    摘要： A shaft structure and at least two insert members. The shaft structure has a longitudinally extending cavity and is configured to vibrate in response to the receipt of an input of a predetermined frequency such that at least two second bending mode anti-nodes are generated in spaced relation to one another along the longitudinal axis of the shaft structure. The insert members are disposed within the longitudinally extending cavity and engage an inner wall of the shaft structure. Each of the insert members is located at a position that approximately corresponds to an associated one of the anti-nodes and has a density that is tailored to an anticipated displacement of the associated anti-node. A method for attenuating noise transmission from a vehicle driveline is also disclosed.

    摘要： 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. A method for analyzing the effect of a drivetrain component on a level of noise, vibration and harshness transmitted to a vehicle passenger compartment is also provided.

    摘要： A vibration damper includes a hub, a first mass, a first resilient coupling, a second mass, and a second resilient coupling. The first mass is disposed concentrically about the hub. The first resilient coupling resiliently couples the first mass to the hub. The first resilient coupling has a first spring constant. The second mass is disposed concentrically about the first mass. The second resilient coupling resiliently couples the second mass directly to the first mass. The second resilient coupling has a second spring constant that is less than the first spring constant. The first mass and the first resilient coupling are configured to attenuate vibration at a first frequency. The second mass and the second resilient coupling are configured to attenuate vibration at a second frequency. The second frequency is lower than the first frequency.
