Structural Analysis of Container Ship by Global Finite Element Model

以 3 8 0 0 TEU集装箱船为例 ,用二维切片理论进行了波浪长期预报 ,并在此基础上导出等效波组 ,在整船结构有限元模型上计算船体结构在各等效波上的变形和应力分布。文中叙述的整船结构有限元分析方法 。

In this paper, a 3800TEU container ship is taken as an example. 2-D strip theory is used to calculate the long term prediction of wave induced motion and loading, based on which a group of equivalent waves are defined. The bending torsion combined deformation and stress in each part of main structural members of the ship hull under every equivalent wave train are calculated by a 3 D global FE model of the whole ship. The way of FE analysis of the whole ship for the container ship can be used to other types of ships.
