反舰导弹战斗部爆炸破片初速和空间分布

Research on fragment initial velocity and spatial distribution of anti-ship warhead explosion

为了研究反舰导弹战斗部破片的毁伤能力,首先分析战斗部破片形成原理。研究破片空间分布规律,以破片运动的基本公式为出发点,采用修正后的初速理论计算。利用数值模拟方法,模拟装药弹体爆炸实验,得到了弹体侵彻靶板后,破片的空间运动过程。结果表明:由于弹体各个部位厚度不同,产生的破片初速不同,空间分布也不同;同时也说明高速破片对人员和设备有很强的杀伤作用且作用范围大。

To research the damage ability of anti - ship missile warhead fragment, fragments formed theory is analyzed firstly. Fragments space distribution rule is researched and the revised theory calculation of fragment initial velocity at present is introduced on the basis of fragment motion formulas. Fragments space motion is analyzed after the missile penetrated target by using simulating ammunition missile explosion experiment in numerical simulation method. The result shows： each position thickness of shell body is different, fragments initial velocity and spatial distribution are different on account of each position different thickness of missile body, and it also explain that the high speed fragments have widely and strongly damage effectively on person and equipments.
