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.
Key words: wavelet transform fault diagnosis pattern recognition
