摘要(Abstract)：

运用高速摄像技术探究钢壳平底、凹底雷管爆炸产物与破片的飞散规律,同时对不同管壳材质的凹底雷管反转弹丸的速度变化规律进行探究。研究表明:钢壳凹底雷管爆炸产物径向运动速度大于平底雷管;钢壳凹底雷管爆炸后,其聚能穴翻转变形产生反转弹丸,反转弹丸的头部速度在尾部拉应力的作用下逐渐下降;雷管爆炸95μs后,反转弹丸头部和尾部断裂,拉应力作用消失,头部速度骤然升高达到最大值;在距离雷管底部270mm内,钢壳凹底雷管反转弹丸的头部速度为1 440m/s,铜壳为3 204m/s,铝壳为6 350m/s。
The regularity of explosion products and metal fragment dispersion of detonator with steel shell concave and plain bottom was studied with high speed photography.The velocity regularity of reversal projectile produced by detonator with shell concave bottom made of different material was studied.The results showed that the radial velocity of explosion products of detonator with steel shell concave bottom was higher than detonator with plain bottom.The head velocity of reversal projectile generated after explosion of detonator with steel shell concave gradually declined under tail tensile stress.At 95μs after explosion,the head reversal projectile separated from the tail,the tensile stress disappeared and the head velocity burst to the peak.The distance to detonator bottom was 270 mm,in this range,the head velocity of reversal projectile of detonator with steel shell concave was 1 440m/s,the copper one was 3 204m/s and the aluminum one was 6 350m/s.
