爆炸式电磁感应脉冲发生器

Explosion-driven electromagnetic induction pulse generator

为了探索脉冲发生器新的技术方法,在传统脉冲发生器的基础上,提出了一种依靠爆炸驱动的电磁感应脉冲发生器。介绍了发生器的工作过程,对发生器中炸药的爆炸和冲击过程进行了计算和数值模拟,建立了带有初始电压和初始静磁场的发生器的工作电路模型,得出了感应电压的计算方法。设计了一种通过永磁体提供初始静磁场的脉冲发生器,并分别对装有两种不同炸药的发生器进行了实验。实验表明:爆速较高的炸药驱动发生器可产生峰值更高的电压脉冲。实验结果偏低于计算结果,原因是理论计算中简化了磁芯磁场和冲击波速度。

In this work,based on the traditional pulse generators,we present an electromagnetic induction generator driven by explosion as a new technology of electromagnetic pulse generator.Having described the working process of the generator,we simulated and calculated the shock process of the explosion.Furthermore,we established the model for the working circuit of the generator with initial voltage and static magnetic,obtaining the calculation method of the induced voltage.An experimental generator with initial static magnetic provided by permanent magnet was designed,and the generators respectively fitted with two different explosives were tested.The experimental results show that the generator driven by higher detonation velocity of explosive can produce higher peak and shorter rise time voltage pulse,which are found to be a little lower than the calculation results due to the simplification in theoretical calculation of the magnetic field of the core and the velocity of shock wave.
