集装箱船船体强度校核方法

集装箱船由于其大开口结构，在进行船体强度校核时必须考虑扭转产生的翘曲应力。本文以ＫＯＴＡ ＩＮＤＡＨ／ＩＮＴＡＨ集装箱船为例，通过建立三维有限元模型，应用规范和有限元相结合的方法对船体弯曲应力和翘曲应力进行了计算，并以规划标准进行了判别。

Procedure for Checking Hull Strength of Containership

The warping stress induced by torsion should be taken into account in the process of checking the hullstrength due to the large opening structure of the containership. In this paper, a containership, KOTA INDAN/INTAN, is taken as an example, the bending and warping stress of the hull are calculated by rules with finite ele-ment method on the basis of setting up a three-dimentional finite element model. The judgement is made in compli-ance with the rules' standards as well.
