Research on Creating Function of New Lightweight Core Structure and Its Forming Method by Fusion of Computational Mechanics and Origami Engineering

建立了基于空间填充几何和Origami操作的桁架芯体成形方法，并将其应用于工业实践，证明桁架芯体完全上级蜂窝芯体;提出了可展开折叠的反螺旋圆柱形Origami结构的成形方法，并证明该结构具有良好的吸能性能。映射变换由于能高效地生成复杂的折叠结构，使其在工业上的应用范围大大拓宽。最后，运用折纸理论，生成真实的复制模型，成为新产业的风口。

The forming method of truss core developed by space filling geometry and Origami operation was established, and its application to industry proved that truss core is superior totally to honey comb. The forming method of reverse spiral cylindrical Origami structure as deployable and foldable core was developed, and it was shown that the structure could be excellent energy absorption. Mapping transformation made the range of industry application widen, because it could generate efficiently the complicated folding structures. Finally, Origami theory is applied to generate real copy model which could become the spout of new industry.
