摘　　要：用某火炮发射长径比为 1 .5且着速在 1 30 0m/s左右的钢弹丸侵彻大间隔多层A3薄钢靶板的方法 ,对钢弹丸侵彻多层大间隔靶板的作用过程及其机理进行了分析和数值模拟 ,得到了较好的一致性。实验结果和数值计算分析表明 ,所设计的弹丸对多层间隔靶具有较强的侵彻能力 ,为以后类似弹丸的设计提供了参考。High speed steel projectiles with L/D=1.5 were launched at impact velocities of 1 300 m/s by a cannon.It penetrated thin A3 steel spaced metal plates with big space. The process and principle of steel projectiles against multi layer plates with big space was analyzed and simulated. The numerical results give a good agreement with experimental results. The results indicate that the projectile has stronger penetration against spaced targets and provides important parameters for designing such projectiles.
