摘　　要：文中对不同碰靶速度下弹丸对不同靶弹直径比的圆柱形混凝土靶侵彻过程进行了模拟,通过对侵彻过程中弹丸加速度曲线的特点分析,得出可以忽略靶体侧面边界的最小靶弹径比与弹丸撞击速度的关系。并通过数据拟合,得出一个靶体设计参考关系式,可为侵彻混凝土试验的靶体设计提供参考。In this paper,projectile impacting different ratio of target-projectile diameter numerical simulation was conducted with the nonlinear dynamic analysis software. According to analysis of the acceleration curve,the relation between the maximum impact velocity and the minimum ratio of targer-projectilr diameter that the lateral boundary effect can be ignored was gained. We get the formula that deign of experimental targets by fitted for the calculation data. The results offered by this paper can provide some references for the design of penetration concrete targets.
