基于PCL语言的船体局部结构细网格生成方法

在船体结构详细设计过程中,除了舱段的粗网格有限元分析外,某些局部应力集中处的结构还需要细化分析或进行疲劳强度分析,如肘板趾端、主要构件腹板开孔和舱口角隅等。采用MSC. PATRAN软件中PCL语言进行二次功能开发,可以更为便捷地生成特定结构的细网格,提高船体局部结构细网络的建模效率。

Fine Finite Element Modeling of Local Hull Structures Based on PCL Language

During the hull structure detail design process,some local structures where stress concentration occurs,like bracket toes,openings in main structures or cargo hold corner,may need fine finite element analysis or fatigue strength analysis besides the coarse finite element analysis of the cargo hold.With PCL language of MSC Patran software,secondary development could be implemented to generate particular structure’s fine finite element,which would improve modeling efficiency.
