Application of Computational Electromagnetic in EMC Simulation

由于航空飞行器上用电设备电磁兼容问题频发及其复杂性,用电设备的电磁兼容设计就显得尤为重要。为此,提出了利用计算电磁学理论对用电设备的电磁兼容性进行分析,针对系统中不同电磁兼容问题以及不同数值计算方法的自身特点,选择适用的数值方法对问题进行仿真计算。最终实现在产品的设计初期,就能够对其电磁兼容性进行预测和评估,满足其电磁兼容性的要求。因此,采用计算电磁学进行仿真分析可为解决用电设备电磁兼容问题提供有效的手段和途径。

The electromagnetic compatibility （EMC） problem of aircraft electric equipment is complex and happened fre- quently, the electromagnetic compatibility design of electric equipment is particularly important. A technique that using com- putational electromagnetic theory to solve problem of EMC is presented. According to the system of electromagnetic compati- bility issues and its own characteristics of different numerical methods, the applicable methods are selected to solve the different problems. Finally, prediction and assessment can be realized in the stage of production design, and the EMC require- ment of electric equipment can be fulfilled. So, the computational electromagnetic provides effective means and channels to solve the problems of aircraft EMC.
