Abstract
A vibration attenuation apparatus may include a mass element, a bracket, and an elastomeric member. The mass element may include a first aperture. The bracket may include first and second portions. The first portion may be attached to a structure that transmits an input vibration. The elastomeric member may engage the mass element and the second portion of the bracket and may suspend the mass element relative to the bracket. The elastomeric member may include a shaft portion and a barb portion. The shaft portion may engage the second portion of the bracket. The barb portion may engage the first aperture of the mass element. The elastomeric member may include properties allowing the mass element to move relative to the bracket in response to the input vibration at a frequency that reduces an amplitude of the input vibration.
