摘　　要：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。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.
