摘要
时速400 km的高铁仍处于设计阶段,通过列车运行仿真对给定线路和信号设计方案下的通过能力及其他技术经济指标进行准确评价,有助于提高设计方案的合理性。本文分析了既有高速铁路列车运行仿真软件的功能不足,结合高铁设计对列车运行仿真的要求,设计出一款时速400 km高铁线路信号布局能力检算仿真系统。最后,基于既有高铁线路,利用该仿真系统对比分析了400 km/h动车组与350 km/h动车组在区间运行时分、牵引能耗和通过能力等方面的差异。
The 400 km/h high-speed rail is still in the design stage. Through train operation simulation, the passing capacity and other technical and economic indicators under a given line and signal design plan are accurately evaluated, which helps to improve the rationality of the design plan. This paper analyzes the functional deficiencies of the existing high-speed railway train operation simulation software, and combines the requirements of high-speed railway design for train operation simulation, and designs a 400 km/h high-speed railway line signal layout capacity check simulation system. Finally, based on the existing high-speed rail lines, the simulation system is used to compare and analyze the differences in running time, traction energy consumption and passing capacity of 400 km/h electric multiple unit (EMU) and 350 km/h EMU.
