本文在Ｎｅｅｃｈｉ－８５５型高速工业平缝机噪声和振动特性分析的基础上，初步探讨了机壳模态与高速工业平缝机振动和噪声源，通过对机壳局部阻尼处理，其振动和噪声特性有了很大改善。
Based on the analysis of noise and vibration characteristics of the high-speed industrial sewing machine Neechi-855, the vibration and noise sources of the machine shell mode and high speed industrial sewing machine are discussed preliminarily. Through the damping of the cabinet, the vibration and noise Features have been greatly improved.
