摘要

摘要:研究目的:驼峰设计规范中对于车辆溜放安全多从避免难易行车追钩撞车以及预防车辆高速连挂角度 考虑,较少考虑溜放过程中车辆行车性能所反映的溜车安全问题,且对溜放区纵断面采用先定峰高后定坡段 的设计方式,这不仅禁锢驼峰线形设计的灵活性,也限制溜车效率的提高。本文依托某驼峰溜放区实际线路 条件,通过进行车辆行车性能分析,在保证车辆溜放安全的基础上,以提高溜放效率为前提,对溜放区加速坡 坡长进行优化。研究结论:(1)既有规范中所规定的驼峰加速坡坡长足以保证车辆溜放安全;(2)既有规范中所规定的驼 峰加速坡坡长制约了车辆溜放速度的提高;(3)此研究可为驼峰设计中依据驼峰等级和地形条件增大加速坡 坡长选取范围以及提升驼峰下车辆的溜放效率提供参考。

Abstract

Abstract : Research purposes : The avoiding of hard rolling wagon colliding with easy rolling wagon and vehicle coupling at a high speed are considered in hump design specification,and the train operation performance and vehicle operation safety is neglected. At the same time, the method that designing slope after confirming hump height was proposed in hump design code not only confines the hump geometric design flexibility,but also limits the slide efficiency. Based on railway line parameters of a hump and train operation performance analysis, taking vehicle humping safety as the premise,length of the accelerate slope was optimized in this research. Research conclusions: (1) The regulated accelerate slope length in existing standard can ensure the humping safety. (2) The enhancement of vehicle humping speed is restricted for the regulated accelerate slope length in existing standard. (3) The selection slope can be increased suitably according to the hump level and the terrain conditions to enhance the humping efficiency of hump.
