NAPA STEEL在大型集装箱船结构设计中的应用

NAPA STEEL in structural design for large container ships

目前众多三维设计软件在国内船舶生产设计中的应用已相当成熟,而在基本设计和详细设计中的应用尚处于摸索和发展阶段。NAPA STEEL是芬兰NAPA公司开发的船舶设计软件包中的结构设计模块。文章利用NAPA STEEL对2艘万箱级集装箱船进行结构辅助设计,在基本设计和详细设计阶段中参与完成了二维出图、质量统计、船级社软件接口及有限元输出的任务,探索了利用NAPA STEEL软件对大型集装箱船进行参数化建模以完成结构辅助设计的方法,并总结出一些宝贵的经验。

The 3-D design software has been widely used in the ship production design at home, however, its application in the basic design and detail design is still in research and developing stage. NAPA Steel is a ship structural design module in Naval Architecture Software Package（NAPA） that was developed by NAPA Finland. This paper carries out the structural aided design of two 10 000 TEU container ships by NAPA Steel, and fuli lls the 2D drawing, weight estimation, sofeware interface of the classification society and the output of FEM during the basis design and detailed design stage. It explores the capability of NAPA Steel for the parameterization modeling of the large container ships to finish the structural aided design, and summaries some valuable experience.
