Abstract | An active damping system for a driveline includes a prop shaft configured to transmit engine power from an engine to a load, a sealed damper housing, and an active damping fluid contained within the sealed damper housing. A viscosity of the active damping fluid is changeable based on a torsional vibration of the prop shaft. The active damping system further includes a piston fixed to a side of the prop shaft and in communication with the active damping fluid. The piston is configured to rotate about an axis of the prop shaft. The system further includes a viscosity changing unit in communication with the active damping fluid, and a controller operatively connected to the viscosity changing unit. The controller is configured to cause the viscosity changing unit to change a viscosity of the active damping fluid. The viscosity of the active damping fluid changes the torsional vibration. |
