基于对混凝土侵彻孔径要求的聚能装药设计

Design of Shaped Charge Based on Demand of Crater Diameter of Perforation Concrete

文中给出了串联战斗部前后级匹配设计方法。根据破/爆型串联战斗部作用原理,为了使后级子弹可靠随进,前级聚能装药穿孔保持为圆柱形孔为好。文中根据能量守恒原理及侵彻孔径公式,推导了获得圆柱形穿孔的射流直径与速度的关系。借助数值计算手段进行了前级聚能装药的优化设计,并通过了试验验证。

Design method based on cylindrical hole of perforation concrete for precursory shaped charge of tandem warhead is presented in this paper. For the later kinetic energy projectile following reliably, the hole perforated by precursory shaped charge is cylindrical as well. The law conversation of energy and the hole diameter formula of jet perforating are employed to deduce the relationship of diameter and velocity of jet for cylindrical hole of perforation concrete. Numerical simulation program is applied to optimize precursory shaped charge. It is validated by experiments.
