CIRCULAR FORCE GENERATOR (CFG) DEVICES, SYSTEMS, AND METHODS HAVING INDIRECTLY DRIVEN IMBALANCED ROTORS

摘要

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.
