Modèle réduit en dynamique vibratoire basse et moyenne fréquence pour des structures mécaniques complexes

Abstract : We present the construction of a new method of reduced-model for dynamic structures in which there are global modes and local modes. The reduction technique used to separate the two types of elastic modes in first building a base of global displacements, then complemented by a base of local dis- placement. Both bases are obtained based on a correct partition of the structure obtained by the Fast Marching Method. The method is applied to a complex numerical model of vehicle.
