摘　　要：为满足高性能有源相控阵天线的新要求,文中提出了一种具有索桁组合背架与并联驱动装置的创新结构设计方案。建立了该结构方案的有限元模型,通过施加自重、温度、风等外载荷,对天线结构进行了静力学分析。以阵面自重最优为目标,应用序列线性规划法,通过优化索、杆截面尺寸,得到了一组结构方案。与传统方案相比,新方案在保证阵面精度的前提下,型面变形得到了改善,背架总重减少约40%。In order to meet the new requirements of high-performance active phased array antenna, an innovative structure design scheme is proposed, which is composed of a cable-truss combination frame and a parallel drive device. First, the finite element model of this structure scheme is established. The static structure of the antenna is analyzed by applying external loads such as deadweight, temperature and wind. With the objective of optimal deadweight, a set of structure solutions is obtained by sequential linear programming method and optimizing the cable and rod section dimensions. Compared with the traditional scheme, under the premise of ensuring the front surface accuracy, the profile deformation is improved and the total weight of the back frame is reduced by about 40%.
