电分相设置对高速动车组运行速度及时分影响研究

摘要

The safety and efficiency of EMU （Electric Multiple Unit） operation is more and more important, and the influence on the EMUrunning speed ＆ time with auto-passing electric phrase separation is payed more attention. This paper focused on the influence on EMU running speed ＆ time with auto-passing electric phrase separation without electricity. By describing the micro-process of an EMU auto-passing the electric phase separation, an algorithm for the influence on EMUrunning speed ＆ time with setting electricity phase splitting was constructed and the influence under different conditions, such as different operating conditions, differentposition of the phases, different condition of the railway lines ,etc. were simulated. Some suggestions for the computation and location of the elecric phase splitting were put forward.%高速铁路对列车运行安全及运输效率的要求越来越高，电分相对列车运行速度和时间的影响逐步受到重视。本文重点研究采用不带电过分相方式对列车运行速度及时分的影响，通过描述动车组不带电自动电分相的微观过程，建立了电分相对速度及时分影响的算法，模拟计算了不同运行条件、不同设置位置和纵断面情况下电分相对列车速度及时分的影响，提出高速铁路电分相设置及检算原则，为高速铁路电分相设置提供一定参考。
