Méthodologie pour génération de modèles réduits dynamiques multiphysiques : application aux open rotors

Abstract : The mechanical design of a system involves many investigations, notably the validation of its structural behaviour over its operating frequency range. This kind of analysis can be numerically performed using the finite element method, however in such a context, the required accuracy and detail level imply models whose significant sizes lead to time consuming simulations. Moreover, the optimization process of such a system may request numerous validation computations that turn out extremely slow the design process. In the framework of this PhD we target a reduction methodology whose main features are: being compact, dealing with non-linear displacement and recovering the damping effects of the model joint due to the contact-friction phenomenon.
