摘要

牵引质量是指机车牵引普通货物列车的总吨数。川藏铁路地形地势特殊、坡度陡长,具有明显的高寒山区长大坡道的特点。考虑川藏铁路的特殊影响因素,在基于2.4%和3.0%两个限坡比较系列上从列车起动、到发线有效长、车钩强度、电机温升、黏着系数等方面的情况下,确定列车牵引质量及牵引组配方案。研究得出,为更好地适应地形条件,推荐在2.4%限坡上正常天气情况下采用HXD_2双机牵引3000 t、雨雪天气牵引质量2800 t;在3.0%限坡上正常天气情况下采用HXD_2双机牵引2700t、雨雪天气牵引质量2200t。
Traction quality refers to the locomotive traction tonnage of general freight train.The characteristics of the Chengdu-Lhasa railway are terrain special,long slope steep,Has the obvious characteristics of alpine region grow up ramps.Considering special influence factors of Chengdu-Lhasa railway,comparison and selection between two schemes are made,one with gradient of 24‰ and the other is 30‰,based on these basis,from the train start,departure line,coupling intensity factors,the motor temperature rise,adhesion coefficient,etc,Determine thetraction quality and some arrangement plan;Study to better adapt to the terrain conditions,recommended on the gradient of 24‰ using double HXD_2 traction 3000t(The normal weather)or using double HXD_2 traction 2800t(The Rain and snow weather);recommended on the gradient of 30‰ using double HXD_2traction 2700t(The normalweather)or using double HXD_2 traction 2200t(The Rain and snow weather).
