摘要
应用相似理论,选用金龙XML6402汽车,在KDCG-10G和KDCG-3测功机台架上以及实际道路进行滑行距离的对比试验,研究确定了底盘测功机本身的惯性质量和车辆平移质量之比对车辆在台架上滑行距离的影响,获得试验车辆在两种台架上的修正参数分别为0.043和0.053,建立了在室内台架检测车辆滑行距离的修正模型。
Taking Kinglong XML6402 as testing vehicle, the experiment of its coasvdown distance on the bench of KDCG-10G and KDCG-3 dynamometers is carried out, and the experimental datum are compared with the one that are obtained from the real road test. The influence of the ratio of dynamometer inertia mass to vehicle moving mass on vehicle＇s coast-down distance is studied with similarity theory. The revision parameters of the test vehicle on the two kind of bench are respectively 0. 043 and 0. 053, so the revision model of coast-down distance is developed. 1 tab, 1 fig, 6 refs.
