为有效评估预制破片战斗部的毁伤效能,文中针对空中目标进行了动态毁伤威力研究。根据预制破片战斗部的结构特点,从爆炸瞬间的运动初始状态出发,建立了破片群的空间运动模型,并基于Matlab仿真得到了确定时刻对应的破片群空间分布规律及其相应的破片状态。结果表明,在总质量一定的前提下,45mm的预制破片的装填数量多,爆炸初速和动态飞散角大,并且在15ms后飞行距离较远。仿真结果可以为该型预制破片战斗部的总体优化提供理论依据。

For effective damage assessment of preformed fragment warhead, the dynamic damage power model for the antiaircraft was studied in this paper. Firstly, according to the structure characteristics of a typical columned preformed fragment warhead, under the condition of initial motion state, the spatial motion model was founded. Then, the spatial motion law and the fragment state of certain columned preformed fragment warhead were calculated and analyzed with Matlab. The simulation reveals that more of the $5mm warhead project is loaded than the $7mm. Besides, the initial velocity and dynamic dispersion angle are higher, and it flies farther at 15ms. The results can provide some helpful references for overall optimization of that warhead.
