摘　　要：开展了高速射流侵彻陶瓷/钢组合靶实验,并结合LS-DYNA仿真软件,研究了钢和陶瓷2种材料的不同组合形式对高速射流侵彻能力的影响规律;分析了高速射流对组合靶侵彻的破坏模式及侵彻机理。结果表明:陶瓷的加入会显著提升钢靶的抗侵彻能力;在相同的侵彻速度下,钢/陶瓷叠合靶的抗高速射流侵彻能力弱于间隔靶,表明空气间隔可以有效地干扰射流的侵彻能力。研究成果可为轻质防护装甲抗高速射流侵彻的设计提供参考。The experiments of high-speed jet penetrating ceramic/steel composite target were carried out,and the influence of different combinations of steel and ceramic on high-speed jet penetrating capability was discussed by using LS-DYNA simulation software.The damage mode and mechanism of high-speed jet penetration into composite targets were analyzed.The results show that the penetration resistance of steel target was improved by adding ceramic,and the penetration resistance of steel/ceramic composite target was weaker than that of spacer target at the same penetration velocity,it is shown that the air spacing can effectively interfere with the penetration ability of the jet.The research results can provide reference for the design of light protective armor against high-speed jet penetration.
