| Abstract: | 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. |
