摘要:作為當(dāng)代三大主要污染源之一，噪聲污染已成為一個(gè)世界性的問(wèn)題并且引起了世人的關(guān)注。隨著工業(yè)技術(shù)的發(fā)展，由物體摩擦產(chǎn)生的噪聲污染也越來(lái)越嚴(yán)重。對(duì)摩擦噪聲進(jìn)行測(cè)量、研究和控制，從環(huán)境保護(hù)事業(yè)出發(fā)，是十分需要的；同時(shí)通過(guò)對(duì)摩擦噪聲的信號(hào)分析，還可以深入了解摩擦機(jī)理，有助于改善摩擦條件和進(jìn)行工況監(jiān)測(cè)。
關(guān)鍵詞:摩擦噪聲；信號(hào)分析；工況監(jiān)測(cè)

Abstract: As the one of the three primary source of pollution, noise pollution has become worldwide problem and aroused earthling attention. With the development of industrial technology, noise pollution caused by body friction has been increasingly serious. For the sake of environmental protection, it is very necessary to measure, research and control the frictional noise. At the same time, with the analysis of this noise, we have a better understanding of mechanism for friction.It is also beneficial to the improvement on rubbing condition and the work condition monitoring.
Key words: Frictional noise; Signal processing; Work condition monitoring
