朔黄铁路2万t重载列车制动管压力波动原因分析

Cause analysis of brake pipe pressure fluctuation of 20000 ton heavy-duty train on Shuohuang railway

朔黄铁路西线龙宫站至北大牛站区段,连续出现2万t重载列车制动管压力异常变化现象,该问题导致重载列车制动力减弱或增强,严重干扰运输秩序。文章在列车上增加数据采集系统等装备,现场还原了2万t重载列车制动管压异常情况,通过分析试验数据对可能造成制动管压力波动的因素进行了探究。

In the section from Longgong Station to Beidniu Station of Shuohuang Railway,the pressure of 20000 tons of heavy-duty train changed continuously,which led to the weakening or enhancement of the braking force of the heavy-duty train,and seriously interfered with the transportation order.In this paper,data acquisition system and other equipment are added to the train,the abnormal pressure of the brake pipe of 20000 tons of heavy-duty train is restored on the spot,and the factors that may cause the fluctuation of the brake pipe pressure are explored through the analysis of test data.
