Research of the Fault Diagnosis and Pattern Recognition based on Delayed Correlation-Envelope Technique and Hidden Markov Model

For the degradation characteristic of the gear performance parameter,a method of fault pattern recognition and analysis,which combines the Delayed Correlation-Envelope（DCE）with the Hidden Markov Model（HMM）is proposed.The DCE is used to extract features from vibration signals.The HMM is trained respe...
