摘要
作为当代三大主要污染源之一,噪声污染已成为一个世界性的问题并且引起了世人的关注。随着工业技术的发展,由物体摩擦产生的噪声污染也越来越严重。对摩擦噪声进行测量、研究和控制,从环境保护事业出发,是十分需要的;同时通过对摩擦噪声的信号分析,还可以深入了解摩擦机理,有助于改善摩擦条件和进行工况监测。
As the one of the three primary source of ponution,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.
