摘　　要：文章介绍了基于底盘测功机的针对市场上某款牵引汽车加速性能不足问题的排查过程。重点阐述了如何利用底盘测功机同步采集时间和车辆轮边驱动力,反推车辆的输出扭矩,并通过加速时间、扭矩对比的曲线来完成排查分析。This paper introduces the troubleshooting process based on chassis dynamometer for the problem of insufficient acceleration performance of a certain tractor on the market. This paper focuses on how to use the chassis dynamometer to synchronously collect time and wheel side driving force to push back the output torque of the vehicle, and complete the investigation and analysis through the curve of acceleration time and torque comparison.
