An Integration Method of Hybrid F. E. Models of Ship-Hull in Calculating the After-Body Vibration of Ships

This paper researches an integration method of hybrid F. E. models of ship-hull for calculating the after-body vibration of ships. By analyzing the characteristics and integrationmethods of the existing finite element models, a special beam element device connecting F.E. model and beam model to simulate the ship structures is proposed, and the general principles are given to determine the relevant parameters of the special beam elements. The specialbeam element simulating method proposed herein is simple, clear and easy to use. Thismethod can be widely used in hybrid F. E. models of ship-hulls for calculating the ship's vibrations and local vibrations.
