| Abstract: | A method using 112 dimension spectrum analysis is proposed to derive the features that signify the condition of a bearing.These features quantitatively describe the quadratic phase coupling in vibration signals of rolling element bearings due to localized defects.Experimental results show that the proposed method is effective in bearing defect detection and is sensitive to incipient defects. |

| Keywords: | rolling element bearing fault diagnosis 112 dimension spectrum bispectrum quadratic phase coupling |
