摘要

通过有限元数值模拟方法，对方孔蜂窝夹层板在爆炸冲击载荷下的变形机理和吸能特性进行了分析。在单位面积质量以及夹层板芯层薄壁间距、高度给定的情况下，通过对不同夹芯层相对密度下夹层板的吸能率以及上、下面板最大变形的比较，得出了最优的夹芯层相对密度。在此相对密度下，夹芯层吸能率最高，下面板变形最小，夹层板的抗冲击性能最优。同时还讨论了夹层板芯层薄壁间距、厚度、高度以及面板厚度对其各部分吸能率的影响，以得到最优化的夹层板结构。

Abstract

The deformation mechanism and energy absorption characteristics of the square honeycomb sandwich plates under blast loading are analyzed by the finite element numerical simulation method．With the given per unit mass，cell size and core height，by comparison of sandwich plates’s energy absorptivity and face sheets’s maximum deflection under different core relative density，the optimal core relative density of the sandwich plates is obtained．On this condition，the core have the highest energy absorptivity，the minimum deflection in the bottom face sheet and the sandwich plates have superior shock resistance．Furthermore，effects of geometrical parameters including cell size，core web thickness，core height and face sheet thickness on the energy absorptivity are discussed in the analysis to obtain optimal sandwich structure．
