部分负载测功法的试验研究

汽车维修使用部门测试功率，常使用底盘测功机或无负载加速测功法。前者造价高、后者存在未知转动惯量及测量精度问题，未能普及。该文提出一种部分负载测功法，较好地解决了加速测功法的固有缺陷，又保持了造价低的优点，便于维修部门使用。

Study on Vehicle Power Measurement Using Partial Load Acceleration

In vehicle maintenance works, roller type dynamometers or acceleration testers are used to measure the vehicle power. Both of the two kinds of equipment are not very popular for some reasons: the dynamometers are expensive and the acceleration testing rig usually with a little shortcoming, such as in accuracy and the unknown rotation ineria. A partial load acceleration power test method which will improve the performance and keep the lower price was developed. It is suitable and helpful for more vehicle maintenance works.
