“春雷号”有界波EMP模拟器暂态过程的计算

Transient computation for “Spring-Thunder” bounded-wave EMP simulator

对“春雷号”有界波 EMP模拟器主开关动作前后的暂态过程建立了相应的等效电路及微分方程 ,用定步长龙格 -库塔法进行了数值求解 ,并与实测波形进行了比较 ,提出了改善输出波形的几种方法。这对于模拟器的设计、调整及改进都有一定的意义。

In this paper, the equivalent circuits and differential equations are given before and after the main switch of the EMP simulator is closed, the numerical solutions were solved by Rukkey Kuta method , which agrees with the measured waveform. Some methods have been put forward to improve the output waveform.The transient computation is important for the design, adjustment and improvementof EMP simulator.
