摘要
车辆在良好水平路面以最大速度Ｖｍａｘ行驶时的最小滚动阻力系数，是设计和试验的重要选择数据和评价依据． 如何确切地选择这个指标， 既要有理论分析， 更要有试验数据的统计分析． 该文根据国内外２０ 种高速履带车辆的统计数据和试验数据， 进行了统计分析， 提出可行的推荐范围， 可供设计参考． 此外， 对沿用多年的行动部分效率经验计算式作了一定评述， 对不确切的动力因素术语提出改正．
When vehicle running at maximum speed on good level road,its minimum rolling resistance factor is the important selecting data and evaluating basis for design and test.How to select the index exactly,it needs not only the theoretical analyses,but also the statistical analysis of test data.In this paper,statistical test data have been statistically analyzed about twenty kinds of high speed tracked vehicles at home and abroad.The practical scope recommened is proposed for design reference.Additionally,the moving system efficiency formula used for many years has been discussed at certain level.A correction about some unexact technical term of power factor is proposed.
