Based on the theory of average arc,the geometry characteristics of geodesic spherical reticulated shells is studied,and a method of modeling geodesic spherical reticulated shells is put forward by combining orthogonal coordinate with spherical coordinate.
根据等弧均分法,分析了短程线型球面网壳的几何特性,将直角坐标与球面坐标相结合,利用ANSYS的二次开发技术建立了一种短程线型球面网壳结构的建模方法,编制了相应的宏程序,实现了其参数化建模。
In particular,for v=m=1,the usual exterior transformations,between the spherical coordinate and Cartesian coordinate,as well as the cylindrical coo.
首先介绍了分数微积分和分数微分形式· 讨论了在原点处对曲线坐标的分数外微分变换,并且获得了从三维卡氏坐标到球面坐标和柱面坐标的两个分数微分变换· 特别地,当v=m=1时,这两个分数微分变换约化的结果与通过外微积分获得的结果是一致的·
