Research on Feature Extraction of Shaft Orbit for Rotating Machine

Jiang Zhinong Li Yanni(Diagnosis and Self-Recovery Engineering Research Center,Beijing University of Chemical Technology Beijing,100029,China)  
The shaft orbit is one of the most important features to represent the rotating machine shaft's movement state.Presently,the identification for shaft orbits is limited to the man-machine interaction pattern,and the first step of identification is just completed without any further detail description.In view of this,the automatic identification for shaft orbits is studied,and as a main task,the research on the relationship between shaft orbits and severity of rotor's faults is made.Characteristics quantification is used to subdivide different shapes of shaft orbit denoting the same failure,and the cross point and circle are introduced as the feature parameters.The analysis and simulation achieve good results.
