摘　　要：设计并制作了半球头柱形导弹战斗部模型,研究其爆炸后的毁伤载荷特性。通过试验,揭示爆炸后冲击波载荷特性,并对侧壁和端部壳体碎裂后的破片载荷特性进行比较,阐明冲击波和破片的作用次序。研究表明,在半球头柱形战斗部爆炸时,相同爆距下,战斗部侧壁处所形成的冲击波强度高于端部处约20%,侧壁壳体破碎形成的破片侵彻能力远大于端部;对于半球头柱形导弹战斗部,侧壁正对目标结构时产生的毁损威力远大于端部对准条件下的毁损威力。To study loading characteristics of a hemisphere-nosed warhead after explosion,models of this type of warhead were designed and fabricated,and explosion experiment was carried out.We revealed load characteristics of shock wave after explosion,comparatively analyzed load characteristics of fragment coming from cylindrical casing and far end,and illustrated coupled action of shock wave with fragments Our results show that under hemisphere-nosed warhead explosion,the shock wave intensity near cylindrical casing is roughly 22%higher than the far end at same distance.Fragments from cylindrical casing have a stronger capacity of penetration than that from the far end,which can penetrate Q235 steel plates with thickness of 10.18 mm,5.54 mm respectively.Therefore,for the hemisphere-nosed warhead,serious damage may occur on the structure when cylindrical casing near the target.
