains and to guide the operation design option of trains moving on the complicated slope sections of the tunnel.
