基于底盘测功机的整车性能衰退研究

Research on the performance decline of the whole vehicle based on chassis dynamometer

汽车在行驶一定里程后其性能会发生一定的衰退,在底盘测功机上进行汽车性能对比试验能减少许多不可控的因素对试验结果的影响。通过在底盘测功机上对某卡车进行动力性、经济性试验,对比分析测量车辆在行驶不同公里数后的动力性、经济性试验结果,阐述底盘测功机在整车性能衰退研究上的应用。

The car will have a certain decline in the performance of a certain mileage.On the chassis dynamometer, it can reduce the influence of many uncontrollable factors on the experimental results.By the power and economy test of a truck on a chassis dynamometer and comparative analysis of the test results of the dynamic and economic performance of the vehicle at different km driving force to application of chassis dynamometer in the research of vehicle performance decline.
