摘要
研究螺旋型爆磁压缩发生器的损耗机理,建立了一种磁通损耗项和电阻损耗项解耦表示的爆磁压缩发生器运行模型,并给出了物理意义明确的损耗项解析式;经实验验证,对于损耗机理更为复杂的紧凑型级联爆磁压缩发生器,本模型仿真结果与实验结果仍符合良好,仿真波形与实验波形总体趋势一致,螺距变化的节点处过度清晰,定子均绕段的波形相似度较高.
A decoupling operation model has been developed for the helical magnetic flux compression generator.The model reveals the mechanism of losses with analytical expressions and clearly physical implication.Based on the proposed model,the experiment and simulation were implemented for the compact cascading magnetic flux compression generator with more complex losses mechanism.The results show that experimental results are in compliance well with the simulation results of the model.The current waveforms of experiment and simulation vary in the same trend,in which the change of transition is clear at the pitch points of stator.At the smooth segment of stator,the consistency of experimental waveforms with simulation ones is even better.
