30000吨多用途船船体舱段强度的有限元计算分析(英文)

Finite Element Calculation of Three Dimensional Hold Section Strength of 30000 DWT Multipurpose Ship

本文对30000吨多用途船船体舱段强度进行了有限元直接计算分析。按照GL规范直接计算的要求 ,舱段载荷除了考虑水压力载荷、货物载荷和自重等舱段局部载荷外 ,还要考虑总强度的影响作用。经过满载工况、压载工况和起重机作业工况的计算 。

In this paper,we calculate and analyze the strength of the hold frame of a 30000 DWT multipurpose ship by 3D F.E.M.According to direct calculation of GL Rules,the influence of longitudinal bending moments must be taken into account together with the local loads of hull sections such as hydrodynamic pressure,cargo load and gravity load.The hull structure stresses and distortions are calculated under ballast,full and derrick operating load conditions.The calculations indicate that the ship strength can be ensured sufficiently according to direct calculation of GL Rules.
