摘要
针对反应装甲日益广泛应用于装甲车辆防护的情况,提出了一种用于引爆反应装甲的小口径非金属药型罩聚能战斗部方案。在实验探究尼龙射流可以引爆模拟反应装甲的前提下,通过数值模拟的方法,对比5种非金属材料药型罩射流的成形情况确定了环氧树脂作为药型罩材料;以Held引爆判据为标准对炸高、药型罩壁厚、药型罩锥角以及罩顶内圆半径四个因素开展正交设计和极差分析,得到了非金属药型罩聚能装药对带壳装药起爆能力的影响程度结果,以及优化后的药型罩结构参数;基于优化结构的非金属药型罩聚能装药,对多种炸高下非金属射流冲击起爆反应装甲的过程进行了模拟。结果表明:非金属材料药型罩聚能装药能够形成形态良好、头部速度高的非金属射流,同时具有在多种炸高情况下引爆反应装甲的能力。研究结果可为非金属材料药型罩聚能战斗部的设计提供相关技术参考。
In response to the increasingly widespread application of reactive armor for armored vehicle pro-tection,a small-caliber non-metallic liner shaped charge warhead was designed for detonating reactive armor.On the premise that the nylon jet can detonate simulated reactive armor,through numerical simula-tion methods,epoxy resin was determined as the liner material by comparing the shaping of the jet forma-tion of five different non-metallic material liners.Orthogonal design and range analysis were conducted on the stand-off,liner thickness,liner cone angle and liner inner radius,using the Held detonation criterion,revealing the extent of the influence of non-metallic liner shaped charges on the detonation capability of shell-loaded explosives,as well as the optimized structural parameters of the liner.Based on the opti-mized non-metallic liner shaped charge,simulations were performed on the process of detonating reactive armor using non-metallic jets under various stand-off.The results show that the non-metallic material liner shaped charge warhead can form a well-shaped non-metallic jet with a high tip velocity,while also possessing the ability to detonate reactive armor under various stand-off.This provides relevant technical references for the design of non-metallic liner shaped charge warheads.
