| 摘 要： | 针对弹体高速正侵彻和斜侵彻混凝土/岩石半无限靶,基于考虑弹头质量磨蚀的弹体轴向阻力计算方法,结合弹体在非对称质量磨蚀及斜侵彻条件下所受的横向作用力,给出了高速弹体在正侵彻和斜侵彻两种状态下弹体结构屈服的分析方法,得到了在给定弹体壁厚条件下保持弹体结构稳定性的弹体极限初始撞击速度的要求,并讨论了不同的弹靶组合条件对弹体极...

| Abstract: | Aimed at normal and oblique penetration into semi-infinite concrete/limestone targets by a high-speed projectile,an axis drag force was employed to reflect the continuous variation of the nose shape.With considering the transverse load in the cases of asymmetrical mass abrasion and oblique penetration,a method was proposed to analyze the yield of a normally/obliquly penetrating projectile.The initial impact velocity limit was deduced by taking the projectile stability into account when the cartridge thickne... |
