The conceptual design is a crucial phase for the System Architects to evaluate 3D architecture concepts of mechatronic systems mainly with regard to the ElectroMagnetic Compatibility (EMC). Our research work deals with the combination of electromagnetic modeling and a topological approach to support the qualitative and quantitative ElectroMagnetic Interferences (EMI) evaluation process within the MBSE SAMOS approach as of the conceptual design. For a given interference, the analysis of topological models allows the qualitative identification of the existence of victims with their associated potential aggressors, based on the electrical schema of interacting components. Then, once the potential EMIs have been qualitatively identified, a quantitative evaluation can be performed based on the predefined electromagnetic and geometrical requirements, and on the analysis of the identified physical coupling law. Finally, this approach has been applied to the alien crosstalk occurring in an electrical vehicle powertrain, with a quantitative evaluation based on the two following methods: an analytical approach and Kron's approach.

“…According to Figure 1 these classes are: spherical, planar, cylindrical, helical, revolute, prismatic, and complex. For each class, it is possible to associate the Minimal Reference Geometric Element (MRGE) that is the minimal combination of the following simpler geometric objects, named Reduced Geometric Element (RGE): point, line and plane [12].…”

Modern engineering systems are getting complex and integrate multi-physical objects. The Model-Based System Engineering (MBSE) seems to be the best way to manage complex system design and the Systems Modeling Language (SysML) may be considered one of the computer languages to perform the designing of a complex system. MBSE also seems to be a valid solution to integrate tolerance specification into design process. In particular, in the present work SysML is used to create a set of libraries containing simple and complex volumes, primary datum and tolerance zones, according to ASME Y14.5M and ISO 1101 standards. The generation of these libraries is based on the Technologically and Topologically Related Surfaces (TTRS) model and uses the set of thirteen positioning constraints able to represent every condition between assembly features. The paper summarizes the characteristics of the created SysML objects, able to represent Datum, Datum Reference Frame (DRF) and tolerance zones. In particular, the Datum included in ASME Y14.5-M are modelled. Then, all the tolerance zones included in both standards are modelled. Finally, a three-step procedure is summarized to preliminary illustrate the way of use the developed set of SysML objects

“…As we are in conceptual design, the geometry definition of component requires to be simplified. After having studied numerous available methods to manage geometrical data [16], the most appropriate geometry modeling that we chose is the Technologically and Topologically Related Surfaces (TTRS) approach [17]. Indeed, the management of surfaces is really important, be it for the 3D representation of the system components, or for the multi-physics behaviors that are usually modeled by surface-flows.…”

“…To position TTRS relatively to each other, a constraint can be added between two TTRSs among the 13 predefined constraints. This geometrical SysML extension has already been developed and detailed in our previous work [16].…”

The conceptual design is a decisive phase where the simulation teams would like to quickly pre-validate spatial architectures from the physical architecture proposed by the system architects. In order to support them to efficiently achieve this task while meeting various industrial requirements, three approaches were proposed and compared, and finally the last and innovative approach called SAMOS (Spatial Architecture based on Multi-physics and Organization of Systems) is presented and described. The corresponding platform will allow to validate the spatial allocation of components under geometrical and multi-physical constraints, while facilitating the collaboration between the different design actors during the conceptual design.
