摘　　要：通过工程计算和数值模拟的方法,求得槽齿杆弹和光滑杆弹侵彻半无限靶的侵彻深度,得出了等效杆等效直径关于绝对侵深的变化规律。分析了杆式穿甲弹的槽齿结构对侵彻的影响,对槽齿结构的侵彻机理做了分析研究,研究结果可为杆弹设计提供参考。By means of engineering calculation and numerical simulation,the penetration depth and the equivalent diameter of equivalent rod equivalent diameter are obtained. Based on this,the influence of slot tooth structure on penetration is discussed,and the penetration mechanism of slot tooth structure is preliminarily discussed. The conclusion can provide reference for design of rod and projectile.
