CST闪电间接效应研究

CST Study on Lightning Indirect Effect

摘要: 闪电通过飞机开口缝隙耦合进入飞机内部，产生电磁干扰。本文利用CST仿真软件在787模型上设置开口缝隙结构，对其电磁耦合机理进行验证；选取了不同型号的传输线，对比分析其电磁屏蔽性能，为线缆铺设改装提供依据。

Abstract: Lightning is coupled into the airplane through the gap of the aircraft, which produces electromagnetic interference. In this paper, the CST simulation software is used to set up the slot structure on the 787 model to verify its electromagnetic coupling mechanism; this simulation selects different kinds of cables, analyzing their electromagnetic shielding performance by comparison and providing the basis for the cable laying and modification.
