| 摘 要： | 对豪华邮轮进行全船结构强度分析是其结构设计的必要条件。文章基于LR规范,介绍豪华邮轮有限元分析流程,包括边界条件、设计载荷、计算工况和强度准则等,以某艘14万总吨级的豪华邮轮为实例,采用有限元手段对其全船结构强度进行计算,并分析应力分布特点和主要纵向连续结构的有效度,结果表明:该邮轮结构的总纵正应力和剪应力主要分别由甲板结构及连续纵舱壁结构参与传递。该结论可为豪华邮轮结构设计提供一些参考。

| Abstract: | The overall structural strength analysis of the luxury cruises is necessary for the structural design of the luxury cruises.The processes of the finite element analysis of the luxury cruises are introduced based on the specifications of the Lloyd’s Register(LR),including the boundary conditions,design loads,working conditions and strength criteria.The overall structural strength of the 140000 gross tonnage luxury cruise is calculated by using the finite element method.The characteristics of the stress distribution and the availability of the major longitudinal continuous structures are also analyzed.The results show that the overall longitudinal normal stress and the shear stress of the cruise are mainly transmitted by the deck structure and the continuous longitudinal bulkhead,respectively.The conclusions can provide reference for the structure design of the luxury cruises. |
