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.

摘要： Hub-mounted active vibration control (HAVC) devices, systems, and related methods are provided. An HAVC device (100) includes a housing (206) having a tolerance ring (600) attached to a rotary hub (702). The tolerance ring can accommodate dissimilar coefficients of thermal expansion between dissimilar metals. The HAVC device can also include a plurality of coaxial ring motors (308A, 308B, 310A, 310B) configured to rotate a plurality of imbalance masses for controlling vibration. An HAVC system can further include a de-icing distributor (208) for communicating instructions to one or more heating sources (HS) provided at one or more rotary blades (802) of a vehicle or aircraft. A method of controlling vibratory loads occurring at a moving platform can include providing a moving platform, mounting a vibration control device to a portion of the moving platform, and rotating at least one pair of imbalance masses such that the combined forces of the masses substantially cancel unwanted vibration of the platform.

摘要： Systems, devices, and methods for a hub-based active vibration control (AVC) design includes at least one pair of co-rotating motorized imbalanced rotors that create a controllable rotating force vector that can be controlled to cancel hub loads on a rotating hub. This control is achievable using a configuration in which each rotor has an axis of rotation that is offset from the hub axis of rotation. In this way, in a loss of operation failure mode, the system is designed such that centrifugal forces will cause the masses to spin to an orientation of low static imbalance.

摘要： Systems and methods for measuring twist on a shaft of a rotating drive system include a first set of targets circumferentially distributed around the shaft at a first axial location to rotate with the shaft and a second set of targets circumferentially distributed around the shaft at a second axial location to rotate with the shaft. The first and second sets of targets are interleaved. The system includes a sensor assembly including one or more sensors mounted around the shaft and configured to detect the first and second sets of targets as the shaft rotates. The system includes a sensor processing unit for receiving an electrical waveform from the sensor assembly, determining, based on the electrical waveform, a twist measurement of twist motion between the first axial location and the second axial location on the shaft, and determining, based on the electrical waveform, a second measurement of shaft motion.

摘要： Systems, methods, and computer program products for directional force weighting of an active vibration control system involve arranging a plurality of force generators in an array, identifying individual component forces corresponding to force outputs of each of the plurality of force generators, determining a combination of the individual component forces that will produce a desired total force vector, and adjusting the outputs of each of the plurality of force generators such that the combination of the individual component forces are at least substantially similar to the desired force vector.

摘要： A non-contacting torquemeter capable of measuring torque in a rotating shaft with improved accuracy in the presence of relative motion between a rotating shaft and a transducer assembly is provided. The non-contacting torquemeter has improved robustness and reliability, and is able to self-calibrate. The non-contacting torquemeter is able to provide accurate torque measurements using a single transducer assembly positioned at a single azimuthal position on a rotating shaft.
