  • A method for locating rub fault in rotating machinery based on the beamforming of acoustic emission signals was presented.Firstly,the propagation characteristics were obtained by using plate wave theory.On the basis of these results, the feasibility of locating rotating machinery rub fault by the beamforming of acoustic emission signals was confirmed,and the acoustic emission beamforming method was presented.Then,by breaking a mechanical pencil lead on the surface of the stator,the artificial acoustic emission was implemented to verify the presented method.Finally,the present method was used to diagnose the rotor-stator rub fault on the fault experimental device,and the results were analyzed, showing that the acoustic emission beamforming method can identify rub position efficiently.
