摘要
位于地面上一定高度的线缆束场线耦合效应研究是电磁环境效应和电磁兼容分析的重要内容。研究了不同种类线缆束的FDTD迭代公式,通过对不同公式之间异同的比较与分析,建立了适合不同线缆求解的普适性模型,大幅降低了程序设计代码上的冗余度。通过在若干算例中与全波分析软件仿真的结果进行比较,验证了模型及程序的有效性和准确性。
To study the field-to-line coupling effect of cable harness at a certain height to the ground is an important content of analyzing electromagnetic environmental effects and electromagnetic compatibility.The FDTD iterative formulas for different types of cable harness are studied.Through a comparison and analysis of the similarities and differences between different formulas,a universal model suitable for solving different cables is established,which greatly reduces the redundancy in the program design code.The validity and accuracy of the model and program are verified by comparing with the simulation results of full-wave analysis software in several examples.
