摘　　要：通过研究底盘测功机台架与实际道路的滚动阻力之间存在的差异,以及对车轮在台架上滚动阻力的分析,建立了车辆台架检测滚动阻力修正模型。以某型汽车为例,对该模型进行了台架对比试验验证。利用该模型求得检测车辆在任意滚筒直径的底盘测功机上的加载功率,其精度满足测功机检测规程中的规定。By studying the difference of rolling resistance between chassis dynamometer bench and road, and analyzing the rolling resistance of wheels on bench, a revising model to test rolling resistance of vehicle bench is built. The paper takes a vehicle as example to compare and test the model with stand. With the aid of this model, loading power of the tested vehicle on the chassis dynamometer with random barrel diameter is obtained with accuracy in compliance with the requirement of dynamometer test regulation.
