摘　　要：闪电与飞机相互作用,在机载电缆束上产生电压和电流,这些电压和电流可能会导致关键电子设备损坏或出现故障,因此危害飞行安全。随着飞机材料和机载关键电子电气设备的不断改进和提高,航空工业界越来越关注飞机的闪电电磁环境对机载设备及飞机系统的影响。EMA3D可全面分析飞机遭遇闪电袭击后,其内外部电磁场分布情况,估算闪电对飞机里的线缆系统的间接效应。主要论述某机载设备的闪电电磁环境和EMA3D电磁仿真软件的功能,最后应用此软件分析飞机某机载设备周围的电场和磁场以及其连接线缆上的感应电流。Lightning interaction with aircraft, induced voltage and current on cable harness, the voltage and current may cause key electronic equipment damage or malfunction so that impact on flight safety. As the constant improvement and enhancement of material of aircraft and development of airborne key electrical and electronic equipment, how lightning electromagnetic environment influence airborne equipment and aircraft system is more and more attracted aerospace industry’s attention. EMA3D could overall analyses aircraft internal and external electromagnetic field distribution after the encounter a lightning strike and estimates lightning indirect effect on the cable system. An airborne equipment lightning electromagnetic environment and EMA3D electromagnetic simulation software function were mainly described. Electric and magnetic field around the airborne equipment and the induced current on the connecting cable were analyzed by applying EMA3D.
