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。
In order to study the spatial distribution of fragments during simultaneous detonation of multiple projectiles, by designing the simulated projectile itself and using the pine plate as the rectangular target, the spatial distribution rules of fragmentation formed by single projectile bomb and multiple projectile explosions were respectively carried out according to the requirements of the shooting range test The experimental study shows that the distribution of the projectile fragments scatter density is obtained in two cases, and the contrastive analysis of single-shot projectile and multiple projectile explosions is carried out. The results show that the fragment distribution of multiple projectile with the same projectile has the same rule as that of single projectile. However, in the vicinity of the projectile elastic axis, the distribution probability of multiple projectile fragments is smaller than that of single projectile.
