Simulation of LF radiated EME of cabin

摘要

Main interference sources for electro-magnetic sensitive system in submarine platform are usually LF (low-frequency) electromagnetic radiator like high-power cable or cabinet in cabin. The characteristic and problem of radiated EME (electromagnetic environment) from cable and cabinet was analyzed, and a hybrid simulation method of EME from cable based on MoM (method of moments) and MTL (methods of transmission line) was given out. Then, the simulation models of cabin with cable or with cabinet were developed in the systemlevel EMC computation software EMC Studio. Furthermore, the distribution of EME affected by the cabin wall structure was presented. And so as to show the distributed features of the magnetic and electric field, the simulated results were given out. The obtained results and methods adopted in this paper can also be implanted in the interference effect analysis of sensitive system from cable or cabinet.
