ABSTRACT:
A device for damping vibration of a vibrating structure, particularly a helicopter cyclic control system, comprises a straight tubular shaft having a metal weight retained within the inside bore of one end, the remainder of the shaft being unweighted, and two elastomeric lined mounting brackets for securing the unweighted portion of the shaft to the vibrating structure, the bracket closest to the unweighted shaft end holding the shaft end with a tighter fit than the other bracket.
