【摘要】:采用25mm滑膛炮對2種靶體介質(zhì)進(jìn)行正侵徹試驗,獲得了著靶速度、侵徹深度、開坑直徑以及開坑深度等參數(shù).結(jié)果表明:侵徹深度隨著鋼筋混凝土配筋率的提高而略有降低,鋼筋的摻加有利于提高靶體的抗侵徹能力;鋼筋混凝土比素混凝土抗侵徹能力強(qiáng),有較強(qiáng)抗2次打擊的能力.利用DYNA軟件模擬了當(dāng)彈體以相同的著靶速度貫穿素混凝土靶和鋼筋混凝土靶的過程,得到2種靶體抗侵徹能力的等效關(guān)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.
