本文针对K252型丝织机的噪声实际测试数据,对投梭运动噪声的组成及其产生过程作了分析与探讨。 投梭运动噪声不是单一声源所产生、而是多声源的周期性的复合噪声,噪声峰值大多是皮结与有关零件撞击所产生。因此,控制有梭织机的噪声,首先要从投梭机构上着手,尤其要在皮结和皮结相接触的机件上加以研究和改进。 In this paper, according to the actual noise data of K252 silk loom, the composition and the producing process of picking motion noise are analyzed and discussed. The picking motion noise is not generated by a single sound source, but a periodic composite noise of multiple sound sources. Most of the noise peaks are generated by the impact of leather knots and related parts. Therefore, the control of the noise of the shuttle loom, we must first proceed from the pick mechanism, in particular, leather knot and knot in contact with the parts to be studied and improved.
