1515型自动棉织机降噪研究

Study on Reduced Noise for Type 1515 Automatic Fly-Shuttle Loom

从撞击噪声形成机理出发,分析了1515型自动棉织机噪声的声学特性和主声源.以结构加速度噪声、自鸣噪声和声辐射系数等声学理论为依据,确定织机的噪声治理方案,对织机投梭系统的主要零器件,进行于阻尼降噪处理,使织机噪声水平下降10dB(A)以上.

Impact noise theory is used to study the noise properly from the type 1515 loom and to identify the noise source.Some damping treatments are made to reduce the acceleration noise,ringing noise and noise radiation effi- ciency of the loom on the basis of analysis and experiments,and the impact noise level of the loom is reduced by about 10 dB(A).
