摘　　要：为验证增材制造技术在周向MEFP战斗部领域应用的可行性,利用激光选区熔化(SLM)3D打印技术制备了以316L不锈钢为材料的壳-罩一体式周向MEFP战斗部,并开展了仿真和静爆试验研究。结果表明,3D打印316L不锈钢壳体在起爆后可以形成独立的多EFP毁伤元,其速度在1848~2112m/s之间,并能够在1.68m范围内保持完整的形态;受EFP自身速度梯度和药型罩材料延展率低的影响,多EFP毁伤元在2.7m范围外会出现不同程度的破碎;增材制造技术为周向MEFP战斗部的研究和制备提供了一种可行的途径,其打印精度完全能够满足战斗部设计需求,具有十分可观的应用前景。In order to verify the feasibility of additive manufacturing technology in the field of circumferential MEFP warhead,the shell-liner integrated circumferential MEFP warhead made of 316L stainless steel was prepared by SLM 3D printing technology,and the simulation and static-explosion test were carried out.The results show that independent multi-EFP reactive elements from the 3D printed 316L stainless shell are formed after initiation.The velocity of the reactive element is 1848-2112m/s,and the complete form is kept within 1.68m.Due to the influence of the EFP′s own velocity gradient and the low elongation rate of the liner,the multi-EFP reactive elements damage in different degrees away from 2.7m.The additive manufacturing technology provides a feasible method for the research and manufacture of the circumferential MEFP warhead,and its printing accuracy can fully satisfy the requirements of warhead design,which has a considerable application prospects.
