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。
Based on the constraints of topological mapping from planar elements to convex polyhedrons, the constraint equations of bilateral convex polyhedron are established by taking the coordinates of the characteristic corner points as variables to find the minimum value of the coefficient of variation of the feature points’ The spherical optimization of the polyhedron is thus established to establish an analytical method that can be used to construct a series of bilateral spherical polyhedra with polygon configuration. The large symmetry bilateral spherical convex polyhedron corresponding to the large-span ball than the radome applied to the radome, has the following significant advantages: spherical reticular shell structure has good mechanical properties; polygonal grid with planarity, so easy to create a transparent window Single-layer film form, which is conducive to the radome to obtain good electromagnetic properties of the factors.
