Abstract: A wavelet neural network is constructed based on wavelet transform principle. A fault diagnosis method based on a wavelet neural network is put forward, the model and algorithms of the network is given. After collecting the vibration signal and computing the spectrum characteristics parameters in frequency domain of the rotating machinery, the samples are learned to train the constructed wavelet neural network for realizing the mapping relationship between the fault and the spectrum characteristic, which can …
