| Abstract: | For fault vibration signal of rotating machinery is complicated dynamic nonstationary,a novel fault diagnosis method based on harmonic wavelet packet and Elman neural network is proposed.Fault signal is decomposed by harmonic wavelet packet and the characteristic vectors of energy are extracted.Then these vectors are input into Elman neural network to distinguish faults.The result of experiment and comparation to BP neural network show that this method has significant advantage in fault diagnosis of rotating machinery. |
| Keywords: | harmonic wavelet packet energy Elman neural network rotating machinery |
