摘要
针对缝隙结构建模在计算精度与求解时间之间的矛盾,提出了一种基于转移阻抗的复杂缝隙等效建模方法,采用传输线矩阵法对大型方舱复杂缝隙结构的电磁耦合特性进行了仿真研究。仿真结果表明,该方法可大幅减少网格数量,有效缓解仿真精度和计算时间之间的矛盾。
To solve the contradiction between the computational accuracy and efficiency on apertures analysis, an equivalent modeling method is proposed based on the theory of transfer impedance. The electromagnetic coupling effects of complex apertures for the large shelter are analyzed by applying the transmission line matrix（TLM） method. The numerical simulation indicates that the number of mesh can be significantly decreased by using the equivalent method. Also, the conflict between the calculation accuracy and the computational time can be effectively mitigated.
