该文通过对带铝套管的分段弹侵彻半无限钢靶的研究分析，以流体动力学和侵彻力学为基础，提出了一个分段弹垂直侵彻半无限厚靶的简化模型。模型既考虑了分段体的刚性侵彻，也考虑了铝套管的作用，能较好地预测分段弹的侵彻，包括分段弹的侵彻规律和间隔大小、碰靶速度等因素对侵彻的影响，计算也表明在１８００～２０００ｍ／ｓ的速度范围内，分段弹的侵彻能力较连续杆有明显提高。
Based on the research and analysis of semi-infinite steel target penetrated by the segmented projectile with aluminum casing, based on the fluid dynamics and penetration mechanics, a simplified model for vertical penetration of semi-infinite thick target by segmented projectile is proposed. The model not only considers the rigid penetration of the section body but also considers the function of the aluminum casing, which can predict the penetration of the section projectile well, including the penetration law of the section projectile and the size of the gap and the target speed The impact on the penetration, the calculation also shows that in the speed range of 1800 ~ 2000m / s, the penetration efficiency of the segment projectile significantly improved than the continuous rod.
