Abstract
Methods and apparatus are provided for attenuating torsional vibration of a steering system. The apparatus can include a housing including a chamber. The housing can be couplable to a rim of a hand wheel of the steering system. The apparatus can include a mass disposed in the chamber of the housing. The mass can have a fixed stiffness. The apparatus can also include a damping fluid disposed in the chamber of the housing. The damping fluid can have a variable stiffness. The apparatus can include a control module that determines a torsional vibration experienced by the steering system and outputs a signal to vary the stiffness of the damping fluid in response to the torsional vibration in substantially real-time.
