摘　　要：热泵系统的振动噪声性能在新能源汽车整车NVH舒适性评估中起到至关重要的作用。本文根据热泵系统的结构和工作特点,结合汽车振动噪声控制原理,从振动噪声激励源、结构模态分布、传递路径、评价工况等多个维度开展了热泵系统振动噪声控制方法研究。通过分析某国产混合动力轿车在热泵产品开发中的NVH问题,提出相应的解决方案。结果表明:热泵NVH控制是一个系统工程,压缩机、空调管路、HVAC箱体、声学包以及压缩机控制策略是NVH的重要影响因素,为新能源汽车热泵系统的振动噪声性能控制提供了清晰的技术参考。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,trans⁃fer 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 sys⁃tem 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 perfor⁃mance control of new energy vehicle heat pump systems.
