چکیده
|
Crack fault of rotor is one of the most prominent problems faced by magnetic bearing rotor system. in order to improve the safety performance of this kind of machinery, it is necessary to research the vibration characteristics of magnetic bearing cracked rotor system. in this paper, the stiffness model of the crack shaft element was established by the strain energy release rate (serr) theory. the mathematical model of pd controller of ambs cracked rotor system is based on the finite element method. the vibration characteristics of pd controller of ambs rotor system were examined in the test rig under crack depth of rotor. the spectrum of vibration characteristics were detected in the ambs cracked rotor system. the results of experiments showed that the 2× and 3× harmonic components can be used for fault diagnosis of crack fault of ambs rotor systems under pd controller of amb.
