大型船舶结构有限元静动力分析方法及软件系统

The Static and Dynamic Analysis Methods and Software for Large Ship Structure

讨论了船舶结构有限元模型化问题，提出了几个船舶结构分析专用单元。这些单元能准确地反映船舶结构的特点，既能保证精度又有很高的效率。同时，还介绍了一个由作者开发的结构静力、动力有限元分析软件系统SAFE。它具有通用单元库和船舶结构专用单元库，可以进行有限元与边界元的耦合分析。SAFE有高效率的内外存文件管理系统和前后处理软件，可在微机上进行全船分析，是船舶结构设计阶段的一个理想的分析工具。

The finite element modeling of ship structure is discussed. Some special purpose finite elements which are accurate and efficient for ship structural analysis are proposed. A finite element software system──SAFE for static and dynamic structural analysis has been developed. This software has both special and general purpose finite elements for ship structures and can perform the analysis by coupling finite element and boundary elements. Equipped with efficient file-managing module and pre-/post-processor,SAFE is capable of analyzing an entire ship on a PC.
