Vibration Analysis For The Superstructure Of Large Scale Container Ships

This paper analyzed the superstructure's vibration of large scale container ships and includes:1) Forecasting for superstructure's global vibration of container ships;2) Analytical method calculation for superstructure's local vibration of container ships;3)FEM method calculation for . superstructure's global vibration of 1714TEU container ship;4) Vibration test on board the 1714TEU container ship.Firstly,this paper described two methods for forecasting superstructure's global vibration of container ships and,performed the forecasting and comparing the superstructure's global vibration for 1714TEU and 5618TEU container ships respectively by these two methods.Secondly,this paper described two analytical methods for calculating superstructure's local vibration of container ships and,calculated and compared the natural frequencies of local structure for 5618TEU container ship's superstructure by these two methods.Thirdly,the superstructure's global vibration of 1714TEU container ship was calculated by FEM methods in this paper.Finally,vibration test on board the 1714TEU container ship was described in this paper.
