摘要
分析了空气中爆炸时挡波墙对冲击波的削波作用。结果表明 ,在爆源周围修一定高度和厚度的挡波墙可以把空气冲击波在挡波墙之后一定距离内的峰值压力削弱 2 0 %～ 30 % ,同时用数值模拟的方法计算了冲击波与挡波墙相互作用的过程 ,得到了在爆源周围有障碍物的爆炸场初始发展以及整个传播过程 。
The cut effect of gear wave wall on explosion in air is analyzed. The results show that the gear wave wall of certain height and thickness around the blast source can reduce the pressure of peak value by 20%～30% away from air shock wave after the wall. Mean while, the interaction between shock wave and gear wave wall has been calculated with the numerical simulation method.And initial development at the explosive site of barrier around the blast source, as well as entire spread course has been obtained by the numberical simulation. The calculated result basically coincides with the experimental results.
