| 摘 要： | 描述了带攻角长管体垂直侵彻半无限厚靶的物理图像,分析了"靶芯"力的大小和方向,建立了侵彻简化模型;给出了在不同的初始攻角条件下,管体在侵彻过程中攻角和穿深的变化规律.相同速度下,随着初始攻角的增大侵彻深度变小,基本呈线性关系.计算结果与实验结果吻合较好.

| Abstract: | The pattern of long tube with attack angle vertically penetrating into semi-infinite thick target was described.The size and direction of "residual core" force were analyzed.Simplified model of penetration was built.Under different attack angle,the variation regularity of attack angle and depth of the penetration was presented while tube penetrating into the plate.The penetration depth decreases with the increase of initial attack angle at the same velocity,which appears a linear relationship.The calculation results fit the experiment data quite well. |
