舰用减摇鳍加强结构的CAD/CAE一体化设计

摘要

针对减摇鳍安装部位复杂的结构形式和载荷引起的结构设计和载荷分析问题,以某舰用不可收放式减摇鳍的加强结构为例,探讨了减摇鳍加强结构三维设计、载荷分析和性能评估方法,将三维设计软件CADDS5优秀的可视化技术和有限元分析软件MSC.Patran/Nastran强大的结构分析能力有效地结合起来,对其进行CAD/CAE一体化设计分析,获得减摇鳍加强结构的力学特性,为结构优化提供依据.%According to the problems of fin stabilizer reinforced structure's complicated design and loads analysis, a naval ship equipped with non-retractable fin stabilizer is taken as an example, three-dimensional design, loads analysis and structure property evaluation method are discussed in this research, which combines effectively the advantages of CADDS5's perfect visualization technology and MSC. Patran/Nastran's powerful structure analysis ability to do CAD/CAE integrated design and analysis. The fin stabilizer reinforced structural mechanics characteristic is obtained, which can supply the value to the structure optimization.
