摘要
针对目前常规武器的发展趋势以及对建筑结构局部破坏特点,文中尝试采用一种钢板泡沫铝复合结构,以降低框架底层柱的破坏程度,并通过理论分析和LS_DYNA有限元数值模拟的方法,研究了钢板泡沫铝复合减振层的抗爆机理以及对框架结构柱的保护作用。结果表明,钢板泡沫铝复合减振层具有较好的吸能减振效果,可以运用到地面军事工程结构防爆设计中去,以提高地面军事建筑的战时生存能力。
To the developing trend and close-up damage property of the conventional bomb, and the article has tried to reduce the destruction of frame column with compound structure with foam aluminum layer and steel panels. The article investigated the absorb energy property of the compound structure with foam aluminum and steel panels by means of the theory analysis and the simulation analysis of LS-DYNA program. The result show that the blast-resistant capability of a multi-layer compound structure is obvious, and it can be used to reduce the destruction of shock wave if it is added to the frame column. So the safety of military structure can be well improved.
