| Abstract: | The purpose of this paper is to discuss the full use of the shape and dynamic feature of orbit of shaft centerline of marine turbine,and to make good use of it for fault diagnosis. A kind of automatic recognition system was designed. The structure,function and means of recognition of the system were introduced and the BP neural network was in use for the system . The system can automatically recognize the orbit of shaft centerline of marine turbine rotor for a certainty of identification probability. |
