Equivalent cable-bundle model for large cable response in complex vehicle environment

This paper describes a simplification approach based on equivalent cable-bundle models for calculating conducted back-door disturbances at vehicle level. The challenge is to be able to generate a model taking into account a huge number of wires organized in functional bundles and to maintain a reasonable computation time for prediction of the distribution of common mode currents at the interface of equipment pieces. This approach is tested on two representative test cases at system level and aircraft level.
