摘要:作為當代三大主要污染源之一，噪聲污染已成為一個世界性的問題并且引起了世人的關注。隨著工業技術的發展，由物體摩擦產生的噪聲污染也越來越嚴重。對摩擦噪聲進行測量、研究和控制，從環境保護事業出發，是十分需要的；同時通過對摩擦噪聲的信號分析，還可以深入了解摩擦機理，有助于改善摩擦條件和進行工況監測。
關鍵詞:摩擦噪聲；信號分析；工況監測

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
