针对目前国内外较少研究电磁脉冲在供电线缆、通讯线缆和数据线缆等构成的各种传输网络及其重要电子终端设备中的传导耦合规律、效应评估的现状,以典型人体-金属模型（BMM）静电放电（ESD）电磁脉冲（EMP）作为注入源,对静电放电电磁脉冲在线缆网络中的传导耦合规律进行了仿真和实验研究。建立了树形结构和环形结构线缆网络的电磁拓扑仿真模型,并运用电磁拓扑理论中的BLT超矩阵方程,采用将网络传递函数和时域卷积相结合的计算方法,得到了各结点瞬态响应的仿真结果。搭建了静电放电电磁脉冲实验平台,对理论建模仿真结果进行了实验验证,实验结果与仿真结果具有较高的一致性,从而验证了理论方法的有效性。研究结果表明,线缆网络中某一端口的脉冲响应不仅与网络结构有关,而且受到网络中线缆长度、负载阻抗等变化的影响。

Line network is the main coupling path of electromagnetic pulse energy, such as power line and communication line. Taking the typical body-metal-model (BMM) electrostatic discharge (ESD) electromagnetic pulse as the injected source, we researched the coupling principles of ESD EMP on line network I . Moreover, we established an electromagnetic topology simulation model of tree and annular networks, BLT super-matrices equation of the line networks in electromagnetic topological theory. Furthermore, a calculation method combining the transfer function of network with convolution in time are used to gain the transient responses of nodes. The method is verified by experiments, of which the results agree with the simulation results. The simulation analysis shows that the transient response is affected not only by the network structure, but also by line length and network load impedance, etc.
