摘　　要：采用实船舱段模型分析船体结构强度过程较为复杂且耗时较长,建立简化模型是实现邮轮舷侧结构强度快速评估的有效手段,可为其初步设计提供重要支撑.文中基于劳氏船级社规范中的多甲板大型客船上层建筑舷侧开口结构强度校核评估计算方法,建立评估大型邮轮舷侧结构弯剪强度的简化计算模型,研究含开口舷侧结构在波浪弯矩作用下的承载特性和失效模式.结果表明:在静强度分析中,舷侧简化模型与全船半宽模型在波浪载荷作用下的应力分布和破坏位置基本一致;在极限强度分析中,简化模型可快速评估含开口舷侧结构的极限载荷及失效模式,文中所提出的舷侧结构简化模型为邮轮及客船结构设计提供了简便建模及分析方法.The process of the analysis of the structural strength of the hull using the full ship model is more complex and time-consuming,and the establishment of a simplified model is an effective method to achieve a rapid assessment of the strength of the ship′s side structure,which can provide an important support for its preliminary design.Based on the evaluation method of the strength assessment of the strength of the side opening structure of the multi-deck large passenger ship in the Lloyd′s Register rules,a simplified model for evaluating the bending and shear strength of the side structure of the large cruise ship is established,and the load carrying characteristics and failure mode of the opening in side structure under the action of the wave bending moment are studied.In the static strength analysis,the ship side simplified model shows the similar stress distribution and failure position of the full-ship half-width model under the action of wave load.In the ultimate strength analysis,the simplified model provides a rapid assessment of limit loads and failure modes of side structures with openings.The simplified model of the side structure proposed in this paper provides a simple modeling and analysis method for the structural design of cruise ships and passenger ships.
