Co-relation between Shafting Vibration Performances and Shafting Mechanics Characters in Large Ships

Ship shafting mechanical characteristics reflected the ship shaft system static and dynamic mechanics characteristics, through the ship shafting alignment through theoretical analysis and calculation of ship shafting vibration characteristic includes shafting torsional vibration, transversal and longitudinal vibration characteristics, etc. In this paper, through theoretical and experimental analysis method of combining the research of shafting mechanical characteristics and the influence of the relationship between shafting vibration, theoretical analysis method is applied to analyze the changes on static mechanics characteristics of ship shaft, the test method for research of ship shafting torsional vibration and longitudinal vibration characteristics, and the bearing load and the shafting vibration characteristic frequency and the amplitude as a characteristic, analytical mechanics characteristics change on the influence of shafting vibration characteristics. Finally, summarized some preliminary conclusion, influence law for ship shafting in researchers to provide the reference to the theory, method and train of thought.
