摘要:
为研究爆炸成型弹丸(EFP)药型罩结构,基于爆轰波在有大直径隔板的EFP装药结构中的传播特性,建立了马赫波作用下罩顶微元压垮速度理论计算模型。理论计算结果表明,药型罩顶部局部加厚可以显著地降低罩顶微元压垮速度,避免EFP头部断裂; 当厚度增加量过大时会导致EFP头部出现射滴和包心,对EFP飞行稳定性和侵彻威力造成负面影响。数值模拟结果表明,罩顶局部加厚不会显著降低EFP速度和长径比; 当罩顶局部厚度增加量为12.5%~25.0%时,既能避免EFP头部断裂,又能避免EFP头部出现射滴和包心。对带隔板EFP战斗部进行了X光实验,实验结果验证了数值模拟结果的正确性。
Abstract:
An analytical model for calculating the collapse velocity of a liner element under the impact of Mach wave is proposed based on the characteristics of detonation wave transmitting in a charge embedded wave shaper of explosively formed projectile(EFP)to research the liner configuration.The theoretical results show that,local thickening of the liner top can reduce the collapse velocity of the top element significantly and avoid the damage at the nose of the EFP; the overmuch increment of the thickness of the liner top leads to droplets and hollows,and is adverse to the stability and the penetration capability of the EFP.The simulations reveal that,the EFP initial velocity and length-diameter ratio are barely decreased due to thickening the top of the liner; the thickness increment between 12.5% and 25.0% can inhibit the damage at the nose of the EFP and avoid droplets and hollows.The X-ray results are identical to the simulation results reasonably well.
