高速铁路追踪列车间隔时间测试方法标准化研究

针对高速铁路追踪列车间隔时间测试没有标准化方法的现状,明确测试理论基础,规范测试方法。运用到达车站间隔时间的分析计算方法探讨高速铁路追踪列车间隔时间测试理论,提出高速铁路列车速度与密度合理匹配关系是追踪列车间隔时间测试的理论基础,计算结果符合我国高速铁路实际情况。指出司机操纵差异、咽喉长度、线路条件等是影响追踪列车间隔时间测试出现偏差的重要因素,从测试组织过程、测试结果以及结果的动态分析角度规范追踪列车间隔时间测试方法,方法可操作性较强,能够体现线路实际列车追踪运行能力,已应用于10余条高速铁路的运行试验工作。

Study on Method Standardization of High-speed Railway Tracking Train Interval Test

In view of the fact that there is no standardized method for high-speed railway tracking train interval test,this paper aims to define test theoretical basis and standardize test method. By analyzing and calculating the interval of trains arriving at the station,this paper holds that reasonable matching relationship of high-speed railway train speed with density is the theoretical basis for tracking train interval test and the manipulating differences in drivers,the throat length and the line conditions are important factors that may result in deviations during the test. The method for tracking test is standardized with respect to test organization,test results and dynamic analysis of results. The standardized method is proved applicable in reflecting practical train tracking ability of the line,and has been applied to more than 10 of the high-speed railways.
