摘　　要：为了提高多爆炸成形弹丸(MEFP)对武装直升机、巡航导弹及空地制导武器等目标的毁伤能力,通过在炸药周向布置多个药型罩、轴向布置多层结构的办法,设计了一种新型多枚爆炸成形弹丸战斗部,分析了弹丸成型过程中的力学特性并利用动力学仿真软件模拟了成形过程。毁伤计算结果表明:该型战斗部所形成的单个EFP在穿透10 mm装甲后仍具有较高的剩余动能,对轻型装甲目标具有较高的毁伤效能,研究结果可为小口径MEFP战斗部设计提供参考。To strength the multiple explosively formed projectiles’（MEFP）damage effect on such targets like armed helicopters,cruise missiles and ground guided weapons,liners this paper designed were cir-cumferential layered with multi-layers along the axial.After the analysis on the EFP’s mechanical proper-ties during the forming process,the dynamic simulation software was adopted to reappear this forming process.De Marre formula calculation results show：the single EFP’s residual kinetic energy was signifi-cant even after it penetrated 10mm armor plate.The result of this paper indicates that MEFP warhead has impressive prospect to damage the abovementioned targets,and it will provide valuable reference for the Small-Caliber of the EFP’s warhead.
