Title The Armor-piercing Force Study of Typical Fragments Impacting Armor Plates
Abstract Fragmentation elements design is an important process in the design of killing warhead. The striking velocity of fragmentation elements toward certain target material, and the material, mass, and the outline dimension of the fragmentation elements determine the ultimate lethal power[1]. Dueto its high density, velocity maintaining and armor-piercing ability, theHung-Alloy fragment has gradually become preferential damage element ofkilling warheads. As fragmentation elements, Hung-Alloy preformedfragment can produce light armor targets’ penetration damage and detonatethem when penetrating into the targets. Generally the limiting penetrationvelocity is used to weigh the ability of penetration. Thus, the researchof Hung-Alloy fragments’ armor-piercing characteristics has veryimportant application value. By application of simulation software AUTODYN, this paper gets the penetration regulation (limiting velocity ofpenetration, penetrating residual velocity etc.) of several kinds of representative Hung-Alloy fragment penetrating into targets of different thickness at different striking angle. Studying on armor-piercing power of fragments, we can learn about the physics phenomenon of armor targets’damage and the penetration mechanism.

1 绪论 1．1 引言 随着弹药领域的发展，破片式战斗部已成为主要的战斗部类型之一，其利用高能炸药的爆轰作用促使壳体破裂，进而形成大量的高速破片，通过破片的高速碰撞、引燃和引爆作用毁伤目标，可以用于杀伤有生力量、无装甲或轻型装甲车辆、飞机、雷达以及导弹等武器装备。 按破片的生产途径， 破片式战斗部可分为自然、 预控和预制破片战斗部三种类型。就预制破片战斗部而言，其壳体和蒙皮之间填充的破片毁伤元形状也各异，如球形、方形、柱形、菱形等。 要评价破片式战斗部的毁伤威力，首先就要对其组成要素—破片毁伤元的穿甲能力进行研究。因此，本文主要研究不同形状的典型破片对装甲钢板的侵彻贯穿能力，为破片式战斗部的威力设计提供依据。
