摘　　要：针对高速弹靶作用时穿甲弹芯发生变形及破碎的现象,设计一种两级分段弹芯结构,采用有限元仿真软件对两级弹芯结构侵彻陶瓷/钢复合靶板进行数值模拟。根据弹靶作用过程中的弹靶破坏模式、两级弹芯结构的运动规律,对侵彻过程进行阶段分析,并在此基础上探讨弹芯长度比例、间隔距离等因素对两级弹芯结构侵彻性能的影响。研究结果表明:两级弹芯结构较普通弹芯的侵彻深度增加率可达到16%以上;两级弹芯长度比例和间距对侵彻效果影响较大,选择合理的长度比例和间距有助于提高两级分段弹丸对陶瓷/钢复合靶板的侵彻性能;研究结果为两级分段弹芯的设计及应用奠定了基础。A two-stage segmented core structure is designed for the phenomena of deformation and fragmentation of armor-piercing core during the impact of a high-speed projectile on a target plate,and the finite element analysis software is used to numerically simulate the penetration of two-stage core structure into the ceramic/steel composite target plate.The stage analysis of the penetration process is carried out based on the damage pattern of target and the motion law of two-stage core structure,and the influences of core length ratio,spacing and other factors on the penetration performance of two-stage core structure are discussed.The results show that the increase in the penetration depth of two-stage core structure can reach more than 16% compared with that of the ordinary core.It is found that the length ratio and spacing of two-stage cores have a great influence on the penetration effect,and the selection of reasonable length ratio and spacing can help improve the penetration performance of two-stage segmented projectiles on ceramic/steel composite target plates.
