摘　　要：为优化充气展开天线支撑结构,采用四边形四节点薄壳单元建立充气支撑管和支撑圆环的有限元分析模型.利用ANSYS软件,首先计算内压作用下结构的应力和固有频率,然后依次采用0阶和1阶优化算法对结构尺寸进行参数优化,有效地降低结构整体质量.该尺寸优化可以大大缩短设计周期,提高设计水平.To optimize the support structure of inflatable space antenna, the finite element analysis model for inflatable tube and torus is established by four node quadrangular shell elements. By using ANSYS, the static and natural frequency of the structure subjected to inner pressure are obtained, and two optimization methods with zero order and first order are used to optimize the structure size parameters. The total mass of the structure is reduced efficiently. The optimization can shorten its design cycle greatly and improve its design level.
