船体装甲外板抗穿甲数值仿真研究

Numerical Simulation on Anti Penetrating of Hull Armored Outer Plate

水面舰艇是现代海战中不可或缺的重要组成部分,通过开展典型反舰导弹战斗部对船体装甲外板抗穿甲数值仿真分析,用剩余速度和偏转角来评价船体装甲外板抗穿甲性能,得到了装甲外板板厚、水平构件规格、球扁钢间距等因素变化对装甲外板抗穿甲性能的影响规律,以及战斗部仰角、偏角的变化对装甲外板抗穿甲性能的影响规律,为船体装甲外板的防护设计提供一定的参考。研究表明:适当增加板厚,可以提高装甲外板的整体抗穿甲性能;适当将装甲外板设计成纵倾和横倾,可以有效提高装甲外板的防护效果。

Surface ship is an indispensable part of modern naval warfare. Through anti penetrating simulation analysis of a typical anti-ship missile warhead of hull armored outer plate, using residual velocity and defection angle to evaluate the anti penetration performance of the hull armored outer plate, obtaining the infuence on anti penetrating performance of the armored outer plate due to the change of armored outer plate thickness, horizontal component specifications, the distance of bulb steel, elevation and declination of warhead. It concludes that increasing the thickness of plate properly can improve the overall anti penetrating performance of the armored outer plate; designing the armored outer plate into trim and heeling properly can efectively improve the protective efect of the armored outer plate.
