高速铁路列车追踪间隔分析与仿真研究

Study on Analysis and Simulation of High-speed Railway Train Tracing Interval

由于受到很多条件变化的影响,目前铁路通过能力的计算方法在很多时候很难准确反映实际情况,因而利用仿真技术从微观角度分析高速铁路上动车组列车对线路的时空占用过程。在给定研究边界的基础上,分析列车单点占用、闭塞分区和接发车进路占用、安全占用及追踪占用的过程和计算公式,最后使用Open Track软件对不同编组形式动车组列车的单点占用、不同线路参数下的列车占用、列车安全占用及追踪占用过程进行仿真和分析,得出动车组列车在各种组合工况下的追踪间隔,以及低等级列车对高等级列车运行的影响程度。

For current calculation method of railway carrying capacity is influenced by change of many conditions and is difficulty to accurately reflect actual situation, so the space-time occupancy process of EMU train on high-speed railway line is analyzed from micro perspective by using simulation technology. Based on the provided research boundary, this paper analyzes the process and calculation formula of train single-point occupancy, occupancy of block section and train receiving-departure route, safety occupancy as well as tracing occupancy, in the end, the paper makes simulation and analysis on the process of single-point occupancy, train occupancy under different line parameters, train safety occupancy and tracing occupancy for EMU trains with different formation modes by using OpenTrack software, and then, the tracing interval of EMU trains under various combined conditions and the influence degree of low-class trains on operation of high-class trains are achieved.
