Short-range linear spherical shell短程线型球型网壳

短程线型球形网壳是一种采用正多面体为基础的网格划分方式，具有均匀的网格和优秀的结构性能。整体共有80个面，42个顶点，120条棱。 Short-range linear spherical reticulated shell is a meshing method based on regular polyhedron, which has uniform mesh and excellent structural properties.The whole body has 80 faces, 42 vertices, and 120 edges. 短程线型球形网壳是空间结构中的一种，由美国工程师R. Fuller创立，基于几何学中的短程线原理进行设计。其独特之处在于它的网格划分是基于正多面体，此多面体结构脱胎于正二十面体，在此基础上取两点大圆劣弧上中点并连接各点而成。底座采用镂空设计，网壳各个角度观赏线条排布方式各不相同，独具对称美，呈现出一种有秩序的几何美感。 Geodesic spherical reticulated shell is a type of space structure, created by American engineer R. Fuller, based on the geodesic principle in geometry. It is unique in that its grid division is based on the regular polyhedron, which is derived from the regular icosahedron. On this basis, two midpoints on the great circle and inferior arc are taken and connected. The base adopts hollow design, and the ornamental lines of the mesh shell are arranged in different ways from each Angle, with unique symmetry and beauty, showing an orderly geometric aesthetic fe
