| 摘 要： | 根据舰船上加筋板壳结构在强冲击载荷作用下的变形以及破坏过程,结合加筋板受弹丸穿甲的实验研究,采用数值模拟方式,对加筋板受到弹丸攻击时,靶板破坏模式、弹丸过靶姿态以及靶板抗穿透能力等进行了研究。结果表明,筋板的存在,使得靶板强度和刚度都得到了较大提高,靶板整体结构性能以及破坏模式发生了较大变化,"一""T""十"字加筋使弹丸极限穿靶速度的提高量随筋板和弹丸的不同在35%～80%之间变化,弹丸的最大偏转角达到了35°～40°。

| Abstract: | Based on the experimental perforation of projectile impacting stiffened plate, numerical simulations were conducted to study the failure pattern of target, projectile trajectory and the anti-perforation capability of target. The results show that stiffeners enhance the strength and rigidity of target, and change the whole structure capability and the failure pattern of target. For the single stiffened plate, single stiffened plate with "T" sectioned stiffener and cross stiffened plate, the increase of limit penetration velocity for different stiffeners and projectiles is 35%~80%. The maximum deflexion angle of projectile is 35°~40°. |
