摘要
以俄罗斯S 300Z pinch装置的负载电流波形为基准,利用Z箍缩的质点模型对钨丝阵负载的初始半径和线质量进行了系统的优化计算,得到了不同电流幅值的电流波形所对应的优化丝阵负载参数。发现了负载最大内爆动能与负载电流幅值的平方成正比关系。电流上升时间对最优丝阵负载参数的影响的计算表明,随着负载电流上升时间的增大,负载的最优线质量也要增大。
Based on the load current of S-300 machine, in Russia, optimal combinations of radius and mass per unit length of tungsten wire-arrays were obtained by a lot of optimal calculation by means of 0-D model, under different drive current with peak value of 2.5MA, 4MA, 5MA, 6MA, 8MA, and 20MA, respectively. The calculation shows that the optimal linear mass increases with the rising time of current, and that the maximal kinetic energy of implosion is in direct proportion to square of current peak value.
