| 摘 要： | 从理论上分析了板单元一实体单元相结合的单元刚度矩阵转化问题。并在此基础上，基于耦合和约束方程处理方法，建立了板单元和实体单元相结合的箱体式雷达天线结构有限元模型。通过分析结果与变形测试试验结果和其它有限元建模方法之间的对比，证明了所建立的有限元模型的合理性。

| Abstract: | This paper analyzed from theory on the rigidity matrix transformation problems of the combination unit of plate unit and entity unit. And on this basis, the finite element model of case typed radar antenna structure integrated with plate unit and entity unit was established on the basis of handling method of coupling and constraint equations. Through the comparison among the result of analysis and the result of deformation testing experiment and other finite element modeling method, the rationality of the being established finite element model has been testified. |
