Feature Extraction From the Orbit of the Center of a Rotor Based on Wavelet Transform

Duan Jian Zhang Xiaodong (College of Mechanical and Engineering,Xian Jiaotong University Xian, 710049)  
There are lots of messages in the orbit of the center of a rotor that show some operating states of the rotatory machine. However, for the serious interferences, it is so confused that useful messages can not be obtained from it. In this paper, the wavelet thansform is used to eliminate the interferences. The features of the fault are extracted easily, and satisfactory results are obtained.
