半穿甲舰炮弹药侵彻舰船靶板数值仿真研究

Numerical simulation research of penetration on warship target plate by naval gun semi-armor-piercing ammunition

研究了舰炮半穿甲弹对舰船靶板侵彻能力,采用LS-DYNA有限元软件对美海军奥托·梅拉127 mm和76 mm舰炮弹药临界跳弹、打击甲板和侧舷靶板进行仿真,结果表明:以300 m/s速度打击15 mmE36钢板条件下,127 mm弹的临界跳角为9.5°,76 mm弹为29°;从甲板和侧舷攻击条件下,两弹均具备穿透多层舰船靶板的能力。舰炮弹药攻击舰船目标,可考虑适当延迟舰炮弹药起爆时间,在其进入内部重要舱室时引爆,提高对船体的毁伤效果。

The penetration ability on warship target by naval gun semi-armor-piercing ammunition is analyzed.LS-DYNA finite element software is used to simulate the ricochet,attacking main deck and ship board by Oto Melara 127 mm and 76 mm naval gun ammunition.It is concluded that the critical ricochet angle of 127 mm and 76 mm ammunition is 9.5°and 29°when striking on 15 mm E36 plate in 300 m/s.Both ammunitions are able to penetrate several layers attacking from main deck and ship board.When attacking warships,it is considerable to delay initiation time properly,so the ammunition can enter central cabin for improving damage effect.
