摘要
在轻气炮试验装置上对开孔泡沫铝的冲击衰减特性进行了试验研究 ,得出了在冲击波加载条件下开孔泡沫铝中的冲击波压力及波速随距离的变化关系曲线。结果表明 :开孔泡沫铝具有良好的冲击衰减性能 ,使冲击波压力在其中呈指数关系衰减 ,而波速则随距离呈线性关系衰减。
The property of shock weakening of open-cellular Al foams has been experimentally investigated with a compressed-air gun. The relations of the shock compressive stress and wave velocity to the distance in open-cellular Al foams were obtained under the condition of shock compressive loading. The results show that, open-cellular Al foams have a good shock weakening property, where the shock compressive stress weakens exponentially and the wave velocity weakens linearly with the distance.
