Some models were designed where the unique tetragon and hexagon grids borrowed from the wing structure were used as the basic elements, these models were analyzed numerically, it is shown that the model consisting of tetragon grids is much stiffer than that consisting of hexagon grids, while, more material is used in the first model;crinkling models based on tetragon grids or arched models consisting of hexagon grids become more stiffer than flat ones;hybrid models consisting of tetragon grids and hexagon grids can realize a proper balance between material saving and stiffness improving.

分别提取四边形、六边形的基本网格，建立结构模型，并对它们进行非线性数值分析。研究发现：四边形网格结构刚度大，六边形网格结构刚度小；而从材料利用率角度来讲，六边形网状结构更省材料；起皱对四边形网格结构刚度有加强，而起拱对六边形网格结构刚度有提高；如果将四、六边形的网格进行合理搭配，可以使结构刚度和材料利用率得到优化。
