通过爆炸试验研究了铝蜂窝复合板的爆炸缓冲性能。在一系列的试验中，通过将铝蜂窝复合板设置在受到近距离爆炸的钢板上来检验爆炸缓冲效果。采用C-4炸药对钢板或铝蜂窝复合板进行了局部爆炸压力试验。改变缩放距离以研究缩放距离对缓解效果的影响。试验结果表明，爆炸压力分布对缓蚀效果有显著影响。讨论了爆炸冲击波作用下铝蜂窝复合板的屈曲区域与爆炸特性的关系。
This study investigated blast mitigation performance of an aluminum honeycomb composite panel by conducting explosion tests. In a series of tests, the blast mitigation effect was examined by setting the aluminum honeycomb composite panel onto a steel plate subjected to close-in explosion. Composition C-4 explosive was used to impose the explosive pressure locally to a steel plate or the aluminum honeycomb composite panel. The scaled distance was varied to investigate the effects of the scaled distance on the mitigation effects. Test results revealed that the explosive pressure distribution significantly affected the mitigation effect. The relationship between the buckling region of the aluminum honeycomb composite panel and the blast characteristics was discussed.
