【摘要】：基于从平面单元到凸多面体空间单元拓扑映射的约束条件,以特征角点坐标作为变量,建立双边凸多面体约束方程组,求特征角点径长的变异系数的极小值,实现多边形构型凸多面体的球形优化,从而建立了一种可实现多边形构型双边球形凸多面体系列化构建的解析计算方法。将旋转对称性双边球形凸多面体对应的大矢跨比球冠应用于天线罩,具有以下显著优势:球形网壳结构具有良好的力学性能;由于多边形网格具有平面性,因此透波窗口便于做成薄膜单层形式,这是有利于天线罩取得良好电磁性能的因素。
[Abstract]:Based on the constraint conditions of topological mapping from plane element to convex polyhedral space element, taking the coordinate of characteristic corner as a variable, the bilateral convex polyhedral constraint equations are established, and the minimum value of the coefficient of variation of the diameter length of characteristic corner is obtained. The spherical optimization of polyhedral convex polyhedral is realized, and an analytical calculation method is established to realize the serialized construction of bilateral spherical convex polyhedral. The large rise-span ratio spherical crown corresponding to the rotating symmetry bilateral spherical convex polyhedral is applied to the radome, which has the following remarkable advantages: the spherical reticulated shell structure has good mechanical properties; Because the polygonal grid is planar, the transmission window is easy to be made into a thin film monolayer, which is a factor conducive to the good electromagnetic properties of the radome.
