镁合金靶板抗弹性能数值模拟

 质量是影响兵器装备实现战场快速反应能力的主要因素之一，因此现代高技术战争对兵器装备的质量指标提出了极为苛刻的要求。发达国家均投入巨资研究轻质结构材料以及与之配套的先进制造技术，以期减轻兵器装备质量，提高兵器装备的机动性，增加携弹量和野战辅助系统用量，提高士兵战场生存和作战能力。镁合金由于自身优点，成为兵器轻量化的理想材料。本文采用数值模拟方法，对AZ31B镁合金靶板的抗弹性能进行数值模拟研究，建立了3种不同类型侵彻体侵彻靶板模型，并给出了镁合金靶板被侵彻贯穿的一般过程。在铝合金和钢靶板面密度相同情况下，比较分析镁合金靶板的抗弹性能。结果表明，镁合金的抗弹性能较好，同时其抗弹性能与射弹参数、靶板厚度密切相关。

Numerical Analysis of Anti-penetration Property of Magnesium Alloy

The weight of weapons is a very important factor in the quick response capability in battlefield, it has paid much attention and strict requirements are posed in modern high technology warfare. The developed countries have invested huge amount of money in studies on lightweight structural materials as well as the advanced manufacturing technology to reduce the weight of weapons and equipment, improve their mobility, increase the number of bombs carrying and the amount of the field aid system and even improve the survival and combat capability of soldiers and weapons in battlefield. Magnesium alloy is an ideal material to be used in reducing the weight of weapons. In accordance with the ballistic performance of AZ31B magnesium alloy, three types of projectile penetration target plate models are established by numerical simulation. The general process of magnesium alloy being perforated is studied. The ballistic performance of magnesium alloy is analyzed comparing with aluminum alloy and steel made target plates under the same area density. It is shown that the ballistic performance is closely connected with the penetrator parameter and the target thickness.
