基于 UG 二次开发工具 UG/OPEN API 和 NX OPEN C ++以及 C 编程语言的二次开发功能,结合 VS 2008平台对涡扇发动机风扇叶片结构进行叶片模型、有限元模型和仿真模型的参数化创建,同时研究叶身中弧面厚度信息的提取问题.将提取的厚度信息加载到壳单元网格上,使其具有实体特性,利用该单元对叶片进行网格划分,并进行求解分析,对比实体单元网格分析结果.仿真结果表明,在相同的计算模型下,实体壳单元能够减少计算时占用内存的24.65%和计算时间的45.97%,提高计算效率,减少计算周期.

By the UG secondary development tools UG/OPEN API and NX OPEN C ++,and the integrated use of the C programming language,fan blade model,finite element model,simulation were created model parameterization on VS2008 platform.The measure of acguiring the information about the fan blade thick-ness information was also studied.The shell thickness of unit was loaded to mak it a solid shell element with physical properties.Solid shell element was used to mesh the fan blade in simulation analysis.Under the same calculation model,compared solid element and solid shell element analysis results,the solid shell element could effectively reduce computing scale(24.65%)and calculation time(45.97%)so it improved the computing efficiency,and reduced the computing time.
