Approche par modes de flux de puissance pour la conception robuste d'interfaces de structures

A procedure based on a power flow mode theory is presented to optimize the power flow dissipated at the junctions between substructures. These modes are derived from an eigenproblem associated to the minimization of an energy operator requiring the computation of the dynamic flexibility matrix, which remains prohibitive in a robust design context. A genetic algorithm is thus coupled to an approximate reanalysis method to determine junction parameter values which are both optimal and robust with regard to uncertainties.
