Airbus to Deploy CAESAM Multi-Disciplinary Framework for A XWB Structural Analysis

Effect of design principles? To determine transverse dimensions for minimum weight with manufacturing constraints and stress feasibility.

What is rapid structural sizing? A structure sizing process whose speed is compatible with the reactivity required in early airframe design milestones For each architecture: For such an optimisation problem we need be able to move from global geometry idealizations to very specific stress analysis idealizations, GFEM idealizations or very detailed representations that capture local detail skin ramps, stringer growouts, etcall in a single loop.

We thus easily find that Different model descriptions are required even within a single discipline field Thus, the ability to automatically map between different idealizations is key component for numerical optimisation.

Set up of a full aiirbus optimisation run is a true logistics problem. We must note however that the complexity is growing significantly requiring both a significant effort to properly setup the analysis and substantial knowledge in sizing processes for multiple components.

Laminate manufacturability measures are accounted for directly during initial pre-sizing Manufacturability measures target layup time reduction by controlling ply drops, ply continuity and volume variation. The technique has been demonstrated on A upper cover and bottom cover Manufacturability measures are an essential ingredient to constraining laminate evolution Manufacturability measures are in use for current A runs NAFEMS Optimization by Simulation 30th of May – Paris.

Ply-by-ply optimisations for A Optimisation scenarios: Sizing optimisation through large-scale simulation. Continuous approximations are tedious for small numbers of plies Optimization problems are wirbus not well-posed requiring catalogues not airbua easy to interpolate Criteria can be non-differentiable It is difficult to address mixed variable optimization with a good level of performance when large number of variables From Engopt Rio de Janeiro: Multi-level or multi-step approaches: A study of failure criteria of variable stiffness composite panels Fiber reinforced composites has been widely used in the field of Aeronautics, Astronautics.
