摘　　要：在调研和借鉴国内外相关文献资料的基础上,文中提出一种带小圆柱体头形的新型头形弹体结构,并通过火炮试验对不同头形参数的新型头形弹体在不同侵彻速度条件下对两种靶体强度(9MPa和28.4MPa)的混凝土靶的侵彻性能开展研究,探索新型头形弹体的侵彻机理,初步建立了理论分析模型,并对比了理论分析结果和试验数据,研究表明,新型头形弹体在一定头形结构参数条件下的侵彻性能优于常规卵形头形弹体。Based on investigation of work about penetration into concrete targets at home and abroad, a cylindrical-nose- tip projeetile（CNTP） is brought forward by rebuilding ogive-nose projectile. Penetration of projectiles of different nose parameters penetrating into 9MPa and 28.4MPa concrete targets with dif[erent velocities are conducted, and then penetration mechanism and theoretical penetration model of CNTP are primarily investigated and build. Analytical results are compared with the experimental data, which shows that penetrations of the CNTP with special cylindrical-nose-tip are prior to ogive-nose projectile.
