Study on Testing and Appraising Method of Vehicle Power Performance

研究了汽车动力性检测的功率损失状况 ,据此建立各部分的功率损失数学模型 ,分析影响动力性检测的主要因素 ,并以 BJ12 1型轻型载货汽车为例 。

Vehicle power performance may affect transport and security, so it must be detected in definite time. Chassis dynamometers are used by most national detecting station, the means is relatively exact and credible, but the classification of vehicle is often mistaken for no good method. On the basis of the research of testing experiments on power loss of automobile power performance in use, mathematical models of each part of power loss were developed in this paper. The influential factors of measuring automobile power performance were also analyzed. Taking a BJ121 truck as an example, the general appraisement method on test of automobile power performence was set up.
