| 摘 要： | 根据空腔膨胀理论分析了动能战斗部侵彻混凝土时壳体表面法向和切向膨胀作用力,建立了战斗部受力计算模型,基于刚体运动学理论建立了动能战斗部侵彻运动微分方程,通过编程计算了不同落角和攻角情况下动能战斗部侵彻混凝土过程中的力学响应,获得了落角和攻角对动能战斗部最大阻力和最大阻力矩的影响规律,为战斗部的强度设计和跳弹性能研究提供了基础。

| Abstract: | Based on cavity expansion theory（ CET）, the vertical and parallel surface expansion forces of kinetic warhead are analyzed during penetrating concrete, the mechanics differential equation of the penetrating concrete of oblique kinetic warhead is established. Through compiled the computing program, the effect law of the maximal penetration resistance and moment of kinetic warhead are obtained by transferring terminal angle and attack angle during the oblique penetrating course, this paper provided a basis for study on the strength design and ricochet of kinetic warhead. |
