摘要

为了提高B4C/Al复合靶板抗弹性能,利用LS-DYNA对12.7 mm弹丸在600 m/s、700 m/s和800 m/s的速度下垂直侵彻B4C/Al复合靶板的过程进行数值模拟分析。研究了侵彻复合靶板过程中弹丸的速度变化和受力情况。计算结果表明:弹丸以600 m/s和700 m/s速度侵彻复合靶板时,异形 B4C/Al复合靶板比普通B4C/Al复合靶板有更良好的抗弹性能;弹丸以800 m/s速度侵彻复合靶板时,迎弹面为三角形的异形 B4C/Al复合靶板有较优的抗弹性能。

Abstract

In order to improve the anti-ballistic performance of B4C/Al compound target, LS-DYNA was used to simulate the whole process of 12.7 mm projectile penetrating B4C/Al compound target vertically at the speed of 600 m/s、700 m/s and 800 m/s. The velocity and force of projectile penetrating compound target are studied. The results show that when the projectile penetrates the compound target at speeds of 600 m/s and 700 m/s, the abnormal B4C/Al compound target has better anti-ballistic performance than the ordinary B4C/Al compound target; when the projectile penetrates the compound target at speeds of 800 m/s, the abnormal B4C/Al compound target with triangular front surface has better anti-ballistic performance.
