摘要
线路条件是列车追踪间隔时间的主要影响因素之一。为探究线路条件对列车追踪间隔时间的影响机制,在阐述列车追踪间隔时间的计算方法与影响因素的基础上,分析得到线路附加阻力和因线路条件导致的限速运行是线路条件影响列车追踪间隔时间的2个方面,通过探讨线路附加阻力对追踪间隔时间的影响,推导出限速运行下的列车追踪过程与追踪间隔时间的计算方法,最后结合不同线路附加阻力与限速运行下的各类列车追踪间隔时间的检算结果,得到线路条件对列车追踪间隔时间的影响规律,为列车追踪间隔时间的优化以及线路的设计提供参考。
Line condition is one of the main factors influencing train tracking interval.In order to explore the influence mechanism of line condition on train tracking interval,based on the calculation method of train tracking interval and the analysis of influencing factors,line condition affects train tracking interval from two aspects,namely,the line additional resistance and speed limit operation caused by line condition.The influence of the line additional resistance on train tracking interval was theoretically analyzed,the tracking process and the calculation method of train tracking interval under speed limit operation were deduced.Considering the check-calculation results of various train tracking interval under different line additional resistance and speed limit operation,the influence law of line condition on train tracking interval was obtained,providing reference for the optimization of train tracking interval and the design of the line.
