摘要
虽然单一的装甲钢或芳纶板具有良好的防高速弹丸贯穿性能,但采用复合结构可以大大提高单一防弹板的防弹效率,减轻防护板面密度。通过弹道实验和数值模拟方法研究了装甲钢复合芳纶泡沫夹层结构抗56式7.62mm普通钢芯弹贯穿特性;探讨了不同复合形式的装甲钢复合芳纶泡沫夹层结构抵抗弹丸的防护效能和影响防弹板吸收子弹动能的因素;提出了该种装甲钢复合芳纶泡沫夹层结构最佳防弹速度区间的概念和相应的V50估算公式,由此可以设计出防弹效费比最佳的防弹板。
Although the bullet-proof plates made by single armor steel or the armed fiber have good characteristics of anti-penetration to high-speed bullet, but the compound structure can greatly increase bullet-proof properties and reduce its area density. The propertities of penetration of the sandwich structure with foam and armor steel reinforced by the armed fiber under the 56 types with 7.62 mm common steel core bullet are studied by experiments and numerical analysis. The protective ability of anti-bullet and influence factors of the absorbing bullet kinetic energy have been researched through the different compound forms of foam sandwich structure. The concept of the best bul- let-proof speed zone and Vso homologous formula in the structure are given. So the bullet-proof plates with the best benefit-cost ratio can be designed.
