UNCERTAIN DYNAMICAL SYSTEMS IN THE MEDIUM-FREQUENCY RANGE

This paper presents a novel probabilistic model of random uncertainties for dynamic systems in the medium-frequency (MF) range. This approach combines a nonparametric probabilistic model of random uncertainties for the reduced matrix models in structural dynamics with a reduced matrix model adapted to the MF range. The theory is presented and the random energy matrix relating to a given MF band, its random trace, and its random eigenvalues are studied. A numerical example is provided allowing convergence properties and stability of random responses with respect to the bandwidth to be analyzed.
