Mechanical Vibration Analysis Using ANC and Morlet Wavelet
A method of vibration analysis for mechanical fault detection based on adaptive noise canceling(ANC) and envelope analysis was presented. The adaptive filtering was used for noise canceling and feature extraction from vibration signal measured for the detection. The envelope analysis based on analytic wavelet was also used for the fault detection. Experiment shows that the method proposed in this paper is very effective for reducing noise, and for vibration analysis to discriminating the fault types with a high accuracy.
