滚动轴承的MSE和PNN故障诊断方法
Fault Diagnosis of Rolling Bearings Using MSE and PNN
摘要
Abstract
Considering different levels of complexity of vibration signals of rolling bearings in different operating conditions, a novel fault diagnosis method has been proposed based on the multiscale entropy (MSE) and probabilistic neural networks (PNN). Fault feature vector is firstly extracted from the vibration signals using MSE and then provided to PNN neural network as the input. The PNN network will identify the bearing fault type and severity level simultaneously. The experimental data are collected from an induction motor bearing involving various fault types and severity levels. The results demonstrate that the proposed method has a higher accuracy in rolling bearing fault diagnosis than the method of the combination of wavelet packet decomposition with PNN.关键词
