摘要(Abstract)：

鉴于泡沫铝材料良好的吸能特性和三明治型组合构件在强度、刚度上的优势,通过有限元分析软件ANSYS/LS-DYNA对钢板-泡沫铝-钢板三明治型组合板进行了装药量为10.0kgTNT的非接触爆炸数值模拟,考察组合板在爆炸荷载作用下的动力响应。研究表明:钢板夹泡沫铝组合板承受爆炸冲击波荷载时,响应方式主要为组合板整体弯曲变形和泡沫铝芯层局部压缩变形,芯层压缩变形是组合板吸收耗散能量的主要途径;适当地增加泡沫铝芯层厚度和面板厚度能够提高组合板的抗爆性能,同时使组合板充分发挥耗能作用。
Aluminum foam processes excellent performance of energy absorption and sandwich panels have advantages in strength and rigidity.So the sandwich steel panels with aluminum foam-core were researched by ANSYS/LS-DYNA.Non-contact explosion with 10.0kg TNT was simulated numerically and the dynamic response of panels under blast loading was investigated.The result showed that,the panels overall bending deformation and the aluminum foam-core local compression deformation were mainly dynamic response for sandwich steel panels with aluminum foam-core under blast loading.The core local compression deformation was the main way in consuming energy.If the thickness of the aluminum foam-core or the panel was increased,the anti-detonation performance would be improved,and it could help panels fully consume the explosive energy.
