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.
Claims17
Apparatus for vibration control of 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.
1 more element
A method of vibration control for a mechanical system comprising:
- obtaining measurements associated with undesired vibrations;
- calculating a set of torque and force measurements to counteract the undesired vibrations;
- converting the set of torque and force measurements to a set of eccentric masses movement instructions values;
- and
- actuating motors according to the set of eccentric masses movement instructions values to actuate the set of eccentric motors.
2 more elements
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 rotate about the motor axis of rotation.
