汽车道路滑行阻力的研究

Research on Vehicle Road Coast Down Resistance

基于汽车道路滑行原理,建立汽车道路滑行阻力的计算模型,分别对车辆不同状态进行道路滑行试验,得到滑行阻力曲线,分析影响车辆滑行阻力的主要因素,对比了滑行法和标准查表法得到的阻力曲线,结果显示滑行法得到的道路阻力更能真实反映车辆道路行驶实际情况。

Based on the principle of vehicle road coast down,the calculation model of vehicle road coast down resistance is established.The road coast down resistance curves are obtained through the road coast down tests of different vehicle states,and the main factors affecting vehicle coast down resistance are analyzed.The resistance curves obtained by coast down method and standard look-up table method are compared.The results show that the road resistance obtained by taxiing method can more truly reflect vehicle road driving.Physical truth.
