摘　　要：风力机叶片是由较为复杂的三维曲面组成。目前,叶片的三维CAD建模普遍采用专用CAD工具,通过模型数据格式转换后再导入CAE模块进行结构分析,使得叶片的几何建模与结构分析过程难以一次完成,不仅影响了建模效率,而且也会因数据转换造成分析模型的精度降低。本文结合当前应用最为广泛的数值分析软件ANSYS的二次开发工具APDL,对风力机叶片的三维几何建模技术进行了定制,实现了叶片CAD/CAE的无缝集成,提高了分析效率。Wind turbine blade is made up of complex three dimensional surfaces. Usually, the geometrical modeling of blade is Firstly built with professional blade CAD software, and then a standard data base can be generated and imported into numerical analysis module. Above modeling process makes the geometrical modeling and structural analysis separation. As a result, not only the modeling efficiency is low, but also some errors caused by data transferring will influence the accuracy of analysis. Based on the most widely used numerical tool ANSYS and its development tool APDL, the blade geometrical modeling module is carefully customized in this paper so that a kind of seamless integration of blade geometrical modeling and analysis is realized, and the efficiency is also raised.
