【摘要】 对比传统的雷达罩设计方法,提出了参数化建模方法。在保持外形线不变的前提下.对内形线采用参数化建模技术。生成内形线的三次样条曲线,并建立内形线数据库。然后.借助多学科设计软件 isight 统筹结构与电磁性能分析,对结构分析采用有限元软件,电磁性能分析采用快速多极子算法,使整个设计过程实现了自动化.提高了设计优化效率。更多还原

【Abstract】 Compared to tradtional design method of rodame,a new parametric modeling method of ro- dame is developed in this paper.Based on holding the outline invariable,the inner outline database is esfibilished by using parametric modeling method.Then we give attention to structure analysis and electromagnetism performance at the same time in virtue of muhidisciplinary design software"isight", and the finite element method is used in structure analysis and the MLFMM method is used in electro- magnetism performance analysis.This method realizes the automatization of the design proeodure and improves the optimization efficiency.更多还原
