Abstract
International audience; This paper is devoted to the construction of a stochastic reduced-order model for dynamical structures having a high modal density in the low-frequency range, such as an automotive vehicle. This type of structure is characterized by the fact that it exhibits, in the low-frequency range, not only the classical global elastic modes but also numerous local elastic modes which cannot easily be separated from the global elastic modes. An approach has recently been proposed for constructing a reduced-order computational dynamical model adapted to the low-frequency range. First, the domain of the structure is decomposed into subdomains. Then an ...
