HUB-BASED ACTIVE VIBRATION CONTROL SYSTEMS, DEVICES, AND METHODS WITH OFFSET IMBALANCED ROTORS

摘要

Systems, devices, and methods for a hub-based active vibration control (AVC) design are of co-rotating electric unbalanced rotors that create a controllable torque vector that can be controlled to cancel hub loads on a rotating hub. It contains more than one pair. This control is achievable using a configuration in which each rotor has an axis of rotation offset from the axis of rotation of the hub. In this way, at the loss of the operational failure mode, the system is designed such that centrifugal forces cause the mass to spin in an orientation of low static imbalance.
