Abstract
Circular force generator (CFG) devices, systems, and methods are disclosed having indirectly driven imbalanced rotors for generating vibrations and/or imparting vibration control. A CFG device (10) includes a first set of imbalanced rotors (12) disposed about a center point and a second set of imbalanced rotors (12) disposed about the center point. The first set of imbalanced rotors is configured to co-rotate synchronously. The second set of imbalanced rotors is configured to co-rotate synchronously. The first and second sets of imbalanced rotors are configured to create a controllable rotating force vector having a controllable magnitude and phase about the center point. A CFG system includes a controller and one or more CFG devices configured to receive control commands from the controller. A method of generating a force via a CFG device includes receiving a force command and generating a force in response to receiving the force command.
