HUB-MOUNTED ACTIVE VIBRATION CONTROL (HAVC) DEVICES, SYSTEMS, AND METHODS

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.

1. A hub-mounted active vibration control (HAVC) device, comprising:
a housing configured to attach to a rotary hub and rotate therewith, wherein the housing includes a tolerance ring configured to accommodate dissimilar coefficients of thermal expansion between components of dissimilar metals; a plurality of coaxial ring motors configured to rotate a plurality of imbalance masses; and an electrical module for independently controlling a rotational position, phase, and/or speed of the plurality of imbalance masses such that the combined forces of the imbalance masses substantially cancel unwanted vibration.
