摘要
蜂窝结构的力学或物理性能是决定其能否推广应用的关键。针对提出的一种新型组合蜂窝结构,围绕该蜂窝结构的抗冲击性能展开研究,构建了新型组合蜂窝的冲击模型,通过数值仿真,实现了新型组合蜂窝的中高速冲击过程,并与正六边形、正方形、三角形、Kagome蜂窝结构的中高速冲击仿真结果进行了类比,分析和比较了新型组合蜂窝受冲击时的能量吸收特性。研究结果表明,新型组合蜂窝在受到冲击时整体刚性较好,具有较强能量吸收能力,是进行轻量化设计的理想结构。
The popularization and application prospect of honeycomb structure depends on its mechanical or physical properties. The research in the paper is mainly focused on the impact resistance of a new type of supercell honeycomb structure. The impact model of the honeycomb structure is constructed, and the process of medium and high speed impact is accomplished through numerical simulation. Meanwhile, the simulated result is compared with those of regular hexagon, square, regular triangle and Kagome honeycomb structure under the similar impact conditions while the energy absorption property of the new type honeycomb structure is analyzed and illustrated during the process of impact. The research findings indicate the new type of honeycomb structure has good overall stiffness and strong energy absorption and is also an ideal structure for lightweight desien.
