这项工作提出了创新的折纸优化方法，用于复杂的折纸镶嵌，可用于可展开结构的设计的单位单元的设计。用于创建折纸瓦片的设计方法利用了应用于折纸折痕图案的基础结构的离散拓扑优化的原理。初始设计空间显示了所有可能的折痕，并给出了所需的输入和输出力。考虑到前川和川崎定理的可折叠性约束，该算法指定折痕为主动或被动。几何约束从目标3D对象定义。这个单元格的周期性复制使我们能够创建用于创建可展开庇护所的镶嵌。结构健全的镶嵌的设计要求进行了讨论，并用于评估我们的结果的有效性。未来的工作包括应用的单位细胞和镶嵌设计折纸启发机制。将特别重视可自行部署的结构，包括自然灾害避难所。
This work presents innovative origami optimization methods for the design of unit cells for complex origami tessellations that can be utilized for the design of deployable structures. The design method used to create origami tiles utilizes the principles of discrete topology optimization for ground structures applied to origami crease patterns. The initial design space shows all possible creases and is given the desired input and output forces. Taking into account foldability constraints derived from Maekawa’s and Kawasaki’s theorems, the algorithm designates creases as active or passive. Geometric constraints are defined from the target 3D object. The periodic reproduction of this unit cell allows us to create tessellations that are used in the creation of deployable shelters. Design requirements for structurally sound tessellations are discussed and used to evaluate the effectiveness of our results. Future work includes the applications of unit cells and tessellation design for origami inspired mechanisms. Special focus will be given to self-deployable structures, including shelters for natural disasters.
