摘　　要：为了获得由金属陶瓷复合单元构成的间隔装甲的抗侵彻性能,基于180 mm大口径聚能装药,开展了侵彻试验和仿真研究.通过分析靶板的破坏情况以及仿真中射流与靶板的相互作用过程,揭示了复合装甲对射流的干扰机制.采用剩余穿深等效准则,获得了不同着角下复合装甲的等效靶厚度.研究结果表明:斜侵彻条件下,金属陶瓷复合单元能够通过向射流头部施加不对称作用力,以及利用孔壁形成切割作用2种方式削弱射流的侵彻能力.同时,防护系数计算结果显示,在45°着角条件下,由金属陶瓷复合单元构成的间隔装甲具有良好的抗弹性能,可达到试验用聚能装药极限侵彻能力的1/4.In order to obtain the penetration resistance of the spaced armor composed of cermet composite elements,this paper carries out penetration tests and simulation study based on a large caliber shaped charge of 180 mm.By analyzing the destruction of the target plate and the interaction between the jet and the target plate in simulation,the interference mechanism of the composite armor on the jet is revealed.The equivalent target thickness of the composite armor at different angles is obtained by using the equivalent criterion of residual penetration.The results show that,under the condition of oblique penetration,the metal ceramic composite elements can weaken the penetration ability of the jet by applying the asymmetric force to the jet head and by using the hole wall to form cutting.At the same time,the calculation results of protection coefficient show that,under the condition of 45°angle,the interval armor composed of cermet composite elements has good anti-elastic properties,which can reach 1/4 of the maximum penetration capacity of shaped charge used in tests.
