中文摘要：
分析了磁驱动飞片实验和数值计算的研究现状。根据磁驱动实验装置等效电路建立了可带入参数为表达式的电路计算程序。利用建立好的电路计算程序结合LS-DYNA980MHD计算软件,建立了一种可以耦合电路分析的磁驱动飞片计算方法。采用这种方法模拟了CQ-4的发射飞片实验,计算结果与实验基本符合。最后分析了极板长度h分别为20、25、30mm并且充电电压73kV时磁驱动飞片的速度和平面性,认为实验中极板长度取25mm比较合适。
英文摘要：
A calculation procedure of equivalent electrical circuit was programmed. Combining circuit calculation program with LS-DYNA980 MHD, a method for magnetically driven flyer simulation coupled with electrical circuit was proposed to simulate a real experimental process. The calculation result coupled with electrical circuit can be obtained. Then the CQ-4 experiment was simulated by using this method, the results of simulation agree well with the experimental results. Optimization of strip line length h = 25 mm is achieved by comparing flatness and velocity of flyer plates under different strip line length h=20, 25, 30 mm conditions when the charge voltage is 73 kV.
