摘　　要：本文以FFC— 2 3A型爪式粉碎机为样机 ,利用现代声学测试分析手段对其工作时定齿盘内、外圈齿与相应动齿相掠过所产生的旋转噪声进行了试验分离研究 ,从而得出了爪式粉碎机旋转噪声的主要成分源自工作中外圈定齿与其相互作用的动齿所产生的噪声。Taking the FFC-23Adisk mill as a specimen model, the rotation noisegenerated from the interaction between fixed claws distributed on the outer and innercircle of the fixed claw plate and the corresponding moving claws has been separated in an experimental study by the modern analytic method of acoustic. Thereby, aconclusion that the principal component of rotation noise in disk mill comes from the interaction between the fixed claws on the outer circle and the corresponding moving claws has been reached.
