Simulation test bench for LIE and HIRF on a communication bus

This paper deals with the building of a theoretical simulation test bench for LIE and HIRF on a communication bus. For that purpose, we propose a description of the methodology used to predict the induced levels on the BUS for typical scenario derived from aircraft topology. Models needed to perform such a simulation are coupler model, transformer model, cable model, injection model. To validate the simulation chain before the exploitation, we perform two kind of validations i.e. simulations / measurement comparisons: one at component level and the other one on a setup representative of aircraft. The predicting tool used in this study is Aseris NET. It solves network equations in the frequency domain with multiconductor transmission lines method.
