  • Active vibration cancellation of gear mesh vibration
    Patent number: 6865466
    Abstract: A drivetrain component assembly comprising a drivetrain structure, means for generating a reference signal indicative of a frequency with which the drivetrain structure vibrates during operation of the drivetrain structure, at least one actuator coupled to the drivetrain structure, at least one sensor operable for monitoring vibrations transmitted from the drivetrain structure and producing a sensor signal in response thereto and a controller coupled to the at least one actuator and the at least one sensor. The controller receives the sensor and reference signals and generates an actuator signal in response thereto. The at least one actuator receives the actuator signal and generates a canceling vibration in the drivetrain structure in response thereto. The canceling vibration has a predetermined frequency and amplitude to substantially cancel-out vibrations in a predetermined bandwidth that are generated during the operation of the drivetrain structure.
