摘要
对聚能装药用多点环形起爆器的同步性能和环形起爆的聚能装药侵彻钢筋混凝土的侵彻威力进行了研究。应用高速摄影技术和光纤探针技术测量了多点环形起爆器各点输出的同步性,结果表明环形起爆器各点输出同步性好,时间差最大不超过0.1μs;聚能装药对钢筋混凝土的侵彻威力实验结果表明,采用多点环形起爆器的聚能装药对钢筋混凝土的侵彻威力比点起爆的有较大提高。
A series of experiments were conducted to investigate the synchrony of the multi-point ring initiator applied to a shaped charge and the penetration capability of the shaped charges with the multi-point ring initiators into reinforced concrete targets.The output synchrony of all points of the multi-point ring initiator was measured by using the high-speed photography and fiber probe technique.It is showed that the output synchrony of all points is good and the longest time difference is less than 0.1 μs.The shaped charges were initiated to penetrate into reinforced concrete targets by applying the multi-point ring initiators and the central point initiation,respectively.Comparison of the experimental results shows that the multi-point ring initiators can improve markedly the penetration capability of the shaped charges.
