The Feature Extraction and Diagnosis of Rolling Bearing Based on CEEMD and LDWPSO-PNN
The vibration signals of rolling bearing are often highly nonstationary and nonlinear, and consequently it is not accurate to extract and identify the characteristics of these signals by the traditional methods. In order to improve the performance on the feature extraction from bearing signals and t...
