摘    要：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，并给出了诊断实例。

Abstract: According to wavelet theory and the vibration characteristics of rolling bearing, the envelope-wavele 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.
