Abstract

The invention relates to a noise recognition method for a high-end textile manufacturing machine based on transfer path analysis, and the method comprises the following steps: measuring a frequency-response function of transfer paths of a plurality of excitation sources; measuring the sound pressure and a working load under the measurement work condition; and calculating a noise contribution amount through the acceleration of the excitation sources, the sound pressure under the work condition and the working load. The method can achieve the recognition of the amplitude of main noise of the high-end textile manufacturing machine under the work condition and the noise contribution amount of a main sound generating mechanism.

Description

technical field [0001] The invention relates to the technical field of mechanical system vibration and noise identification, in particular to a high-end textile machinery noise identification method based on transmission path analysis. Background technique [0002] With the continuous improvement of the vibration and noise performance of high-end textile equipment, the noise value of the textile machinery workshop can no longer reflect the health impact of the vibration and noise of the textile machinery under the operating conditions of the workers and the damage of the vibration to the machinery itself. Therefore, studying the transmission path analysis and identifying noise plays a vital role in improving the quality of textile machinery. [0003] Most of the noise identification methods applied to textile machinery in engineering have problems such as low economic benefit, complicated test equipment and long time period. The transfer path analysis method can evaluate th...
