ZhuShunkuan,Xia Yinyuan (CheryAutomobileCompanyLimited,Wuhu241007)

【Abstract]The noise source and the noise transmissionof the compressorNVH problem of the electric vehicle heat pump systemarestudied,andtheimprovementisadebyptimizingtheinteralstructureofteelectricompresor,nceasigthe acousticpackageand optimizing theairconditioningpipeline.TheNVH testresultsshow that theinternal structure optimizationcanreducethevibrationexcitationnoiseoftheelectriccompressorwhiletheadditionofacousticpackage andair conditioning pipelineoptimizationcan reduce thecompressrnoise transmission.These enhancementscontribute toa reduction in the noise levelofthe heat pump system during operation and theNVH performance of the vehicle.

1前言

傳統(tǒng)燃油汽車空調(diào)系統(tǒng)的噪聲源一般為固定于發(fā)動(dòng)機(jī)的空調(diào)壓縮機(jī),發(fā)動(dòng)機(jī)懸置的減振作用減少了噪聲問題的發(fā)生。(剩余5340字)
