从共振角度对压缩机低频撞击噪声的分析

Analysis of low frequency impact noise of compressor from the resonance angle

目前变频压缩机匹配空调时存在低频撞击噪声问题,通过分析发现其噪声来源主要由滑片与滚子脱离撞击造成。本文从振动角度进行分析,建立振动模型,进行理论分析计算,最后给出相应的解决方案。

At present, it is found that the low frequency noise in the matching process of the variable frequency compressor, the noise source is mainly caused by the sliding vane and roller. In this paper, from the perspective of vibration analysis, the establishment of vibration model, the theoretical analysis and calculation, and finally gives the corresponding solutions.
