| 摘 要： | 以大型天线结构为研究对象,提出并实现了一种CAD/CAE集成建模方法.首先在参数化零件的CAD模型上添加分析特征,然后基于带分析特征的参数化零件构建产品的CAD模型,再从CAD模型中提取分析特征并在CAE环境下重构其几何模型,最后应用基于分析特征的网格,自动划分技术快速建立天线整机的有限元网格模型.实例证明该方法可以显著提高复杂产品CAE建模的速度、准确性和一致性.

| Abstract: | A Computer Aided Design(CAD)/Computer Aided Engineering(CAE) integrated modeling method used in Large-Scale Antenna Structure(LSAS) performance analysis was proposed.Firstly,analysis features were attached to parametric CAD model of the part and standard part library was formed.Secondly,the CAD model of LSAS was created by using standard parts.Thirdly,geometrical information of analysis features was extracted from CAD model and reconstructed automatically under CAE environment.Finally,based on the feature-based meshing and combinatorial technique,the CAE model of LSAS was constructed quickly.Through the performance analysis of a 16-meter LSAS,this method was proved to be effective in improving speed,accuracy and consistency of complicated structure CAE modeling. |
