Abstract:
An apparatus for damping vibration of a part of an automobile, said apparatus comprising:at least one container having a chamber defined by at least one interior wall, said at least one container being associated with the part of the automobile; and a plurality of particles disposed in said chamber, said particles when at rest occupying a first portion of said chamber and defining an unoccupied second portion of said chamber; said particles moving back and forth between said first and second portions of said chamber in response to vibration of the part of the automobile and colliding with each other and said at least one interior wall defining said chamber to damp the vibration of the part of the automobile through a momentum exchange between said particles and said at least one interior wall, through inter-particle dry friction and dry friction between said particles and said at least one interior wall, and through plastic deformation of the particles.
