摘要
分析了铁路轨道高低不平顺的预测原理,用轮轨动力分析方法确定了满足安全和舒适要求下的高低不平顺发展容许值,并与快速线路维修新规则管理标准作了比较,结果基本相符。以沪宁线为实例,对不同条件下高低不平顺发展作了参数分析。
This paper briefly analyzed the principle of the prediction of track vertical profile irregularity,determined its permissible deviation value meetiong running safety and riding comfort by using wheel/rail dynamics analysis method,and compared it with the standard of the present maintaining rules.Numerical calculations indicate that the result of prediction is effective and basically accurate.Taking the Huning railway as an example,we predicted the development of vertical profile irregularity,and analyzed the parameters of the Huning railway.
