多发弹丸同时起爆下破片空间分布实验研究

为了研究多发弹丸同时集中起爆时的破片空间分布规律,通过自行设计模拟弹丸,利用松木板作为长方形靶板,按照靶场试验要求分别对单发弹丸爆炸和多发弹丸爆炸所形成破片的空间分布规律进行了实验研究,得到了两种情况下弹丸破片飞散密度分布规律,并对单发弹丸爆炸和多发弹丸爆炸的破片飞散密度进行了对比分析研究.研究结果表明:多发弹丸爆炸时的破片分布与单发弹丸爆炸时的破片分布具有相同的规律,但在弹丸弹轴法向附近,多发弹丸的破片飞散密度分布概率小于单发弹丸.

Experimental Study on the Space Distribution Regularity of Fragments in Multi-projectiles Explosion

In order to study the space distribution regularity of fragments in multi-projectiles explosion,simulated shells were designed as the experimental projectiles,the space distribution regularity of fragments in multi-projectiles explosion and single projectile explosion were studied,by using the deal board as the quadrate target board.The distribution rule of fragments flight density were found and comparatively analyzed in the two cases.The research results showed that the space distribution regularity of fragments in multi-projectiles explosion and single projectile explosion either had something in common,while around radial direction of projectile axis,the distribution probability of fragments flight density in multi-projectiles was lower than that in single one.
