Analysis of Electric Oscillations in Explosive Magnetic Generators of Frequency

为了确定爆炸磁频率发生器的工作模式与其电参数之间的关系,该文以装置的电阻和电感的数值模拟结果为基础,建立了电阻和电感的经验数学模型,推导出了装置输出电流信号的解析形式——Bessel函数,根据Bessel函数的特性,探讨了有关电路参数的设计要求。数值模拟结果表明:当爆炸磁频率发生器的特征时间与初始角频率的乘积较大时,装置的输出信号呈振荡模式,且该乘积越大,载波频率越高,装置产生的电磁能越易于辐射。

To establish the relationship of output signals and electrical parameters of explosive magnetic generators of frequency （EMGF）, an experience mathematical model of resistance and inductance is established based on the numerical simulation results of resistance and inductance, and the analytical form of EMGF＇ s output current signals is deduced. The form is called Bessel function. According to its property, the circuit parameter design request is discussed. The simulation result shows that the output signal of the generator is the oscillation mode when the product of characteristic time and initial angular frequency is large enough. The larger the product is, the higher the carrier frequency is and it is beneficial to the radiation.
