Multiple Fault Diagnosis Approach for Rotary Machines Based on Matter-Element
An approach was put forward to diagnose the multiple faults of rotary machines according to the characteristic frequency spectrum of vibration. Based on the matter-element of extension theory, a matter-element model was built to describe the fault situation of rotary machines qualitatively. The dependent function and degree of a symptom of the fault were introduced to evaluate the possibility of the fault quantitatively. The diagnosis example was taken to validate the approach. The diagnosed result is consistent with the real result.
