Abstract:
An apparatus and method for damping vibration of a vehicle part, such as a steering wheel or an electric motor, is provided. According to one embodiment, an apparatus (26) for damping vibration of a vehicle part (12) includes at least one container (50) having a chamber (56) defined by at least one interior wall (58). The container (50) is associated with the vehicle part (12). A plurality of particles (52) is disposed in the chamber (56). The particles (52), when at rest, occupy a first portion (82) of the chamber (56) and define an unoccupied second portion (84) of the chamber. The particles (52) move back and forth between the first and second portions (82 and 84) of the chamber (56) in response to vibration of the vehicle part (12) and collide with each other and with the interior wall (58) defining the chamber to damp the vibration of the vehicle part.
