摘　　要：仿真是分析不同场景下列车运行动态特性最经济、高效、灵活的研究范式。为此引入元胞自动机理论,在准移动闭塞模式下,结合铁路区间线路、车站设施特点,构建固定设备元胞模型,基于此分析高速列车速度、位置更新规则,搭建高铁列车运行仿真框架。选取典型高铁线路,模拟正常运行、区间临时限速及车站股道故障三种场景,并完整记录仿真过程中车站、列车、信号等设备数据。通过绘制列车实绩运行图、速度-时间-位置图、列车累计晚点时间图,分析不同场景下列车运行规律。结果表明:仿真结果与该线路实际运行情况基本相符,模型可客观合理地再现高铁列车运行动态特性,且在模拟车站内不同作业类型列车进路冲突疏解过程提出创新,使仿真更贴合实际。Simulation is the most economical,efficient,and flexible research paradigm to analyze the dynamic characteristics of train operation under different scenarios.To this end,the cellular automata theory is introduced to construct a fixed equipment cellular model in quasi-mobile occlusion mode,combining the characteristics of railroad interval lines and station facilities,based on which the speed and position update rules of high-speed trains are analyzed and the simulation framework of high-speed train operation is built.Typical high-speed railway lines are selected to simulate three scenarios of normal operation,the temporary speed limit in the interval and station stock failure,and complete records of the station,train,and signal equipment data during the simulation.By drawing the actual train operation diagram,speed-time-position diagram and cumulative late train time diagram,the train operation laws under different scenarios are analyzed.The results show that the simulation results are basically consistent with the actual operation of the line,the model can objectively and reasonably reproduce the dynamic characteristics of high-speed train operation,and the innovation is proposed in the process of simulating the conflict resolution of different operation types of train approaches in the station,which makes the simulation more suitable for the actual situation.
