| 摘 要： | 分别运用基于非线性有限元法的通用软件MSC/Mare以及基于逐步破坏法的自编程序SUS对1艘液化天然气(LNG)船的船体极限强度进行分析.探讨了LNG船船体极限强度计算的思路和方法,并将两种方法对该船的船体极限强度计算结果进行比较分析.结果表明,利用MSC/Marc程序对LNG船进行船体极限强度分析的结果与简化方法(SUS)的结果相近,并得出了一些有价值的结论.

| Abstract: | This paper presents two methods of the ultimate strength analysis for an LNG ship,using common software MSC/Marc based on non-linear finite element method and SUS program written by the authors based on progressive method.The ideas and methods of hull ultimate strength for the LNG ship are discussed,and the calculated results of the two methods are compared with each other.The results show that the calculated values of hull ultimate strength with two different methods are close,and some worthy conclusions a... |
