摘要

摘要: 7A04铝合金具有较高的强度-密度比，广泛应用于穿甲工程材料领域。在轻气炮上进行了平头和卵形钢杆弹体正撞击10 mm厚7A04铝合金板的实验研究，得到了两种弹体撞击7A04铝合金靶板的损伤形式和特性。使用高速相机记录了撞击过程并测得了弹体的剩余速度，得到了两种弹体撞击10 mm厚7A04铝合金靶板的弹道极限。实验表明，此种铝合金靶板抗卵形弹体正撞击的能力强于平头弹。

Abstract: 7A04 aluminum alloy with high strength-to-density ratio has been extensively applied for armour material domain. The projectiles normal impacting 7A04 aluminum alloy plates with 10 mm thickness was conduct by light gas gun, where blunt and ogival steel rod projectiles were involved. The damage modes and penetration characteristics of the 7A04 aluminum alloy targets were obtained. The whole impact process and the residual velocity were obtained by the high-speed camera system. The comparison of the initial velocity versus residual velocity between blunt-projectile penetration events and ogival-projectile penetration events indicated that 7A04 aluminum alloy plates own stronger resistance ability to ogival projectile impact than that of blunt projectile.
