基于 A NSYS 的 9 m 天线静动态特性分析

摘要

基于大型有限元分析软件ANSYS ,构建某9 m口径圆抛物面天线的实体模型 ,在自身重力和稳态风荷作用下 ,对天线进行了静态特性分析 ,验证了天线的设计强度 ;通过模态分析计算出天线前10阶固有频率及固有振型 ,分析了天线的动态特性 ,找出薄弱环节 ,以便更好地展开后续的研究.%Based on the finite element analysis software ANSYS ,a digitized model was established for a 9 m diameter circular parabo-loid antenna .Under the action of dead load and steady-state wind load ,the static characteristic analysis was made to verify the de-signed rigidity and intensity of antenna;the modal analysis was made to get the natural frequencies and vibration modes of first 10 or-ders ,the dynamic characteristics of the antenna was analyzed ,and the weakness was got ,to get the better follow-up study .
