Abstract
The disclosure is directed at a method and apparatus for controlling unwanted vibrations in a mechanical system. The apparatus includes a set of different eccentric and/or concentric masses mounted to the mechanical system for generating forces to counteract the sensed unwanted vibrations. The apparatus further includes a set of motors that control movement of the set of masses.
Claims15
Apparatus for vibration control of unpredicted vibrations within a mechanical system comprising:
- a mounting structure to connect the apparatus for vibration control to a portion of the mechanical system;
- a set of at least two motors connected to the mounting structure, the set of motors including at least two motors co-linear with each other along a motor axis of rotation, the motor axis of rotation parallel to the portion of the mechanical system to which the mounting structure is connected;
- and
- a set of eccentric masses, the set of eccentric masses in a one-to-one relationship with the set of at least two motors;
- wherein movement of the set of eccentric masses to address the vibration control include oscillatory movement of the set of eccentric masses;
- and
- wherein the movement of the set of eccentric masses is in response to the unpredicted vibrations within the mechanical system to reduce vibrational movement and provide the vibration control.

A system for vibration control for a mechanical system comprising:
- a set of at least two motors, the set of motors co-linear with each other along a motor axis of rotation;
- a set of at least two eccentric masses, the set of at least two eccentric masses connected to each of the set of at least two motors at the motor axis of rotation;
- wherein actuation of each of the set of at least two motors causes the set of at least two eccentric masses to oscillate;
- and
- wherein the actuation of each of the set of at least two motors is in response to unpredicted vibrations experienced by the mechanical system to reduce vibrational movement and provide the vibration control.
