摘要: 基于静态穿深实验以及闪光X光摄像实验,开展不同作用时序下磁场对聚能射流稳定性作用机制的研究。根据所得实验结果,分析相同炸高、不同时序控制作用下磁场耦合作用对聚能射流侵彻威力的影响。结合聚能射流与侵彻通道形态之间的关系,获得不同工况下与强磁场耦合后聚能射流对靶板的侵彻孔形形态特性,并通过孔形特性来判断强磁场对聚能射流稳定性的影响机制。根据实验结果对比可知,在一定条件下,不同时序控制的磁场均可增加聚能射流的稳定性,聚能射流的稳定性增加主要表现为延缓连续聚能射流的断裂和抑制断裂射流颗粒的翻转。

Abstract: The craters penetrated by the the shaped charge jet (SCJ) coupling with the magnetic field are measured and analyzed to obtain the different stabilizing mechanisms of magnetic field enhancing SCJ stability at different stages. The characteristics of the craters penetrated by SCJ coupling with the magnetic field are analyzed through the static depth-of-penetration experiment and X-ray photograph, and then the coupling mechanisms of SCJ and magnetic field are researched based on the experimental results. The experimental results show that the coupling effect of magnetic field loaded at different timing could increase the SCJ stability under certain conditions, but the stabilization mechanisms are different, which mainly includes two aspects: the delayed breakage of continuous SCJ and the inhibited rotation of fractured jet particles.

Key words: shapedchargejet, magneticfield, stability, penetrationcapability
