| Abstract: | A method for simulating two typical rotor faults on a rotor test rig is provided: rotor unbalanced fault and rotor radical friction fault. The features of the vibration signals generated by the faults and the mechanism of producing such features are analyzed. Processing results of the signal under normal and fault condition are given both in the time domain and in the frequency domain .Both test and analysis get identical diagnosis features of the two faults, which would enrich the database of fault diagnosis of rotating machinery. |
