摘　　要：随着武器科技的发展,冲击波对掩体内部人员的伤害已经不能忽略。利用自行设计的爆炸实验研究了泡沫铝作为底板材料对爆炸冲击波在结构后产生的次生冲击波超压的衰减,并利用LS-DYNA模拟实验结果。通过数值模拟还研究了泡沫铝的排序结构对其防爆震效果产生的影响。The personnel injury inside shelter caused by the secondary shock overpressure can not be ignored along with the development of weapon. The attenuation of the secondary shock overpressure in air behind aluminum foam structure was studied by the designed explosion experiment equipment. Numerical simulation proved experiment results by LS-DYNA. The effect of different sequencing structure of layered aluminum foam and steel plate on anti-blast was investigated by numerical simulation.
