四驱汽车底盘测功机计量检测方法的研究

Investigation of Metrology Method of 4WD Vehicle Chassis Dynamometer

随着不断加严的排放法规的实施,汽车污染排放问题正在成为许多城市环境保护和管理部门关注的焦点。汽车底盘测功机可在室内快速无损地检测汽车各项性能指标,特别是对汽车排放的大气污染物进行检测。本文通过开展四驱汽车底盘测功机的计量检测方法研究,制定了科学合理的计量检测方法,并进行了科学课题实践。实践证明,无论从研究思路、实际操作上,该计量检测方法都具备较强的先进性和可操作性。

With the tightening of emission regulations, the vehicle pollution problem is becoming the focus of many urban environmental protection and management departments. The vehicle chassis dynamometer can detect the performance of the vehicle quickly indoors, especially the air pollutants emitted by the vehicle. In this paper, a scientific and reasonable metrology method is developed by four wheel drive （4WD） vehicle chassis dynamometer calibration. At the same time, a scientific project has been carried out using this metrology method. It has been found that this metrology method has a strong advancement and operability both in theory and the implementation of the program.
