Experimental Studies on Structural Response and Mass Loss of High-Velocity Projectiles Penetrating into Reinforced Concrete Targets

  • 摘要: 设计了高速钻地结构弹,采用35 mm口径的弹道炮和100 mm口径的滑膛炮,进行了0.15和1.5 kg弹体在1 030~1 630 m/s速度范围内侵彻钢筋混凝土靶的实验研究,对高速侵彻条件下弹体的结构响应、质量损失及生存极限速度等问题进行了探讨。结果表明:在高速侵彻混凝土过程中,弹体结构的变形破坏包括头部侵蚀/墩粗+侧壁磨蚀、弯曲/尾部破裂、破碎等形式,弹体头部侵蚀和弹体质量损失程度随撞靶初速度的增加而增加。
