【摘要】 为验证增材制造技术在爆破战斗部领域应用的可行性，采用选择性激光熔化(selective laser melting, SLM)技术，制备了以316L和17-4PH不锈钢为材料的仿生夹层圆柱壳体以及等质量均质壳体。通过静爆威力对比试验，对超压、比冲量及破片特性进行综合分析。试验结果表明：在相同装药情况下，17-4PH仿生夹层圆柱壳体较316L仿生夹层圆柱壳体超压高，且随距离增大，17-4PH仿生夹层圆柱壳体的比冲量也高于316L仿生夹层圆柱壳体；此外，两种材料的夹层壳体破片均展现出一定的杀伤效应，其中17-4PH仿生夹层圆柱壳体的破片平均速度高于316L仿生夹层圆柱壳体。与等质量均质壳体相比，仿生夹层圆柱壳体的超压表现相当。研究结果为新型爆破战斗部的设计与应用提供了有价值的参考，显示了增材制造技术在战斗部领域的广阔应用前景。更多还原

【Abstract】 In order to verify the feasibility of the application of additive manufacturing technology in the field of penetration warhead, bionic sandwich shell warhead and homogeneous shell warhead made of 316L and 17-4PH stainless steel were prepared by selective laser melting(SLM). The overpressure, specific impulse and fragment fragmentation were analyzed comprehensively through the static explosion power comparison test, in combined use of the peak overpressure and high speed photography technology. The test results show that under the same charge, the overpressure of 17-4PH bionic sandwich shell warhead is higher than that of 316L bionic sandwich shell warhead, and the specific impulse is also higher than that of 316L with the increase of distance. The fragments of the sandwich shell of the two materials have a certain killing effect on the target, and the average fragment speed of the 17-4PH sandwich shell warhead is higher than that of the 316L sandwich shell warhead in the two tests. The overpressure of the homogeneous shell warhead is similar to that of the sandwich shell. The additive manufacturing technology provides a feasible way for the research and preparation of explosive warhead. Its printing accuracy can fully meet the requirements of warhead design, and it has a very considerable application prospect.更多还原
