摘要
为研究水下爆炸对鱼雷、水雷等水下目标的破坏机理开展了一次水下爆炸试验,采用长2.2 m、直径0.53 m的圆柱壳结构作为目标,采用1 kg标准TNT球形装药作为爆源在水平距离5.5 m处爆炸,测量了圆柱壳正面、背面和侧面的压力场,得到了冲击波时程曲线,测量及分析结果表明:正面和侧面由于反射波的影响均会发生截断效应,背面由于前驱波影响前段上升缓慢,当冲击波到达时迅速上升,之后以指数形式衰减,圆柱壳结构正面的冲击波冲量最大,侧面次之,背面最小,对于结构侧面的破坏作用最小。
To study the damage mechanism of torpedo and mine,underwater target explosion test was carried out,and taking a cylindrical shell,with length of 2. 2 m and diameter of 0. 53 m as the target and using 1 kg TNT as the standard spherical charge explosion sources in horizontal distance 5. 5 m,we measured the pressure field of cylindrical shell front on the back side and obtained shock wave curve. The results show that the front and side effects due to reflection occurs due to the truncation effect,and the back segment precursor effect rises slowly,and when the shock wave arrived after the rapidly rising exponentially,cylindrical shell positive shock wave reaches the maximum impulse,and the side and back is the smallest,and the destructive effect on the side is the minimum to structure.
