摘　　要：为了考察弹丸在不同入射角侵彻过程的特性,利用有限元分析软件对弹丸过载环境进行数值模拟。通过分析得到弹丸侵彻过程中的弹体位移、过载加速度、应力曲线,揭示了弹体侵彻靶板的加载特性。结果表明:弹丸入射角越小,侵彻效果好,达到毁伤目标物目的;倾角越小弹头部受到损伤越大。In order to investigate the process of projectile penetration at different incidence angles characteristic analysis,finite element analysis software environment of the projectile is simulated of the overload.Obtained by analyzing the displacement of the projectile penetration process shot,acceleration and of stress overload curves,reveals the projectile penetrating the target plate load characteristics.The results showed that:the smaller the angle of the projectile,better effect of penetration,to damage the target goal.The smaller the angle,the greater of the damage of the Ministry of warheads.
