摘要
为了探索电磁轨道炮二阶过阻尼电路的暂态过程,分别建立了以储能电容器上的电压、放电回路电流和电枢反电动势为暂态量的数学模型。运用Matlab软件分析了不同电感梯度下三者的变化规律。分析结果表明:电感梯度增大,电压和电流波动较小,反电动势波动较大。随着时间的增加,电流和反电动势的波动幅度比较显著,达到峰值后单调的衰减到零,而电压则一直单调的衰减到零。
To explore the transient process of the second order over damping circuit in the electromagnetic railgun,mathematical models for transient quantity of the storage capacitor voltage,the discharge circuit current and the armature back electromotive force(EMF) were respectively established in this paper.Their change laws in different inductance gradients were analyzed by using Matlab software.The results showed when the inductance gradient increases,the fluctuations of voltage and the current are small,but the fluctuation of back EMF is big.With the time increase,the current and the back EMF fluctuate obviously and drably attenuate to zero after a peak,but the voltage always drably attenuates to zero.
