摘　　要：带隔板偏心的亚半球罩装药可形成杆式射流,为研究其成型及侵彻特性,以等质量原则设计了3种偏心的亚半球药型罩,开展杆式射流成型的X光试验及静破甲试验,对比不同变壁厚方式偏心亚半球罩杆式射流的成型形态及侵彻能力,找出了形成最佳杆式射流的药型罩变壁厚。研究结果表明,罩顶和罩口厚、中间薄形状形成杆式射流的杵体小,成型效果最佳,侵彻能力强,孔径均匀。通过理论研究杆式射流的成型参数,获得了杆式射流的速度和质量分布,罩顶和罩口部厚、中间薄形状药型罩形成杆式射流的质量较传统单锥罩提高22%,头部速度提高10%.In order to study the formation and penetration property of rod-like jet of eccentric sub-hemisphere liner shaped charge with foam,three eccentric sub-hemisphere liners are designed according to the equal mass principle,and X-ray imaging and penetration experiments are carried out. The formation effects and penetration capabilities of rod-like jets of different tapered eccentric sub-hemisphere liners are compared,and the optimal tapered liner mode for forming rod-like jet is acquired. The results show that the rod-like jet of the liner which is thick in top and bottom areas and thin in middle area has small slug,optimal formation effect,powerful penetration capability,and relatively homogenous penetration hole.The formation parameters of rod-like jet are studied by theoretical analysis,and the velocity and mass distribution of rod-like jet are obtained. Compared with traditional simple cone liner,the jet mass of the liner which is thick in top and bottom areas and thin in middle area is increased by 22%,and the tip velocity is increased by 10%.
