摘要:
利用ANSYS/LS-DYNA仿真软件研究了药型罩曲率半径对双层药型罩EFP战斗部成形及侵彻特性的影响规律。数值计算结果表明，当药型罩曲率半径的相对值在0.67~0.93时，弧锥结合型双层药型罩EFP战斗部可成形具有良好外形的侵彻体;此时，成形侵彻体的最大侵彻深度约为1倍装药口径。试验结果表明，双层药型罩EFP战斗部成形侵彻体能够有效击穿2层2 cm厚45#钢靶，成形侵彻体对钢靶侵彻的开口形状近似呈现圆形，是具有相同装药结构EFP战斗部成形侵彻体侵彻深度的2倍左右。研究结果可以为双层药型罩EFP战斗部结构优化设计提供参考。
Abstract:
Influence of curvature radius on the formation and penetration of explosively formed penetrator (EFP) warhead of the double layer liner was researched by LS-DYNA software. Simulation results show that the penetrator has a good shape and the maximum penetration depth is about 1 time charge caliber when the relative value of liner curvature radius is located in 0.67-0.93. Experimental results also show that the penetrator could effectively breakdown two 2 cm thickness 45# steel targets and the entrance of the target is approximate in a circle shape. It is about twice penetration depth compared with EFP in the same shape charge structure.The conclusions can supply references for optimization of EFP warhead of the double layer liner.
