摘要:
为了有效地降低前舱对聚能射流的干扰作用，提高聚能战斗部侵彻混凝土靶的威力，设计了一种锥弧药型罩。利用动力学仿真软件AUTODYN2D对两种小锥段不同壁厚的锥弧药型罩和相同装药结构下的传统药型罩在前舱干扰情况下形成射流的过程进行数值模拟研究，分析这3种药型罩形成射流的性能，最后通过静破甲试验验证锥弧药型罩的侵彻性能。结果表明：与传统结构药型罩相比，在爆轰压力作用下，锥弧药型罩的锥形部分形成头部高速射流，减少在前舱的射流消耗，增加侵彻深度；弧形部分形成的射流质量利用率高，可形成粗大射流，提高侵彻能力；小锥段1.6 mm和2.5 mm壁厚锥弧药型罩形成的射流都能够侵彻1 200 mm厚的混凝土靶板，且小锥段1.6 mm壁厚锥弧药型罩形成的射流侵彻性能更好。
Abstract:
In order to effectively reduce the interference of forebay on shaped charge jet and improve the penetration power of shaped charge warhead into concrete target, a conical arc liner was designed. Jet forming process of two kinds of small-cone conical arc liner with different wall thickness and the traditional liner under the interference of forebay were numerically simulated by using the dynamic simulation software AUTODYN2D. Their jet forming performance were compared, and penetration performance of conical arc liner was verified by static armor breaking test. Results show that, compared with the traditional liner, under the action of detonation pressure, conical part of the conical arc liner forms a high speed jet at the head, which reduces the jet consumption in the forebay and increases the penetration depth. Mass utilization rate of the jet formed in the arc part is high, which can form a coarse jet and improve the penetration ability. The jet formed by small-cone conical arc liner with 1.6 mm and 2.5 mm wall thickness can penetrate 1 200 mm concrete target, and the jet formed by small-cone conical arc liner with 1.6 mm wall thickness has better penetration performance.
