Abstract

In order to investigate the influence of attitude deflection on penetration ability of the bar penetrator projectile during oblique penetration of concrete target at high speed, LS-DYNA finite element software was used to numerically simulate the bar penetrator projectile penetrating concrete at 0°~2° attack angle and 0°~20° angle at two typical speeds (3Ma and 5Ma). The failure process of the target plate is analyzed, and the influence of attack angle and impact angle on penetration depth, channel deflection angle and angular velocity is summarized. The results show that the larger the angle of attack and the angle of impact, the smaller the projectile penetration velocity, the smaller the penetration depth and channel deflection angle, the higher the peak of the projectile angular velocity, and the earlier the peak time. However, the influence of the angle on the decreasing rate of projectile penetration depth shows a trend of first increasing and then decreasing at high speed. The research results have certain reference significance for the design of ground penetrating warheads.
