Simulation Study on Anti-rolling Effect of Tail Grade and Stop Device Layout at Hump Shunting Yard

为提高铁路驼峰调车场尾部防溜安全性,阐述驼峰调车场尾部停车器布置现状及存在问题,针对调车场尾部线路坡度多样、停车防溜设备布置方案不同及溜放车辆随机变化的特点,设计驼峰调车场尾部防溜仿真系统及相关参数设置,通过对调车场线路有效长?850??m?和?1?050??m???2?种情况下不同线路尾部坡度和不同停车器布置方案进行仿真试验,得到尾部不同坡度和停车器布置的防溜方案,为驼峰调车场停车防溜系统的防溜效果验证和相关设计提供可靠的技术手段。

In order to increase anti-rolling safety at the tail of railway hump shunting yard,this paper summarizes both the status and problems of stop device layout at the tail area,targeting the characteristics of tail area,including diversified line grades,different layout stopping schemes for anti-rolling devices,and random change of rolling vehicles,a anti-rolling simulation system for tail of hump shunting yard and relative parameters are designed.Through making simulation test on the tail grade of different lines and different layout schemes of stopping device under 2 conditions（the effective length of line in shunting yard of 850 m and 1 050m）,the anti-rolling schemes of different tail grades and stopping device layout are achieved,so as to provide reliable technical approaches for the anti-rolling effect validation,and the relative design of stopping and anti-rolling system at hump shunting yard.
