摘　　要：为了探究新型镍合金EFP的威力性能,研究了向后翻转型和向前压拢型2种成型方式下镍合金EFP的成型过程。基于侵深威力较优的向后翻转型EFP结构,分析了药型罩曲率半径、壁厚、侵彻速度和靶厚对侵彻威力的影响规律。研究发现:随着外曲率半径的增大,侵彻深度随之先增大后减小,孔径则先减小后增大;随着药型罩壁厚的增大,对靶板的侵彻深度先增大后减小,孔径逐渐增大;随着侵彻速度的提升,镍合金EFP对半无限靶板侵彻深度先增大后减小,孔径逐渐增大,对穿透薄靶后的后效靶的有效毁伤面积逐渐增大;而随着靶板厚度的增大,镍合金EFP对后效靶的有效毁伤面积逐渐减小。试验结果与仿真结果一致性较好,研究结论可为EFP战斗部结构设计提供关键技术借鉴。In order to explore the power performance of the new nickel alloy EFP,this paper studies the forming process of nickel alloy EFP under the two forming methods of backward turning and forward pressing.Based on the backward-turning EFP structure with better penetration power,the influence of curvature radius,wall thickness,penetration speed and target thickness on penetration power is analyzed.It is found that with the increase of the outer radius of curvature,the penetration depth increases first and then decreases,and the pore size decreases first and then increases.With the increase of the thickness of the liner,the penetration depth of the target increases first and then decreases,and the aperture increases gradually.With the increase of penetration speed,the penetration depth of nickel alloy EFP to semi-infinite target plate increases first and then decreases,the pore size increases gradually,and the effective damage area of the aftereffect target after penetrating the thin target increases gradually.As the thickness of the target plate increases,the effective damage area of the nickel alloy EFP to the aftereffect target gradually decreases.The experimental results are in good agreement with the simulation results.The research conclusions can provide key technical reference for the structural design of EFP warhead.
