Discussions about Automotive Application of the "Equivalent Cable Bundle Method" in the High Frequency Domain

This paper presents some discussions concerning the application of the "Equivalent Cable Bundle Method" on real automotive cable-networks in the high frequency domain. The principle of this modelling method, dedicated for helping system EM immunity assessment, is to reduce the complexity of point-to-point cable-links by grouping together the conductors according to their terminal loads and introduce those models in 3D computer solvers. This paper studies how some assumptions, made on geometry cross-sections of conductors or ways to group conductors, could be introduced in the rigorous method in order to simplify the application of the method in the industrial context of representative automotive cable-networks.
