基于轻型车国六标准和国五标准下的道路滑行阻力比对研究

Comparative Study of Road Sliding Resistance based on the NationalⅥStandards and NationalⅤStandards for Light Vehicles

阐述了乘用车道路滑行的工作原理,比较了基于轻型车国六标准的道路滑行法(简称国六滑行法)和基于国五标准的道路滑行法(简称国五滑行法)在阻力模型建立、滑行时间计算和试验结果修正等方面的差异,并开展了实车验证。理论和实践表明,国六滑行法比国五滑行法阻力大。

The article explains the working principle of passenger car road taxiing,and compares the differences in resistance,in model establishment,and taxi time calculation,based on the road taxiing method based on the nationalⅥstandards for light vehicles(referred to as the national six taxiing method)and the road taxiing method based on the national five standards(referred to as the national five taxiing method).And the test results revision are carried out to verify the actual vehicle.Theory and practice have shown that the NationalⅥsliding method has greater resistance than the NationalⅤsliding method.
