8万总吨邮轮全船及局部结构强度分析

Global and Local Structural Strength Analysis of a 80 000 GT Cruise Ship

邮轮由于自身结构的特殊性,对其进行结构强度分析十分关键。根据CCS邮轮规范对8万总吨邮轮目标船进行基于包络值分析方法的全船有限元结构强度分析,利用子模型分析方法对典型的特殊空间区域进行局部结构强度分析,同时对典型的阳台开孔结构进行细模强度评估及优化,通过分析、评估及加强保证邮轮整体及局部结构强度安全可靠,为中大型邮轮的结构强度分析及评估提供有益参考。

Due to the special structure characteristic of cruise ship,structural strength analysis is very important.Global finite element analysis(FEA) of whole ship structure based on envelope rule loads and local FEA of the typical special area with submodel analysis method were performed for the target 80 000 GT cruise ship according to the CCS rules.At the meantime,the structure assessment and optimization with fine mesh analysis was carried out for typical balcony opening.The safety and reliability of the global and local structures could be ensured with abovementioned analysis,assessment and strengthening.The helpful reference was provided for the structural strength analysis and evaluation of medium and large sized cruise ship.
