Abstract
A kind of CAD/CAE integrated modeling method based on feature is proposed. Firstly, analysis features are attached to CAD model of part and standard part library is formed. Secondly, the CAD model is created using standard parts. Thirdly, geometry information of analysis features is extracted from CAD model and is reconstructed automatically under CAE environment. Finally, based on feature-based meshing and combination technique, CAE model is built quickly. A prototype software for large-scale antenna structure (LSAS) CAD/CAE integrated modeling has been developed and used in performance analysis of a 16-meter-diameter LSAS. The method has been proved to be useful for improving speed, accuracy and consistency of complicated structure CAE modeling notably.
