摘要
采用频谱分析技术，研究了ＱＤ５５Ａ冰箱压缩机主要噪声来源，提出了以减小压缩机气流脉动性噪声为主的降噪措施。经批量生产测试验证，噪声下降４ｄＢ。
This paper propose an approach to reduce the regular pulse noise from ofQD55A air flow refrigerator compressor.The Rource is analysed by spectral a nalyeis techiques.Thenoise level is droped 4dB via massive preduction testing verification,and a desirable result on noise reduction has been obtained.
