摘要
针对发动机进气道螺旋曲面特征,提出一种进气道参数化三维造型方法,综合运用UG二次开发工具,构建点,建立进气道曲线方程,通过曲线构建曲面并编辑,开发出进气道三维参数化自动建模系统。该系统能够根据给定参数自动快速建立参数化模型,达到CAD/CAE的集成,为后续分析工作提供支持。
With consideration of the spiral surface of the engine, a parametric three dimensional modelling of inlet is proposed in this paper. Various tools of secondary UG development are employed comprehensive- ly to construct points and to establish inlet surface equations. The automatic modelling system is developed by constructing and editing the surface. The modelling system integrating CAD/CAE can build parametric models automatically and quickly based on given parameters, which provides effective support for analysis afterwards.
