混合动力汽车减振降噪控制技术分析与对策

摘要

文章分析了混合动力汽车发动机、驱动电机、发电机、动力耦合装置、变频器总成、动力电池（HV电池）的噪声及振动特性,并针对混合动力汽车特有的噪声和振动特性,提出了激励源控制和传递路线控制的减振降噪措施。%This paper analyzes the noise and vibration of engine,motor,generator,power split device,converter assembly and battery in Hybrid Electric Vehicle（HEV）.According to the noise and vibration characteristics in HEV,the measurements for noise and vibration control technology such as the excitation source control technology and route control technology are summarized,which may provide a reference for further studying of the HEV noise and vibration.
