| 摘 要： | 为研究材料对串联爆炸成型弹丸(EFP)形成的影响,在理论分析的基础上,提出双层药型罩形成分离EFP的判据。利用数值仿真软件AUTODYN,研究串联EFP形成的力学现象。进行双层药型罩EFP形成的实验研究,得到串联EFP形成过程的X光照片。试验结果与仿真结果比较吻合。从试验和仿真结果看出,分离EFP的形成,不仅依赖于内、外罩材料的选择,还与药型罩的结构设计密切相关。

| Abstract: | In order to study the effects of liner materials on the formation of Double-Layer Shaped Charge(DLSC) into tandem EFP(explosively formed projectile), the criterions which decide whether DLSC can form tandem EFP were proposed based on theory analysis.Utilizing two-dimensional finite element dynamic code AUTODYN, the numerical simulations on the mechanical phenomenon of DLSC forming into tandem EFP were carried out.X-ray pictures were obtained after experiments on DLSC.Comparisons between experimental results... |
