尽管双层网格结构在产生自由形式和美观的设计方面具有明显的优势，但其应用中的挑战在于与其布局优化相关的计算成本和制造中的限制。Conway运算符是处理此类结构的有效工具，可生成复杂但美观的拓扑布局。本文提出了一种用Conway算子生成的双层网格结构的计算流程。在定义了应用的运算符之后，将根据结构设计规范对结构进行优化。这种布局的固有模块化显著减少了所需的计算资源，同时促进了制造过程。该工具被应用于文献中可用的现有结构上，在该结构上评估不同的拓扑。结果，实现了结构的总体质量的降低，同时获得了关于不同操作符的结构行为的有洞察力的信息。因此，强调了这一方法未来发展的潜力。
Despite the evident advantages of double layered grid structures to produce freeform and aesthetically pleasing designs, the challenge in their application lies in the computational cost associated with the optimization of their layout and limitations in their fabrication. Conway operators are an efficient tool for the manipulation of such structures, producing complex yet aesthetically pleasing topological layouts. This paper presents a computational workflow for the evaluation of double layered grid structures generated using Conway operators. After defining the operators applied, the structure is optimized in compliance with structural design criteria. The inherent modularity of such layouts significantly reduces the computational resources required, while at the same time facilitates the fabrication process. The tool is applied on an existing structure available in literature on which different topologies are evaluated. As a result, a decrease in the overall mass of the structure is achieved, while insightful information for the structural behaviour of the different operators is obtained. The potentials for future evolution of this approach are hence highlighted.
