摘　　要：设计了高速钻地结构弹，采用35mm口径的弹道炮和100mm口径的滑膛炮，进行了0．15和1．5kg弹体在1030～1630m／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。A high-velocity earth-penetrating structural projectile is designe tiles with mass of 0.15 and 1.5 kg and impact velocity ranging from 1 030 The projectile structural response,mass loss and critical survival velocit condition are discussed. The results show that the three failure mode of etration condition are head eroding plus parietal ablation, bending/tail ing,and the head eroding and mass loss increase with impact velocity. y d, and experiments of projec- to 1 630 m/s are carried out. for projectile in high-velocity proj ectile crushing, velocity pen- and structure crush
