中文摘要：

为了研究不同胞元拓扑结构蜂窝填充薄壁结构的力学性能差异,建立了4种典型胞元填充结构的数值有限元模型,采用参数分析方法研究了它们在不同胞元壁厚及撞击速度作用下的动态力学行为。研究结果表明：在受到异面撞击载荷作用时,蜂窝与薄壁结构之间存在较强的耦合效应,且交错排布三角形蜂窝与薄壁结构之间的耦合效应最强;在耦合效应与撞击载荷的综合作用下,交错排布三角形蜂窝填充薄壁结构的动态力学性能较其他3种结构更为优异;随着胞元壁厚、撞击速度的增加,蜂窝填充薄壁结构的承载能力、吸能能力和稳定性都有一定程度的提高。

英文摘要：

To study the difference of mechanical behaviors between honeycomb-filled structures with different topological configurations, the numerical finite models of four typical honeycomb filled structures were established, and the dynamic mechanical behaviors of these honeycombfilled structures with different cell wall thicknesses and impact velocities based on the parameter analysis method were studied. The results show that there is a strong coupling effect between the honeycomb and tube wall when subjected to the out-of-plane impact loading, moreover, staggered configuration triangle honeycomb-filled structure shows the strongest interaction effect; the dynamic mechanical behavior of staggered configuration triangle honeycomb-filled structure is the best under the interaction effect and impact loading; and it can be also found that the erashworthiness, energy absorption ability and stability of honeycomb-filled structure are improved with impacting velocity and cell wall thickness increasing.
