TIME-DELAY VECTOR VARIANCE METHOD AND ITS APPLICATION TO GEAR FAULT DIAGNOSIS

Lü Yong~1 Li Yourong~1 Xu Jinwu~2(1.School of Mechanical Engineering,Wuhan University of Science and Technology,Wuhan 430081;2.School of Mechanical Engineering,Beijing Universtity of Science and Technology,Beijing 100083)  
A time-delay vector variance method which adopts the time series time-delaying and phase space reconstruction for detecting nonlinearity of time series is introduced.The time-delay vector variance method is proposed to detect nonlinearity and classification of machinery fault signal.Numerical experiment results indicate that this method is robust to noise and sensitive to nonlinearity of signal.They show the method can depict signal effectively and visually.When the method is used for nonlinearity detection and classification of gear fault signal,the results are consistent with the facts.
