在高速工业平缝机减振阵噪中阻尼技术应用研究

STUDIES ON APPLY DAMPING TECHNOLOGY TO REDUCE VIBRATION AND DROP NOISE OF HIGH SPEED INDUSTRIAL SEWING MACHINE

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。

Abstract In this paper,based on analyzing the noise and vibration characteristics of Neechi--855 Type of High speed industrial sewing Machine. Studies on the relationship between Mddal if machine frame and Vibration or noise in High speed Industral Sewing Machine. Throught the damping treatment in some part of machine frame,its vibration and noise Characteristics are greatly improved.
