摘　　要：针对桁架式内腔空心风扇叶片,运用UG二次开发工具UG/Open API,NX Open C++及C++编程语言混合开发方法,在UG环境中,建立空心叶片参数化三维模型和参数化有限元模型,在叶片有限元网格形式不变的前提下,快速生成叶片有限元模型,有效解决优化过程中网格自动更新问题。在此基础上,自动施加边界条件和载荷,从而实现集造型、分网、分析为一体的自动化设计。实例表明,宽弦空心风扇叶片参数化设计平台不仅可以快速完成空心叶片参数化设计及强度分析,也可为后续开展叶片结构优化奠定基础。Aiming at the hollow fan blade＇s internal structure of girder type, the hollow fan blade＇s parametric three- dimensional model and parametric finite element model are established in UG through combining UG secondary development tools, such as, UG/Open API,NX Open C＋＋ and C＋＋ programming language. And without changing the finite element grid, it allows the rapid generation of the fan blade＇s model and efficient solutions to the grid＇s automatic upgrading problems during the process of optimizing. Moreover, boundary condition and load were forced automatically, so as to achieve the collection of modeling, meshing, and analysis for the integration of the automation design. Examples show that, the parametric design platform of hollow fan blade can not only done quickly structure design and stress analysis of hoUow blade, but also lay a solid foundation for the follow-up blade structural optimization.
