【摘要】：采用25mm滑膛炮对2种靶体介质进行正侵彻试验,获得了着靶速度、侵彻深度、开坑直径以及开坑深度等参数.结果表明:侵彻深度随着钢筋混凝土配筋率的提高而略有降低,钢筋的掺加有利于提高靶体的抗侵彻能力;钢筋混凝土比素混凝土抗侵彻能力强,有较强抗2次打击的能力.利用DYNA软件模拟了当弹体以相同的着靶速度贯穿素混凝土靶和钢筋混凝土靶的过程,得到2种靶体抗侵彻能力的等效关系.
[Abstract]:The positive penetration test of two kinds of target media was carried out by 25mm shotgun, and the parameters such as target velocity, penetration depth, hole diameter and opening depth were obtained. The results show that the penetration depth decreases slightly with the increase of reinforced concrete reinforcement ratio, and the penetration resistance of target body is improved by the addition of steel bar, and the penetration resistance ability of reinforced concrete is stronger than that of plain concrete. The process of projectile penetrating through plain concrete target and reinforced concrete target at the same velocity is simulated by DYNA software. The equivalent relation of the two targets' anti-penetration ability is obtained.
