| 摘 要： | 采用ANSYS/LSDYNA有限元软件数值模拟研究了药型罩参数对周向MEFP成型的影响.通过对成型后的集群EFP性能统计分析,得到药型罩曲率半径、壁厚和口径对周向MEFP成型性能的影响规律和参数之间的合理匹配关系.结果表明,在爆炸载荷作用下,周向MEFP装药形成的中间层EFP速度明显大于边缘上下层EFP速度；而且当药型...

| Abstract: | Numerical simulations by a ANSYS/LS-DYNA finite element software were carried out to research the influence of the parameters of liner on the forming of circumferential MEFP.By statistic analysis of the formed assembly EFP,the regulation of the curvature radius,thickness and caliber of the liner′s influence to the forming of circumferential MEFP and the appropriate relatives among parameters were obtained.The result shows that the speed of the middle EFP formed by the circumferential MEFP is apparently larger than the marginal EFP under explosive loading.While the ratio of the curvature radius and the caliber of the liner vary from 0.9
