双锥药型罩结构参数对聚能射流的影响

为探究双锥药型罩结构参数对聚能射流速度的影响,采用数值仿真模拟双锥型药型罩形成射流的过程。结果表明:双锥药型罩较单锥结构形成的有效射流更加密集,且形成射流的头部最大速度及射流平均速度均大于单锥药型罩。通过因素影响分析结果可知,大、小锥罩角度的变化对射流头部速度影响均显著,且大、小锥罩角度差距越大,形成射流的平均速度越大,同时还能保持较高的射流头部速度。双锥罩罩顶距壳体起爆点距离越小,形成的射流头部最大速度越大,且侵彻深度越深;距起爆点越远,形成射流的平均速度越大,侵彻扩孔能力越强。

Influnce of structural parameters of the double cone shaped charge liner on shaped charge jet

In order to study the influence of the structure parameter of the double cone shaped charge liner on the velocity of the shaped charge jet, numerical simulation is used to simulate the process of the jet formed by the double cone shaped charge liner. The experimental results show that the effective jet is more dense than that of the single-cone structure, and the maximum velocity of the head and the average velocity of the jet are larger than the single-cone. The results show that the influence of the angle change of the shaped charge liner on the velocity of the jet head is significant, and the larger angle difference of the shaped charge liner, the larger average velocity of the jet is formed, and the higher jet head speed can be maintained. The smaller distance between the top of the double cone shaped charge liner and the shell, the greater maximum velocity of the jet head and the deeper penetration depth; the further distance from the initiation point, the greater average velocity of the formation of the jet and the stronger the penetration ability.
