摘　　要：以某超大型液化气船84 000m^3 VLGC的3号液舱为例,运用MSC.Nastran软件,采用直接加载和惯性释放两种方法分析液舱整体吊装时结构在自重作用下的响应。对两种有限元分析方法的计算结果进行对比研究,其相关结论对大型总段吊装分析具有较强的指导意义。Taken No.3 liquid tank of 84 000 m 3 Volumetric Liquefied Gas Container(VLGC)for example,the structure response of the liquid tank under its own weight in integral hoisting is analyzed with direct loading method and inertial releasing method by the software of MSC.Nastran.The calculation results of the two finite element analysis methods mentioned above are compared.The conclusion is of significance for guiding the work of large block hoisting.
