| 摘 要： | 近年来,随着23 t轴重货车的应用,编组站在解体作业中出现驼峰偏高、超速连挂等不适应问题,降低峰高是编组站驼峰适应货车大型化发展的趋势.基于此,本文分析了驼峰设计的三难条件(难行车、难行气候、难行线),提出在驼峰选址及平面设计确定的条件下,车辆因素成为峰高设计的变化因素,并以此分析了既有驼峰设计规范中以总重30 t不满载关门窗的滑动轴承P50作为驼峰设计难行车的不合理性.在此基础上,给出了基于三难条件出现概率的难行车质量确定方法,并设置一定的三难条件出现概率,计算出相应的难行车质量,为峰高设计中难行车质量的确定提供参考.

| Abstract: | In recent years,with the application of 23 t axle load freight cars,the marshalling at the hump yard shows adaptability problems such as the higher hump height and coupling over-speed in disassembly work,the paper points out that lowering the hump's height is a trend to adapt hump with the larger size development of the freight car.Based on this,the three difficult conditions(hard rolling cars,difficult climate and difficult lines) in the design of hump is analyzed,and the factor of cars is considered to be... |
