B型LNG独立舱结构的计算分析

摘要

根据DNVGL规范要求,采用有限元方法对B型独立舱结构进行屈服和屈曲强度的校核.根据计算结果,对不满足规范要求的独立舱水平桁肘板趾端区域、靠近支撑装置、止摇装置和止泻装置特别是结构形状变化区域进行结构加强,加强后的独立舱结构可以满足规范要求.%For the structure design of independent type-B LNG tank, as the request of DNVGL rules, structure strength a-nalysis for type-B tank cargo hold was carried out by the finite element method.According to the calculation for yielding and buckling strength analysis, the areas where can' t meet the rule' s requirements were strengthened.Meanwhile, the areas where should be paid more attention were advised for the designers.
