集装箱船大跨度舱口盖结构强度分析

An analysis on structure strength of large span hatchover in containership

本文给出了集装箱船大跨度舱口盖结构有限元分析的两种不同计算模型，并对这两种模型计算结果进行分析比较，从而找出比较符合实际受力情况的计算模型。在分析计算此模型的基础上进一步分析计算了高应力区域处构件的应力，并提出了对这些构件的加强措施。

The paper first gives two different calculation models using finite element calculation for thestructure strength of the large span hatchcover,the followed by comparison between these two results.As aresult,a calculation model more close to the actual conditions is derived based on this discussion,meanwhile,further analysis and calculation has been conducted to the structure members in the highly stressed areas toderive improvement suggestions to such members.
