由于飞机用电设备电磁兼容整改过程中缺乏针对性整改措施,导致波形失真程度大。因此,文章提出基于时域有限差分法的飞机用电设备电磁兼容整改方法。引入时域有限差分法,计算电磁场干扰分量和电磁干扰隔离度,根据电磁干扰隔离度、电磁场干扰分量,选择合适材料,评估电磁兼容屏蔽场设计材料的综合性能,生成电磁兼容屏蔽场,滤波处理飞机用电设备电磁,优化线路布局和设计,实现基于时域有限差分法的飞机用电设备电磁兼容整改。实验结果证明,该方法有效控制波形失真程度在2mm内,可提高飞机用电设备的电磁兼容性能。
Rectification method of electromagnetic compatibility of aircraft electrical equipment based on finite-difference time-domain method
Due to the lack of targeted rectification measures in the rectification process of electromagnetic compatibility of aircraft electrical equipment,the waveform distortion is large.Therefore,a rectification method for electromagnetic compatibility of aircraft electrical equipment based on finite-difference time-domain method is proposed.The finite difference time domain(FDTD)method is introduced to calculate the electromagnetic interference component and the electromagnetic interference isolation degree.According to the electromagnetic interference isolation degree and the electromagnetic interference component,suitable materials are selected to evaluate the comprehensive performance of the electromagnetic compatibility shielding field design materials,generate the electromagnetic compatibility shielding field,filter the electromagnetic field of aircraft electrical equipment,and optimize the circuit layout and design.The rectification of electromagnetic compatibility of aircraft electrical equipment based on finite-difference time-domain method is realized.Experimental results show that this method can effectively control waveform distortion within 2mm and can improve the electromagnetic compatibility of aircraft electrical equipment.
