摘要: 针对展开型定向战斗部主装药设计了一种聚焦结构，采用数值模拟方法，对比分析了不同起爆方式对破片飞散速度及飞散区域的影响特性，并对三维模型的爆轰波传播方式及破片飞散情况进行了分析。数值模拟结果表明，距轴线端点1/8处对偶起爆方式的聚焦效果最好；三维模型在球形爆轰波的作用下，可以很好地控制破片的轴向定向集中飞散。通过静爆实验验证了数值模拟结果的合理性。Abstract: The present numerical study is to investigate the explosive driven behaviors to the flight velocity and flight area of all the fragments of evolvable aimed warhead, and the propagating style of the detonation wave of the three-dimensional model. The results of numerical simulation demonstrate that the dual initiation that one eighth to the end of the axis has the best effect of the five initiation positions. Under the effect of the spherical explosive wave, the directional dispersion of the fragment of the three-dimensional model can be controlled well. The rationality of the numerical simulation was verified by the explosion experiments.
