| 摘 要： | 针对混凝土的脆性特点,设计了有预先破坏功能的异形头部弹体,进行了侵彻混凝土实验. 利用高速摄影仪记录了隧道区初始阶段的速度,通过比较隧道区的平均侵彻阻力,分析了异形头部弹体和卵形弹体的侵彻阻力. 基于Forrestal公式分析了卵形弹体静态侵彻阻力与异形头部弹体的差别. 实验和计算结果表明,异形头部弹体能有效减小侵彻阻力.

| Abstract: | To reducing penetration resistance and increasing the depth of penetration, two types of nose headed penetrator (NHP) were proposed based on the characteristics of concrete. Penetration experiments were proceeded to analyse the feasibility of NHP's reducing resistance and the influence of NHP on penetration resistance. The penetration depths and resistances of NHP and ogive-nose penetrator were computed and compared based on the Forrestal formula. The experimental and computational results show NHPs can reduce the penetration resistance, NHPs can increase the depth of penetrators by 10% after optimizing. |
