长杆射弹侵彻三种混凝土靶的实验研究

为了研究钻地武器的侵彻性能,在57mm口径的气炮上发射长杆射弹对三种靶体进行模拟侵彻实验。靶体为水泥砂浆石靶、钢纤维混凝土靶和含单层密排刚玉球的钢纤维混凝土靶。实验结果表明,弹头形状对侵彻深度有明显影响;当长杆射弹和撞击速度都相同时,与侵彻钢纤维混凝土靶相比,含单层密排刚玉球的钢纤维混凝土靶中的侵彻深度大约降低了11%,而水泥砂浆石靶中的侵彻深度增加了12%。

Experimental Study of the Long Rod Projectile Penetrating Three Kinds of Concrete Targets

In order to investigate the penetrating characteristics of earth penetrating weapons, a series of simulation experiments have been performed on 57mm diameter gas gun by launching long rod projectiles penetrating three kinds of concrete targets. These concrete targets are cement mortar, steel fiber reinforced concrete(SFRC) and the SFRC with a board made by tightly arranged corundum spheres inside. The experimental results indicate that the nose shape has important influence on the penetration depth, while targets are impacted by the same projectiles at the same velocity. The penetration depth into SFRC with the board is decreased about 11%, but the penetration depth into cement mortar is increased about 12% as compared with that into the SFRC.
