摘要
小波分析在旋转机械故障诊断领域已有广泛应用。介绍了小波分析的发展及研究现状,阐明了小波分析的基本理论及其特点,详细讨论了小波在旋转机械振动信号去噪中的应用,最后提出一些有待解决的问题及展望。
Wavelet Analysis has been widely used in fault diagnosis of rotating machinery.The development and current research situation of wavelet analysis are introduced.The basic concepts of wavelet theory and characteristics are illustrated.Then the wavelet applications in de-noising of vibration signal of rotating machinery are discussed in detail.At last the problems remaining to be settled are pointed out and the research of applying wavelet is proposed.
