列车进站提前减速初探

Train Pre-decelerating Before Arrival Station

在我国客运专线采用目标-距离模式曲线速度控制方式的前提下,按照传统确定列车到站间隔的原则所得的到站时间将不能满足高密度的行车需求,为此,国内有关专家提出列车提前减速的方法减小列车到站间隔,但未形成系统的计算体系。基于此,本文根据到站追踪间隔时间的形成机理,分析提前减速减小到站间隔时间的可行性,在阐明提前减速内在本质的基础上,提出相应到站间隔计算方法,并利用模拟的方法,结合实例验证了方法的正确性、实用性。

Under the premise of using the target-distance speed control system in passenger transportation, arrival time that is determined by the traditional methodwill not be able to satisfy the demand of high density transportation. Some experts have found that pre-decelerating can solve this problem, but a systematic computing method is not formed.According to the mechanism of arrival interval, this article analyzed the possibility of reducing headway time in station when it use pre-decelerating, the essence of pre-braking is expatiated, and akindof relevant calculation way is also given. Then, it＇ s correctness and practicability were testified by an example by computer simulating.
