Abstract

Due to their interaction with end current leads during implosion, high-energy cylindrical liners driven by disk EMG currents can gain considerable longitudinal asymmetry, like, for example, in the joint RF-US experiment HEL-1 (1996), which agrees with computations using various 2D techniques. This paper using 2D DRAKON and MEDUZA computations demonstrates the possibility to cardinally improve the longitudinal compression symmetry for this liner type as compared to that in HEL-1. The influence of liner geometry and strength parameters as well as ponderomotive unit end current lead parameters on the liner compression longitudinal symmetry is studied. Data is obtained which is needed for selection of the ponderomotive unit for the second potential joint VNIIEF/LANL explosive magnetic experiment (HEL-2) in order to achieve a high longitudinal symmetry of impact of the cylindrical solid liner on the target at liner velocity up to 15 km/s.

在最强大的盘式肌电图中实现圆柱形金属衬垫高度纵向对称的可行性

由于它们在内爆期间与端电流引线相互作用，由盘状肌电电流驱动的高能圆柱形衬垫可以获得相当大的纵向不对称性，例如，在RF-US联合实验HEL-1(1996)中，它与使用各种二维技术的计算一致。本文使用二维DRAKON和MEDUZA计算表明，与hel1相比，这种衬垫类型有可能从根本上改善纵向压缩对称性。研究了线型几何参数和强度参数以及机车单元端电流引线参数对线型压缩纵向对称性的影响。获得了第二次VNIIEF/LANL炸药磁力联合实验(hel2)的有源单元选择所需的数据，以实现圆柱形固体衬里在衬里速度高达15 km/s时对目标的高度纵向对称冲击。
