爆炸冲击波对反舰导弹发动机舱的毁伤效应

Damage Effect to Anti-Ship Missile Engine Cabin by Explosion Shock Waves

摘要:

为研究爆炸冲击波对来袭反舰导弹发动机舱的毁伤效应,应用ANSYS/LS-DYNA软件,对定量TNT和压装8701炸药爆炸产生的冲击波毁伤不同距离处的反舰导弹发动机舱进行了数值模拟。计算结果表明:爆炸冲击波对导弹发动机舱的毁伤以壳体凹陷为主要形式,对凹陷壳体周围区域几乎没有影响；爆炸冲击波对反舰导弹发动机舱的毁伤效应,随起爆点距离增加而迅速减小,且初期衰减速度明显大于后期。10 kg的装药量、炸点位于3 m处时,TNT和压装8701炸药对反舰导弹发动机舱基本无法造成毁伤。

Abstract:

For the study of explosion shock wave damage effect to incoming anti-ship missile engine cabin, using ANSYS/LS-DYNA software, the explosion shock wave of the quantitative TNT and press-fit 8701 explosives damage anti-ship missile engine cabin at different distances were simulated. The calculation results showed that the damages that the explosion shock wave to anti-ship missile engine cabin were mainly as the form of shell sag, and almost no effect on the area around the shell; the damage effect of the explosion shock wave to anti-ship missile engine cabin rapidly reduced with the increase of detonation point distance, and initial attenuation speed significantly greater than the late. 10kg of loading dose, when the burst point located at 3m, TNT and press-fit 8701 two kinds of explosives almost can not cause damages to anti-ship missile engine cabin.
