摘　　要：为提升轻质装甲对聚能射流的防护性能,针对金属封装陶瓷结构的抗射流防护性能开展研究。以金属封装陶瓷结构为平台设计5种复合结构,通过LS-DYNA软件开展数值模拟,研究在不同倾角下各结构金属框架损伤程度、陶瓷夹芯的损伤范围及射流动能损失量。结果表明:与常规钢制装甲相比,金属封装陶瓷结构具有更好的抗射流侵彻性能,可降低结构的变形程度,将局部载荷分散至结构面内,降低陶瓷损伤范围,提升结构的防护性能;金属封装陶瓷结构可在面密度降低的同时造成比金属夹芯更高的射流动能损失量,并且在多种倾角情况下均表现出良好的防护性能。In order to enhance the protective performance of light armor against shaped-charge jet,the anti-jet penetration performance of metal-packaged ceramic structures was studied.First,three composite structures were designed based on metal-packaged ceramic structures.Then,numerical simulations were carried out using LS-DYNA to investigate the extent of metal frame damage,the shattered range of ceramic cores,and the kinetic energy loss of the jet at dif-ferent incidence angles.Results indicated that the proposed metal-packaged ceramic structures have better antijet penetration performance than steel armor.It can reduce the degree of structural deformation and disperse local loads to the structural surface,which reduces the damage range of ceramics and improves the protective performance of the structure.Moreover,it can reduce the surface density,while leading to higher kinetic energy loss compared to metal.The proposed structures exhibit good protective performance at many angles.
