Abstract: In order to verify the accuracy and reliability of the signal collecting of torsional vibration and fault monitoring, a set of data collecting and processing systems of torsional vibration of ship propulsion shafting was designed. At the same time, using combination of gear and photoelectric switch for the sensors, the signal conditioning box of National Instruments(NI) Corporation and data collecting card as the main devices, the signal collecting of torsional vibration was completed. In addition, a software of the fault monitoring and analysis was developed with Visual C++. The signal real time collecting of torsional vibration and processing were realized. Experimental results indicate that aim of the design is achieved, which satisfies the needs of teaching and scientific research.
Key words: ship propulsion shafting; torsional vibration; data collecting; fault monitoring
