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
