大型集装箱船整船有限元分析计算技术研究

Research on numerical technique of whole large container ship by FEM

本文在研究大型集装箱船整船分析的基础上,总结研究和发展了二种集装箱船整船有限元分析时调整节点力和惯性平衡的处理方法。对于正确地进行大型集装箱船整船结构强度直接计算具有指导作用和实用价值。同时本文提出了对集装箱船整船结构强度分析的分工况计算和应力合成技术,可应用于集装箱船的整船结构有限元计算分析。

Two methods by adjusting nodal forces and inertia equilibrium for FEM analysis are developed, which can be applied directly to correctly analyze the global strength of whole large container ship. The technique of sub-case evaluation and stress composition are involved and can be used in the FEM analysis of whole large container ship.
