通过3种罩型聚能装药结构的爆炸成形弹丸(EFP)对砖墙靶体的开孔效能试验研究,获得聚能装药结构对砖墙目标的开孔直径、开孔深度和开孔形貌.采用理论计算的方法获得爆炸成型弹丸的速度和系数C,从开孔效果和能量利用的角度分析,认为曲线+直线段组合罩结构对砖墙目标侵彻效果最为理想.
Three shaped charge structures were designed in this paper and the pre-hole experiments of masonry walls were carried out. The hole diameter, hole depth and hole morphology of masonry walls by shaped charge were measured. The velocities of EFP and parameter C were calculated by theory methods. From the point of pre-hole efficiency and energy-using, the shaped charge structure of curve and line segment has the best pre-hole effects.
