RÉSUMÉ

. Les méthodes de modification structurales s’attachent à prédire l’effet de l’ajout de masse, de raideur ou d’amortissement sur une structure qu’on ne connaît que de manière expérimentale. Le présent article décrit la validation expérimentale de la méthode pour des modifications structurales dissipatives sur un démonstrateur semi-industriel.

ABSTRACT

. The structural dynamic modification methods are used to predict the effect of adding mass, stiffness or damping on an only-experimentally-known structure. This article presents the experimental validation of the method for a dissipative modification on a mock- up example.

MOTS-CLÉS

: modification structurale, analyse modale expérimentale, couplage hybride, viscoélasticité .

KEYWORDS

: Structural Dynamic Modification (SDM), experimental modal analysis, hybrid coupling, viscoelasticity.
