基于三角形和六边形蜂窝结构面内冲击性能的研究，该文探讨了面内冲击荷载作用下组合Kagome蜂窝结构的变形机制和能量吸收特性。首先，在保证蜂窝结构胞元厚度与边长尺寸比值不变的前提下，分析了不同形状胞元及其组合结构的动态冲击性能，给出了试件宏观及微观胞元结构的动态演化过程。在此基础上，探讨了冲击速度和相对密度一定情况下单位质量不同蜂窝结构的能量吸收特性。其结论将对蜂窝材料微拓扑结构的动力学优化设计提供指导。

英文摘要：

Based on the study of triangular and hexagonal honeycombs, the full-scale deformation mechanism and energy absorption properties of supercell Kagome honeycombs under in-plane dynamic crushing are discussed in the paper. Firstly, under the assumption that the ratio of the edge thickness to the length keeps constant, the in-plane dynamic properties of the honeycombs with different cell shapes, and the combination structures are numerically analyzed. The full-scale in-plane dynamic crushing of the specimen, as well as the micro-structure dynamic evolution during the deformation is given. Then, under the conditions that the crushing velocity and relative density are all the same, the energy absorption abilities of different honeycomb structures are researched. The results will provide helpful guidance in the dynamic optimum design of micro-topology structures of the honeycombs.
