Outline
The vibration and noise performance of the heat pump system plays an important role in the NVH evaluation of new energy vehicles. Based on the structure and working characteristics of the heat pump system and the principles of vehicle vibration and noise control，a research on the NVH control methods of the heat pump system is carried out in this paper from the vibration and noise excitation source，structural mode distribution，transfer path，evaluation conditions and other dimensions. Through the analysis and solution of NVH problems in the product development of a domestic hybrid electric car，the results indicate that the NVH control of heat pump system is a system engineering，and the compressor，air conditioning pipeline，HVAC shell，acoustic package and compressor control strategy are key factors of NVH，which provides a clear technical reference for the NVH performance control of new energy vehicle heat pump systems.
