EMC Studies Of Cables Inside The Cabin Under Strong Electromagnetic Pulse

With electromagnetic environment becoming more complex, electromagnetic compatibility is important indicators related to the device can work properly. Meanwhile, with more and more in recent years, UAVs to serve in production and living, and will appear more in harsh environment, including the nuclear environment and lightning electromagnetic pulse surroundings. UAV equipment mainly concentrated in the cabin, and connected by a cable, so the cabin cable research is of great significance. In this paper, the establishment of UAV cabin model, simplifying the internal layout, by analyzing the port voltage, electromagnetic compatibility strong electromagnetic pulse simulation environment.In this paper, the basic concepts of electromagnetic compatibility and significance, introduces the contents of EMC research, and current research and development to make an analysis. In complying with the basic principles of electromagnetic compatibility on the basis set forth a complete EMC design process. Thereafter, the common environment of strong electromagnetic pulses on the frequency domain and time domain presentation, including high-altitude nuclear explosion lightning electromagnetic environment and electromagnetic environment, and the coupling of electromagnetic pulse were introduced.This article uses electromagnetic simulation software on the cable case of strong electromagnetic pulse environment studies, mainly related to the algorithm include Time Domain Finite Integration and Transmission Line Matrix Method. First of all finite existence over long cable-free cabin environment agency in the induced voltage terminal, including cables between itself and radiation cable mutual crosstalk of two parts. Then, on this basis, the cable model is placed in a strong electromagnetic pulse Case HEMP environment, study the coupling of the cable, and by changing the polarization direction of the electric field of the incident radiation, the incident angle of the incident wave, study different types of induced voltage cable terminal. Thereafter, the three-dimensional mapping software to map out UAV model, the difference in the first study to HEMP Case of strong electromagnetic pulse environment shielding effectiveness of different parts of the cabin, then, on this basis, the different types of cables in a different Trends arranged in the cabin, and further draw influence and change the direction of the wiring cable types within the drone of the cabin cable terminal voltage is induced by the induced voltage cable terminal to get on the cable EMC analysis and research.
