小波技术在机械监测诊断领域的应用现状与进展

Development and Status Quo of Applications on Wavelet Technology for Mechanical Surveillance and Diagnosis

对近两年我国及日本在机械监测诊断领域内小波技术的研究与应用进行了回顾 ,简述了小波技术的理论研究及其在旋转机械、往复机械、齿轮、轴承、建筑结构、疲劳损伤等方面的应用中所取得的可喜进展和特点 .指出应根据小波函数的性质有针对性地应用 。

Researches and applications on wavelet technology in China and Japan are reviewed in the field of mechanical monitoring and diagnosis in recent two years. Encouraging progresses and characters in theoretical research and practical application for rotating machinery, reciprocating machinery, gear and bearing, damage detection etc.are sketched.It is important to adopt wavelet functions purposefully based on their properties. Only in this way,can better effects be obtained.
