摘　　要：通过研究多种车型的道路滑行阻力系数,为阻力系数外推提供改进的方向,从而达到阻力系数优化的目的。对试验场多年积累的滑行数据进行研究,归纳总结出3种车型滑行阻力系数数据,分析试验质量、迎风面积对阻力系数的影响,并外推出一种计算阻力系数的数学方法,以提高滑行试验的效率,满足企业排放试验需求。By studying the road coasting resistance coefficients of several vehicle models,improvement direction could be provide for the extrapolation of resistance coefficients,thereby achieving the goal of optimizing resistance coefficients.The coasting test data accumulated over the years in the test ground was studied,and the coasting resistance coefficients data of three vehicle models were summarized.The influence of test mass and vehicle frontal area on the resistance coefficients was analyzed,and a mathematical method for calculating the resistance coefficients was extrapolated to improve the efficiency of sliding tests and meet the emission testing needs of enterprises.
