包络－小波分析法用于滚动轴承故障诊断的研究

STUDY ON ENVELOPE WAVELET ANALYSIS AND ITS APPLICATION TO ROLLING BEARING DIAGNOSIS

根据现有的小波理论和滚动轴承的振动特征，提出了傅里叶分析与小波分析相结合的包络－小波分析法，研究了其基本原理和在滚动轴承故障诊断中的实际应用。

According to wavelet theory and the vibration characteristics of rolling bearing, the envelope wavelet analysis of combining Fourier analysis with wavelet analysis was put forward. Its basic principle and practical application to rolling bearing diagnosis have been studied, and a diagnostic example was given.
