摘    要：柱状药包置于一个盛满水的小薄壁圆柱筒的中央进行爆炸,药包中传播的爆轰波与水相互作用,在水中产生爆炸应力波;应力波从水中透射到圆筒,使得圆筒产生环向变形;用超动态应变测试系统测定圆筒外壁上的环向爆炸应变波,根据应变波的峰值与爆轰压力之间的关系,可以确定柱状中空药包爆轰压力的近似值,本文介绍了测试方法及测定结果。

Abstract: Explosive strain wave,resulting from the explosion of a cylindric charge centred in athin-wall cylinder containing water,transmits the cylinder. The wave emerging from theoutside wall of the cylinder is measured with an ultra-dynamic strain test system,and the ap-proximate value of detonation pressure is determined according to the relationship betweendetonation pressure and the peak value of the wave. In the paper,both the testing methodand testing results are described.
