Abstract

Journal of Vibration and Control, Ahead of Print.
In structural dynamics of gyroscopic systems, accurately modeling system behavior using finite element methods remains challenging due to uncertainties in system matrix parameters. Traditional methods for correcting such systems often rely on matrix ...
