摘要
本文首先详细分析了冰箱及压缩机的振动噪声源。针对顾客比较反感的压缩机管路低频振动引起的噪声,应用动力吸振器原理进行了吸振器设计,并成功应用于压缩机排气管减振降噪,实验结果证明,对冰箱压缩机排气管的振动改善效果明显,低频段噪声明显降低,有效提高了冰箱的声品质。
Firstly,the paper analyzes the vibration& noise source of refrigerator and compressor,finding the annoying factor to customer,especially the low frequency band which is caused by compressor pipe vibration.Apply the dynamic absorber theory to design the absorber which can be applied in refrigerator compressor pipe.After the noise &vibration test,the vibration and noise of discharge pipe are decreased,and the sound quality of refrigerator is improved.
