| Abstract: | By using finite element technique(FET), the free vibration frequency of ship hull and superstructure,as well as the local free vibratiton frequency of decks are predicted. The single-deck model,stern superstructure model,overall ship model and the simplified overall ship model used for vibration calculation and their applications are introduced respectively.The coupling effect between hull and superstructure are investigated and the effectiveness of various modelling method are evaluated on the basis of calculated examples. |
