| 摘 要： | 我国高速铁路与重载铁路发展迅速,尤其高速铁路与高速列车的数量与品质已居世界前列,所以界定高速列车与重载列车一些有歧见的牵引计算参数非常重要。依据分析与研讨结果,3个相关的牵引计算参数(回转质量系数、牵引力使用系数及保有加速度)的界定值已经得出并予以推荐:(1)我国高速列车(含空货物列车)的回转质量系数应取定为0.10,重载列车的回转质量系数仍维持0.06,相关的列车运行时间和距离的计算公式见表3;(2)对于高速与重载列车而言,牵引力使用系数完全没有必要;(3)高速列车与重载列车以及其他列车保有加速度可按表6选用,对于最高速度360 km/h及其以上的高速与超高速列车保有加速度(计入回转质量系数)可降至0.04 m/s2左右,而重载列车的保有加速度至少要选用0.01 m/s2。
