摘　　要：为了研究蜂窝夹芯板在破片高速冲击下的防护性能,利用ABAQUS有限元软件对球型弹丸高速冲击夹芯板进行了数值仿真,研究了面板厚度、芯层高度、胞元壁厚和尺寸对抗冲击性能的影响,得到了不同几何参数的夹层结构其弹道极限速度和吸能情况.结果表明:与低速冲击情况不同,高速冲击下夹芯板损伤更为局部化,各部分的吸能贡献也有所改变,面板厚度对夹芯板抗冲击性能的影响比芯层的影响更为显著.最后以比吸能为主要指标得到了在高速冲击下能量效率更高的夹芯板设计尺寸.In order to study the protective performance of honeycomb sandwich panel under high-speed impact of fragments,ABAQUS finite element software was used to simulate the high-velocity impact of spherical projectile on sandwich panel.The effects of panel thickness,core layer height,cell wall thickness and size on impact resistance were studied,and the ballistic limit velocity and energy absorption of sandwich structures with different geometric parameters were obtained.The results show that,unlike the low-velocity impact,the damage of sandwich panels is more localized and the energy absorption contribution of each part changes.The impact of panel thickness on the impact resistance of sandwich panels is more significant than that of core layers.Finally,with specific energy absorption as the main index,the design size of sandwich panel with higher energy efficiency under high-velocity impact was obtained.
