| 摘 要： | 运用LS-DYNA模拟软件研究了药型罩材料对聚能杆式侵彻体(JPC)成型的影响.通过对铝、铁、铜、钽、钨JPC的统计分析,得出材料密度和延伸率对JPC头部速度、长径比等参数的影响规律.结果表明,随着从铝到钨材料密度以及延伸率的减小,JPC头部速度降低69%,长径比降低75%, 鉴于JPC的这两个参数,铜、钽是作为JPC成型的较好材料,而铜最佳,铝易断裂、易气化,铁和钨不能够得到充分拉伸,均不适合JPC的成型.对铜药型罩进行了试验验证,试验结果与模拟结果较吻合.

| Abstract: | The influence of liner material on Jetting Projectile Charge(JPC) formation is researched by LS-DYNA software.Through analyzing and disposing,the formation shape and parameters of JPC formed by five liner materials:aluminum,iron,copper,tantalum and tungsten and the law that the formation parameters of JPC,like velocity and length-diameter ratio,influenced by the density and tensility of liner material are obtained.The result shows that following the reduce of density and tensility of liner material which is... |
