So called cell structure is composed of a network of combined slid stems or solid plates to firm a porous Aid. An aluminum honeycomb, a typical cell structure composed of hexagonal cells walls, has very small nominal weight and is widely used for reinforcement of shell structures. In this project, the in-plane static and dynamic behaviors of aluminum honeycombs were investigated both experimentally and analytically. Particularly the effect of strain rates on the in-plane compression process and plastic collapse was investigated intensively by introducing a cell-male strain and a macro-sale strain. In experiments, a newly constructed impacting device was used and the compression process was measured using a laser velocimeter a high-speed video camera and strain gauges.On the other hand, by considering the fact that in-plane deformation is large for relatively small external bads, the she& absorption characteristics was examined in order to apply aluminum honeycombs for a at and gentle man-machine damper. Also, the vibration. characteristics was investigated in the relation to the dynamic behavior and shock absorption of aluminum honeycombs.As a result, very interesting behaviors of the in-plane compression process ware found and useful knowledge for development of honeycomb structures was obtained

所谓的细胞结构是由组合的滑动茎或实心板的网络组成，以固定多孔的辅助物。铝蜂窝是一种典型的由六边形孔壁组成的孔结构，其标称重量很小，广泛用于壳结构的加固。在该项目中，对铝蜂窝的面内静态和动态行为进行了实验和分析研究。特别是通过引入细胞雄性应变和宏观应变，深入研究了应变率对面内压缩过程和塑性塌陷的影响。在实验中，使用了新构造的冲击装置，并使用激光测速仪、高速摄像机和应变仪来测量压缩过程。另一方面，考虑到相对较小的外部力，面内变形较大的事实针对铝蜂窝结构轻柔的人机阻尼器的缺点，对其吸振特性进行了研究。还有震动。研究了铝蜂窝的动态行为和减震的特性。结果，发现了非常有趣的面内压缩过程行为，并获得了蜂窝结构开发的有用知识
