| Abstract: | Dimensionless parameters are extracted from the time-domain and frequency-domain vibration signals of roller bearing as the evaluation indexes of bearing fault diagnosis.The entropy method is integrated with the grey relational analysis to establish a new grey relational analysis model of bearing fault diagnosis which is based on entropy method.The simulation results of bearing vibration tests show that this method is effective in bearing fault diagnosis and can improve the recognition rate of bearing fault... |
