大装填比弹侵彻钢筋混凝土实验研究

Experimental investigation of lavge-loading projectile penetrating

设计了一种薄壁弹体,采用YOUNG方程预估该弹体侵彻混凝土靶板的侵彻深度,采用SAMPLL程序预估轴向过载。运用LS-DYNA软件分析弹体的侵彻过程,对材料力学性能进行实验研究。通过在130 mm气炮上的一系列弹体侵彻钢筋混凝土靶实验,考核了弹体的结构强度和侵彻深度。结果表明:弹体在低速侵彻钢筋混凝土靶板时结构不会发生破坏,300 m/s速度下具备侵彻贯穿600 mm钢筋混凝土层的能力。

A thin-walls projectile has been designed,and penetration depth of projectiles was evaluated by YOUNG Equation. Axial acceleration was evaluated by SAPLL. penetration process of projectile on penetrating concrete target was analysed by LS-DYNA. Mechanical Parameters of projectile material were studied by experiment. Penetration depth and structure intensity of projectile were examined by a series of experiments on penetrating concrete target on 4130 mm gas-gun. A conclusion is obtained, projectile isn＇t destroyed during penetrating concrete target, and reinforced concrete that is 300 mm in thickness was penetrated through.
