Abstract

Compression–torsion (CT) coupling in mechanical metamaterials has a high potential to be used for energy harvesting, sensors, and actuators. In current study, a novel CT metamaterial with cubic structure and oblique elements was designed and parametrically analyzed using finite element method. The golden section method was applied to identify the optimal structural features for torsional properties. The impact of varying the number of cells along longitudinal and transversal directions on torsional and mechanical properties of tessellated structures was examined. Experimental compression tests on samples fabricated by digital light processing (DLP) confirmed the validity of the simulations. Comparison of the optimized cubic structure with other similar structures in the literature highlighted its potential for adaptation to various applications through parametric study and multifunctionality properties. Finally, the tubular configuration of the developed CT unit cells was also parametrically studied.

用黄金分割法设计和分析压缩-扭转耦合超材料

压缩-扭转（CT）耦合在机械超材料中具有很高的潜力，可用于能量收集、传感器和致动器。本文设计了一种具有立方体结构和斜单元的新型CT超材料，并用有限元方法对其进行了参数化分析。采用黄金分割法确定最优扭转性能结构特征。研究了沿纵向和横向方向改变单元数对镶嵌结构扭转性能和力学性能的影响。对数字光处理（DLP）制作的样品进行压缩实验，验证了模拟的有效性。将优化后的立方结构与文献中其他类似结构进行比较，突出了其通过参数化研究和多功能特性适应各种应用的潜力。最后，对CT单元细胞的管状结构进行了参数化研究。
