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.To establish the equivalent relationship of anti-penetration behavior of reinforced concrete and plain concrete, some parameters, such as initial velocity, penetration depth, crater diameter and carter depth were established by means of 25 mm smoothbore gun. The results show that penetration depth de- creases slightly with the increase of reinforcement ratio, the addition of steel bars is beneficial to improve the penetration resistance of concrete. DYNA software is used to simulate at the same vertical velocity penetration and perforation of concrete and reinforced concrete, the equivalent relation of thickness is ob- tained.
