摘要
利用轻气炮进行弹体斜侵彻钢筋混凝土的试验研究.通过高速摄影系统及靶前镜面反射装置记录弹体着靶前飞行姿态,得到了弹体对钢筋混凝土靶的斜侵彻破坏效应、弹道轨迹、弹体侵彻深度、开坑直径及弹体横向偏转等参数.试验结果表明,在一定速度下,倾角越大,靶面破坏范围及弹体横向偏转越大,侵彻深度越小,当倾角增至一定角度后发生跳弹现象.钢筋的加入对弹体斜侵彻开坑、破坏范围及弹道偏转有重要影响.
The non-normal penetration into reinforced concrete by gas guns was studied in the present paper, High velocity camera and mirrors in front of the target, are used to record the information about the projectile. The destructive effect, depth, crater diameter and ballistic trajectory of oblique penetration were obtained from the tests. It reaches the conclusion that deflexion of the projectile increases with the in crease of the obliquity angle, while the penetration depth decreases. The effect of reinforcement in oblique penetration tests has been analyzed.
