摘　　要：为找出初期大型豪华邮轮船体造型中存在的缺陷,提出基于有限元分析的大型豪华邮轮船体造型研究方法。以某大型豪华邮轮资料实施对标分析构建船体有限元模型,选取四节点减缩积分板单元S4R划分网格,依照相关标准在模型内引入初始几何缺陷。将不同的工况与载荷加载至船体有限元模型上,并设定相应的边界条件,在此基础上分析船体造型的应力与相对变形情况。结果显示:研究对象受整体纵弯矩包络线载荷影响,底部甲板中间区域形成较大面积无法满足应力标准的区域;受整体纵剪力包络线载荷影响,部分强框架局部区域产生的应力变化不符合相关标准;外底板与内底板结构的屈曲应力成分主要为短边受压应力,随甲板高度提升,板格屈曲应力成分从短边受压应力转换成剪切应力。In order to reveal the defects in the hull modeling of large luxury cruise ships in the early stage,a research method for the hull modeling of large luxury cruise ships based on finite element analysis is proposed.Based on the data of a large luxury cruise ship,the finite element model of the ship is constructed by benchmarking analysis.The four-node reduced integral plate element S4R is selected to divide the grid,and the initial geometric defects are introduced into the model according to relevant standards.Different working conditions and loads are loaded on the finite element model of the hull,and corresponding boundary conditions are set.On this basis,the stress and relative deformation of the hull shape are analyzed.The results show that the research object is affected by the load of the overall longitudinal bending moment envelope,and the middle area of the bottom deck forms a large area that cannot meet the stress criteria.Under the influence of the load of the overall longitudinal shear envelope,the stress changes in local areas of some strong frames do not meet the relevant standards.The buckling stress component of the outer bottom plate and the inner bottom plate structure is mainly the short side compression stress.With the rise of the deck height,the buckling stress component of the plate lattice is converted from the short side compression stress to the shear stress.
