Bearing Fault Diagnosis Based on Status Prediction and Fractal Dimension Criterion
Hong Li · Machine Tool & Hydraulics · 2006
The vibration signal implies a lot of status information of bear system.The status prediction could be got based on the measurement signal,and the diagnosis could be done based on the prediction.Using data processing combination based on phase space reconstruction method,the status prediction was made,and the status was analysed using fractal theory and generalize fractal dimension was defined to classify the fault and type.The method is better than traditional spectrum method.
