Positioning of FDX in V-Model

Details

FDX ist a format for data exchange of functional (measured or simulated) data (characteristic value/ curve/diagram) for mechanical parts, modules, assemblies between OEM and suppliers. The FDX Format is based on the ASAM ODS standard and on the OpenMDM framework. It supports relevant processes at OEMs and suppliers with respect to the order and delivery processes for functional data for mechanical components. FDX is a generic format but has specific shapings for different component groups (e.g. bushings, dampers).

Relevance and Benefit for MBSE

System Engineering relies heavily on functional models of mechanical components and systems. These functional models of mechanical components require input data as parameter sets. The FDX-Format aims to standardize and establish an exchange format for this functional data.

Major Reasons from Industry:

Harmonizing variety of different data exchange formats (non standards) for functional data of mechanical components and systems
Improve efficiency through increased process automation with OEM and suppliers
Achieve consistency between data requirements and data delivered
Support cooperation OEM/Supplier

Risks and Impediments

Slow take off of implementation of VDA/prostep ivip recommendation
Efficient cross company/ cross domain data exchange of functional data cannot be achieved
