基于指定到达追踪间隔的高铁车站接车进路长度研究

确定合理的高铁车站接车进路长度对压缩到达追踪间隔时间有重要意义。本文首先通过构建满足到达追踪间隔时间的高铁车站接车进路长度计算模型,提出了接车进路长度的主要影响因素为由线路限制速度、站前坡坡度、制动力使用系数三因素(简称三因素)所确定的车载设备监控制动距离内列车运行时间。然后,通过对常见的线路限制速度、站前坡坡度、制动力使用系数取值下的车载设备监控制动距离内列车运行时间进行牵引计算仿真,并运用三因素方差分析法分析了三因素的影响显著度,得到了线路限制速度、站前坡坡度对高铁车站接车进路长度影响显著的结论。最后,基于高铁车站接车进路长度计算模型,得到了一组指定到达追踪间隔下的高铁车站接车进路长度表,为高铁车站设计提供思路。

On the Length of Receiving Route of High-Speed Railway Station Based on Specified Train Arrival Tracking Interval

It is important to determine the reasonable length of receiving route for high-speed railway station to reduce the arrival tracking interval time.In this paper,firstly,by constructing the calculation model of receiving route length in high-speed railway station to meet the arrival tracking interval time,it is proposed that the main influencing factors of receiving route length are the train running time within the braking distance monitored by on-board equipment,which are determined by three factors,namely,the line limited speed,the slope gradient in front of the station,and the braking force utilization coefficient.Then,through the traction calculation and Simulation of the train running time within the braking distance monitored by the onboard equipment under the common line speed limit,the slope gradient in front of the station and the braking force utilization coefficient,the influence significance of the three factors is analyzed by using the three factor analysis of variance,and the conclusion is drawn that the line speed limit and the slope gradient in front of the station have significant influence on the length of the receiving route of the high-speed railway station.Finally,according to the calculation model of receiving route length of high-speed railway station,obtaining a set of receiving route length table of high-speed railway station under specified arrival tracking interval is obtained,which provides ideas for the design of high-speed railway station.
