摘要
该文从纸机设备频谱分析入手 ,对真空伏辊工作原理及噪声产生机理进行分析 ,确定真空伏辊破真实噪声是抄纸机主噪声源。
Based on the analysis of the frequency spectrum of paper machine,the article analyses the working principle of vacuum couch and mechanism of how the vacuum couch produces noise,and then confirmed that the break vacuum noise of vacuum couch is the main source of noise.
