摘要
为研究碰撞位置对化学子母弹头毁伤效应影响,开展了爆炸成型大质量高速侵彻体碰撞化学子母弹头地面模拟试验。试验结果表明,化学子弹毁伤模式呈现为局部变形(不泄漏)、局部裂孔(部分泄漏)和碎裂摧毁(完全泄漏)3种形式,而且其分布显著受碰撞位置的影响。采用贯穿路径体积重叠法分析发现,子弹摧毁率随碰撞位置偏移量变化呈现复杂的类多阶梯分布,与试验结果相比,二者总体变化趋势相吻合。进一步机理分析认为,高速侵彻体沿贯穿路径对子弹的直接碰撞作用,只是造成子弹摧毁的一个重要因素,蒙皮碎片碰撞、子弹间相互碰撞以及子弹爆裂液体高速喷射等附加力学行为及效应也相当重要,显著提高了对化学子母弹头有效载荷的摧毁作用。
The ground-based experiments of high velocity explosively-formed penetrators impacting the simulated chemical submunition payloads are performed to investigate the effects of different impact posi- tions on the damage effect of chemical submunition. The experimental results show that the typical dam- age modes of chemical submunitions are denting （no leakage）, local cracking （ partial leakage） and fragmenting （complete leakage）, and their distribution strongly depends upon the impact positions in the submunition payload. An overlap volume analysis based on perforating trajectory shows that the destruc- tion probability of submunitions, varying with the impact position offset, appears a complex multiple step- like distribution. The analysis result is in agreement with the experimental result. It may be considered that the dynamic behavior and effect, resulting from the direct impact of high velocity penetrator upon the submunitions along the perforation trajectory, are the dominant destruction mechanisms. The other impor- tant additional destruction mechanisms, such as skin debris impact, collision among neighboring sunmu- nitions, submunition debris impact and leaked fluid ejection, significantly enhance the destruction effec- tiveness against the chemical submunition payloads.
