| Abstract: | Key NVH technologies of hybrid electric vehicle(HEV) were studied to treat the more complicated noise and vibration problems.The problems came from the new assemblies which include power motor,power battery,etc.,and the new drive modes in HEV.Based on the control theory of vehicle noise and vibration,the structural characteristics of HEV were analyzed and the control methods were discussed from the noise and vibration excitation source,modal distribution,transfer path,evaluation mode and other aspects.At the same time,a new indigenous HEV was presented how to analyze and resolve the NVH problems in its product development process,providing a clear working direction to control noise and vibration performance of hybrid electric vehicle. |
