  • A fuzzy support vector machine (FSVM) fault diagnosis method was proposed based on improvement of the ordinary diagnosis method used to determine memberships,and an improved diagnosis mathematical model was established.Then,four kinds of typical rotor vibration faults were simulated on a rotor vibration experimental rig,and effective samples of fault were collected.Finally,the validity and feasibility of this method used for rotor vibration fault diagnosis were validated by calculating and analyzing the obtained examples.
