摘要
为了了解理想刚性弹丸的高速/超高速动能侵彻中弹体头部形状对侵彻能力的影响,在空腔膨胀理论基础上,基于双卵形异型头部设计,分析了头部形状系数与双卵形特征参数的依赖关系,得到了不同异型头部弹体对侵彻性能的影响规律,提出了具有较小侵彻阻力的异型头部侵彻体设计方案。与不同头部侵彻实验结果对比表明,本文的分析方法合理可行,可为高速侵彻体头部形状设计提供参考。
Nose shape of projectiles is an important factor influencing the penetration ability.For high speed/ultra high speed kinetic energy penetration of ideal rigid projectiles,this factor is becoming more serious.Based on the classical cavity expansion theory and designing scheme of double-ogival nose,this paper analyses the relationship between nose shape factor and the characteristic parameters of double ogive,and obtains the influence of modified nose projectiles on the penetration performance.It puts forward the design scheme of modified nose penetration body with smaller penetration resistance.The comparison among the results of nose penetration test,proves that this analysis and method are reasonable and feasible,and can be used in judgement for the design of high speed penetrator nose shape.
