Abstract
A damper element and a vibration dampening system including a plurality of the stacked damper elements, are provided. The damper element(s) may be used in a body opening in a rotating blade in a turbine. The damper elements include a head member having an at least partially ramped surface, and a plurality of flexible legs extending from the head member. Each flexible leg includes a radially extending body section having an end section, and the end section has an outer end surface and an inner end surface. Centrifugal force caused by rotation of the rotating blade cause the head member of an adjacent damper element to force the outer end surfaces of the plurality of flexible legs into frictional engagement with an inner surface of the body opening to dampen vibration. In certain embodiments, an elongated body may extend through an opening in the head member of the damper element(s).
