| 摘 要： | 固体套筒内爆是采用实验方法研究高能量密度状态下的材料力学性能的重要加载手段之一，国内已经建立起若干开展电磁内爆研究的驱动器。从电流脉冲前沿对固体套筒内爆性能影响的角度进行分析，为如何选择现有的实验装置开展固体套筒内爆实验研究提供依据。采用不可压缩零维模型进行计算，获得了套筒内爆速度受套筒尺寸、电流幅值以及电流脉冲前沿的影响情况。计算结果表明，开展固体套筒内爆的实验研究应选择电流脉冲前沿大于2 s的装置，这也为未来设计驱动能力更强的固体套筒内爆实验装置奠定了基础。

| Abstract: | The electromagnetic driven solid liner implosion is one of the high energy density (HEDP) experimental techniques. Some drivers have been constructed in the past years, these drivers are varied in peak current and current rise time. This paper analyzes the effect of current rise time on the solid liner implosion, in order to provide some advice on the choice of the existed drivers which will be appropriate for solid liner implosion experiment. Calculations were performed under uncompressible zero dimension model, the effects of liner size, current amplitude and current rise time on implosion velocity were obtained. The results indicate that drivers with current rise time above 2 microsecond would be appropriate for solid liner implosion experiment. The analysis also lays the theoretical foundation for the future design of high capacity drivers used for solid liner implosion experiment. |
