本文讨论了天线结构的几何优化设计,以结构重量为目标函数,杆件横截面积和节点坐标为设计变量,截面限制、节点坐标限制、节点位移作为约束,其中也反映了精度的要求。结构分析采用刚度法,优化采用具有移动极限的序列线性规划法。最后列举了八米口径天线结构的优化数值结果。
In this paper, the geometry optimization design of the antenna structure is discussed. The structural weight as the objective function, the cross-sectional area of the rod and the node coordinates as the design variables, the cross-section constraints, the node coordinates and the node displacement as the constraints, which also reflect the accuracy requirements. The stiffness analysis is used to analyze the structure, and the sequence linear programming with moving limit is optimized. Finally, the numerical results of the structure of the eight-meter aperture antenna are listed.
