Couplings that actively stabilize vibrations

A non-transitory computer readable medium embodying programmed instructions which, when executed by a processor, are operable for performing a method for damping vibration in a mechanical system, the method comprising

• detecting a vibration at a coupling of the mechanical system, by detecting changes in resistance at piezoelectric sensors disposed at the coupling;
• generating a countervibration based on the detected vibration via a flywheel disposed at the coupling, by applying pulsed magnetic forces to the flywheel;
• and
• operating the mechanical system while generating the countervibration.

An apparatus for damping vibration in a mechanical system, the apparatus comprising:

• a coupling comprising:
• vibration detection sensors at the coupling;
• vibration engines at the coupling that comprise flywheels that are eccentric;
• and
• a controller that is coupled for communication with the vibration sensors and the vibration engines, and is configured to determine a magnitude and a frequency of a vibration detected by the vibration detection sensors, and to direct the vibration engines to generate a countervibration based on the magnitude and the frequency, wherein:
• generating the countervibration comprises applying pulsed magnetic forces to at least one of the flywheels.
