This paper describes a methodology for modeling of EM coupling on an aircraft Electrical Wiring Interconnection System (EWIS). The challenge is to be able to generate an operatory model taking into account the large number of cables and to maintain a reasonable computation time for the evaluation of the distribution of currents at the interface of equipment pieces. For this, a geometrical condensation...
This paper presents a comprehensive application of the Field-to-TL approach implemented through a computer framework designed to facilitate data exchange among different computational tools. The framework is used also to compare results from different codes, specifically MDD (Multilevel Domain Differentiate) and CRIPTE, thus providing a validation test case for both of them. Furthermore, the comparison...
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...
This paper describes the procedure put to the fore in the EC's FP7 HIRF-SE project for carrying out HIRF simulations at aircraft level. The solution proposed is based on the use of MTLN models cable links under test and a 3D full wave solver including thin wire models in order to take into account coupling with the whole structure and the rest of the wiring. Further simplifications based on the cable...
This paper proposes an original numerical strategy in order to assess high frequency coupling in large systems, typically for HIRF applications, in a frequency range in which classical full waves numerical schemes such as FDTD or MoM become tedious and sometimes inappropriate to use. This strategy is based on a logical topological decomposition of the electromagnetic (EM) problem as sub elementary...
This paper describes the approach developed in the HIRF-SE EU FP7 project in order to model the topology of a complex aeronautic harness, provided by Piaggio Aero Industries. This approach is based on the CRIPTE modeling software (for Multiconductor Transmission Line Network analysis). To validate the correctness of the model of the topology of the complex harness, S-parameter measurements have been...
This article describes an approach developed in the HIRF-SE EU FP7 project in order to model the conducted disturbances at the equipment interface due to Back-Door constraints. This approach is based on the “association” of two modeling tools: CRIPTE for Multi conductor Transmission Line Network resolution, and IMEA for equipment input impedance modeling. Both tools are here demonstrated for the analysis...
