The penetration behavior is very important for the semi-armor-piercing warhead. The oblique penetration behavior of the projectile with cutting mechanism was studied numerically by using the finite element code LS-DYNA. The penetration performance of the projectiles with and without cutting mechanism were compared respectively on the limit ricochet angle, the residual velocity after perforation, the dimension of the hole and the sliding distance of the projectile on the target before perforation. It shows that the numerical results agree well with the experimental ones. It reveals that the anti-ricochet effect of the cutting mechanism on the projectile is not so obvious but the dimension of the hole created by the projectile with cutting mechanism is much larger than that of the traditional projectile. The deflection and attack angle of the projectile with cutting mechanism change to different extent compared to the case of the traditional projectile. An optimized projectile with half cutting mechanism was proposed, and the simulated results showed that the anti-ricochet ability of this optimized projectile is better.

侵彻靶板的行为对于半穿甲战斗部性能的发挥非常重要,利用LS-DYNA对带切割环球形弹体斜侵彻钢靶的行为进行了数值模拟。分别在跳弹临界角、靶板孔径、穿靶前弹体在靶板上的滑行距离及穿靶后弹体的剩余速度方面,对比分析了该新构型弹体与常规弹体的性能,数值模拟结果与实验结果吻合较好。研究发现,切割环在防跳弹方面的贡献并不明显,但带切割环弹体的穿孔尺寸远大于常规球形弹体。在斜侵彻钢靶的过程中,切割环使弹体的偏转及攻角出现了不同程度的变化。提出了一种半切割环弹体构型并进行了对比分析,结果表明,半切割环使弹体的防跳弹性能得到提升。

侵彻靶板的行为对于半穿甲战斗部性能的发挥非常重要,利用LS-DYNA对带切割环球形弹体斜侵彻钢靶的行为进行了数值模拟。分别在跳弹临界角、靶板孔径、穿靶前弹体在靶板上的滑行距离及穿靶后弹体的剩余速度方面,对比分析了该新构型弹体与常规弹体的性能,数值模拟结果与实验结果吻合较好。研究发现,切割环在防跳弹方面的贡献并不明显,但带切割环弹体的穿孔尺寸远大于常规球形弹体。在斜侵彻钢靶的过程中,切割环使弹体的偏转及攻角出现了不同程度的变化。提出了一种半切割环弹体构型并进行了对比分析,结果表明,半切割环使弹体的防跳弹性能得到提升。

The penetration behavior is very important for the semi-armor-piercing warhead. The oblique penetration behavior of the projectile with cutting mechanism was studied numerically by using the finite element code LS-DYNA. The penetration performance of the projectiles with and without cutting mechanism were compared respectively on the limit ricochet angle, the residual velocity after perforation, the dimension of the hole and the sliding distance of the projectile on the target before perforation. It shows that the numerical results agree well with the experimental ones. It reveals that the anti-ricochet effect of the cutting mechanism on the projectile is not so obvious but the dimension of the hole created by the projectile with cutting mechanism is much larger than that of the traditional projectile. The deflection and attack angle of the projectile with cutting mechanism change to different extent compared to the case of the traditional projectile. An optimized projectile with half cutting mechanism was proposed, and the simulated results showed that the anti-ricochet ability of this optimized projectile is better.
