In this paper a new virtual process chain is presented that allows a fast mechanical characterization of foldcores under flatwise compression. The aim is to find the best possible folded configuration with limited overall geometry dimensions providing highest mechanical properties for strength and stiffness under compressive loading. For this purpose an optimization method using the finite element analysis has been developed and validated against physical test results. Finally, the applicability of the presented method is evaluated for Miura-ori, derivatives of the Miura-ori and curved folds, while ensuring manufacturability remains feasible.

虚拟过程链，用于在平面压缩下优化三明治折芯

在本文中，提出了一种新的虚拟过程链，该链允许在扁平压缩下对折芯进行快速机械表征。目的是在有限的整体几何尺寸下找到最佳的折叠结构，从而在压缩载荷下提供最高的机械性能，以实现强度和刚度。为此，已经开发了一种使用有限元分析的优化方法，并针对物理测试结果进行了验证。最后，在确保可制造性仍然可行的情况下，评估了本方法对Miura-ori，Miura-ori衍生物和弯曲褶皱的适用性。
