【摘要】 文章从分析列车气动阻力入手 ,结合现有试验数据 ,建立了我国铁路货车、客车及机车的单位基本阻力系列试用公式。经与《列车牵引计算规程》公式以及国外相关公式进行比较后 ,认为这种分析 -试验型公式比纯试验型公式更为合理而有效。此外 ,作者还提出加强列车牵引理论和应用的基础性研究等建议。更多还原

【Abstract】 By analysing train aerodynamic drag and considering existing experiment data,the paper sets the series trial formulas of unit basic resistance for railway freight cars,passenger cars and locomotives in China.Compared with the formulas of Chinese [RRTTC] and related foreign ones,the authors believe that analysis test type of train resistance formulas is more rational and effective than the pure test type.In addition,several suggestions,including emphasis on the basic research on railway train traction in theory and application are made.更多还原
