基于毁伤度的多层复合目标内爆毁伤评估

机场跑道是典型多层复合目标,有效打击机场跑道可达到夺取制空权的目的。针对弹丸爆炸毁伤机场跑道,建立仿真计算模型,弹丸接触跑道表面后分别延时0.1ms、0.2ms、0.3ms、0.4ms起爆,采用毁伤度对机场跑道内部爆炸进行毁伤分析。仿真结果表明:随着引信延时增加,弹丸侵彻深度增加,机场跑道内部完全毁伤部分先增大后减小。对于文中这种结构机场跑道,在第二层混凝土层内起爆,毁伤效果最优。

The airport runway is a typical multi-layer compound target.The purpose of air control can be achieved by effectively attacking the airport runway.Aiming at the damage of airfield runway by projectile explosion,the simulation calculation model is established.After the projectile contacts the runway surface,the delay time is 0.1ms,0.2ms,0.3ms and 0.4ms respectively.The damage degree is used to analyze the damage of the internal explosion of the airport runway.The simulation results show:with the increase of fuze delay,the penetration depth of projectile increases,and the complete damage part inside airport runway first increases and then decreases.For the airport runway with this structure,the damage effect is the best when it is detonated in the second concrete layer.
