侵彻钢筋混凝土过程中弹丸过载特性的实验研究

实验测试了侵彻钢筋混凝土过程中弹丸的过载情况,得到侵彻过程中弹丸的加速度时程曲线。通过将实验测得的加速度时程曲线按其本身的特点划分成四个部分,每个部分代表弹丸与钢筋混凝土作用的不同阶段,分析了不同阶段弹丸与钢筋混凝土相互作用的特点。实验结果表明,含筋率为2%的钢筋混凝土靶板的抗侵彻能力明显高于含筋率为1%的钢筋混凝土靶板。研究结果为理论模型的建立打下了基础,也可为相关弹药和防护工程的优化设计提供参考。

Experimental Study on Overload Characteristics of Projectile Penetrating Reinforced Concrete

In this paper,acceleration versus time data of projectile penetrating reinforced concrete were recorded.The data are helpful for comprehending the process of projectile penetrating reinforced concrete.The acceleration versus time data were divided into four parts.The interaction features of projectile and reinforced concrete are different in each part.It is great help to found the penetration model by comprehending these features.The results indicate that the concrete can withstand more violent penetrating as the steel-ratio is increased.The obtained overload data of projectiles can be helpful for devising armour-piercing projectile and defense engineering.
