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。China＇s high speed railway and heavy haul railway are developing rapidly,especially the high speed railway and high speed train are standing in the world forefront by both quantity and guality,so the determination of several different meaning＇s traction calculation parameters for high speed train and heavy haul train is highly important.In accordance with the results of analysis and discussion,the determinative values of three correlative traction calculation parameters（rotary mass coefficient,exploited tractive effort coefficient and holding acceleration） are made and suggested： 1st,the rotary mass coefficient of China＇s high speed train（including empty freight train） should be selected to 0.10,and the rotary mass coefficient of heavy haul train is reserved to 0.06 also,the correspending computational formulas for train operation time and distance can be used by list 3;2nd,the exploited tractive effort coefficient is unnecessary absoluted for high speed train and heavy haul train;3rd,the holding acceleration of high speed train and heavy haul train and other kinds train may be selected by list 6,when the top speed vmax≥360 km/h,the holding acceleration of high speed and super high speed train may be lowered to about 0.04 m/s2,but the holding acceleration of heavy haul train should be selected to 0.01 m/s2 at least.
