摘要: 以双腔体级联系统为实验对象,测量了系统的输出端感应电压,对实验结果进行统计分析,并与随机拓扑模型计算结果进行对比,两者基本吻合,验证了随机拓扑模型的适用性；利用该模型计算分析了不同脉冲参数及不同拓扑结构条件下多混沌腔体复杂系统的电磁耦合统计特性。研究表明,脉冲宽度和脉冲个数与概率峰值处的感应电压均存在一定的谐振特性,且脉冲频率越低,脉冲的耦合效率越高,采用串型的拓扑结构更加有利于系统的防护和加固。Abstract: With the double-cavity cascade system, the induced voltage of output port is measured. The statistical result of the experimental data matches basically with the calculated result, which verifies the practicability of the random topology model. With this model, the statistical characteristics of electromagnetic pulse coupling on the complex system with different pulse parameters, as well as different topology structures are discussed. Research shows that, both pulse widths and pulse number have some resonant characteristics with induced voltage of peak probability. And the lower pulse frequency is, the higher coupling efficiency will be. The serial topology structure is most beneficial to the protection and reinforcement of system.
