摘　　要：针对高压脉冲电源供电的被动电磁装甲系统重要结构参数——装甲板间距进行了优化分析。对与装甲板间距有关的电流对金属射流的完全作用时间、作用时间、装甲板电感,以装甲板间距为寻优变量,采取离差标准化方法,建立了带有权重系数的目标函数。利用Matlab仿真分析了权重系数对目标函数的影响,结果表明,为使目标函数取得较小值,应增大完全作用时间和作用时间的权重c1、c2,而减小装甲板电感的权重c3,且c1>c2,c1≥0.6,c2≥0.2,c3≤0.2。当这3个权重取0.7、0.2、0.1时,最优板间距约为65 mm。The armor plate spacing was optimized, which was an important structure parameter in passive electromagnetic armor that high voltage pulse power supplied energy. For the complete action time and the action time of current on the metal jet, and armor plate inductance, which associated with armor plate spacing, the objective function was established based on the dispersion standardization method in which armor plate spacing was taken as optimization variables. The ef- fects of weight coefficients on objective function were analyzed by Matlab. The results showed that in order to make the ob- ject function to get a smaller value, weight coefficient with complete action time and action time should be increase, weight coefficient with armor plate inductance should be decrease, and c1 〉 c2, c1≥ 0.6, c2 ≤0.2, c3≤ 0.2. When the three weight coefficients were 0.7, 0.2, 0.1, the optimal plate spacing was about 65 mm.
