| Abstract: | Aim To study the application of wavelet analysis in the vibration state monitoring. Methods Wavelet analysis is illustrated in engineering language, and the typical applications of wavelet analysis in the vibration state monitoring including noise elimination and frequency band separation are briefly discussed. The wavelet energy spectrum and the wavelet wrapnet spectrum method are put forward. Results The method can be used to diagnose fault accurately. Conclusion The application foreground of the wavelet analysis is very wide in the vibration state monitoring. The method is simple and feasible. |
