| 摘 要： | 为准确掌握截锥形弹体垂直穿透单加筋板后的打击深度,需要清楚知道弹体穿甲加筋板后的剩余速度.截锥形弹正穿甲板架,形成与截锥面相同的凿块,面板产生花瓣形破坏,腹板受到锥面的挤压发生塑性变形,翼板发生翻转,在此破坏模型基础上,确定板架的能量消耗方式.穿甲过程中,板架耗能主要通过凿块的剪切变形、凿块的动能、板架的挤压塑性变形、...

| Abstract: | In order to determine the impact depth of a conical projectile impacting single stiffened plate vertically,the residual velocity of the projectile after penetrating the stiffened plate must be known.The plug is formed after the conical projectile penetrating the grillage and the cross section of the plug is similar to that of the conical projectile.The petal failure is formed on the panel.By the squeeze of the conical projectile,the web plate occurs plastic deformation and the alar plate causes turnover.Bas... |
