采用电磁仿真软件FEKO对大型运输机的主要舱室及内部线缆进行了HIRF（高强度辐射场）耦合的数值仿真。通过矩量法、多层快速多极子法、物理光学法、几何光学法等算法，仿真计算了100MHz~18GHz频段HIRF辐照下，舱室内的电磁场分布，以及10kHz~400MHz的HIRF辐照下，飞机内部的电缆终端的感应电压和电流；分析了飞机舱室的屏蔽效能及不同线型的线缆的耦合规律。得出了一些有价值的结论，为飞机中电子设备的HIRF防护提供了理论依据。

In this paper, the electromagnetic simulation software FEKO is used to analyze the HIRF (High Intensity Radiated Field) coupling of the transport aircraft. By using the numerical algorithms such as MoM, MLFMM and PO, etc., the electromagnetic fields in the major cabins exposed to the 100MHz~18GHz HIRF are simulated, and the induced current in the cables in the cabins exposed to the 10kHz~400MHz HIRF are calculated. The shielding effectiveness of the cabins and the coupling rules of diverse cables are analyzed to draw some valuable conclusions, which could provide references for the HIRF protection of the equipments in the aircrafts.
