摘要

摘要: 为了研究曲率半径对串联爆炸成型弹丸（EFP）形成的影响，利用有限元软件 AUTODYN，对双层球缺罩串联EFP的成型过程进行了数值仿真，在此基础上分析了双层球缺罩串联EFP的形成机理，探讨了曲率半径对串联EFP的影响规律。开展了双层药型罩EFP形成的实验研究，得到了串联EFP形成过程的X光照片，仿真和试验结果比较一致。仿真与试验结果都表明：双层球缺罩可以形成前后分离的串联EFP，双层球缺罩的曲率半径对串联EFP的速度、外形和长径比有较大影响。

Abstract: In order to study the influences of liner curvature radius on the formation of double layer shaped charge liner (DLSCL) into tandem explosively formed projectile (EFP), the numerical simulations on the mechanical phenomenon of DLSCL forming into tandem EFP were carried out by using two-dimensional finite element dynamic code AUTODYN. The formation mechanisms of DLSCL and the influence of curvature radius on the formation of DLSCL were studied. After tests on the formation of DLSCL were performed, the X-ray pictures were obtained. Comparisons between experimental results and numerical simulation results show a good agreement. It can be concluded from the results that DLSCL can form tandem EFP and the liner curvature radius has great influence on the velocity, shape and l/D radius of tandem EFP.
