摘要: 着重对不同着靶速度下，弹体在刚玉块石混凝土中的侵彻情况进行了试验。研究结果表明，弹体的侵彻深度不随靶速度的提高而增加。这与弹体在普通混凝土和岩石中的侵彻现象明显不同，主要是由侵彻弹体发生破坏失去了继续侵彻能力造成的。而且，与普通混凝土或岩石相比，着靶速度越高，刚玉块石混凝土的抗侵彻性能越强。

Abstract: Nubbly corundum concrete is a new type defending material, whose anti-penetration characteristics can be affected by many factors. In this paper, the penetration of the nubbly corundum concrete by projectiles with different hit velocity is experimentally studied. The results indicate that the penetration depth does not increase with the increasing hit velocity, which is different from the phenomena of the penetration of concrete and rock. The main reason is that the projectiles are destructed and can not continue to penetrate. Moreover, the higher the hit velocity, the higher anti-penetration capability of the nubbly corundum concrete than that of common concrete or rock.
