摘要
基于UG二次开发工具UG/OPEN API和NX OPEN C/C++二次开发功能,结合C/C++编程语言在VS2008平台创建涡扇发动机风扇叶片叶身的中弧面参数化模型和有限元参数化模型,并进行仿真分析。利用壳单元进行分析,对生成的NX Nastran输入输出文件进行数据处理,完成有限元模型的反向迭代过程。该过程能够获得叶片结构的预变形,使得到的叶片模型在外载荷和边界约束条件下,得到与原始模型相互重合的叶片模型。
Using the UG secondary development tools UG/OPEN API and NX OPEN C/C＋＋, and combined with C/C ＋ ＋ programming language in VS2008 platform to create a turbofan engine fan blade body surface in parametric model and the finite element parametric model, simulation analysis was carried on. Using shell element analysis to generate the NX Nastran input and output files for data processing, complete finite element model of reverse iterative process. This process can obtain predeformation of blade structure, make the blade model under external loading and boundary constraint condition, get the blade model coincide with the original model.
