A vibration absorber damper for a rotatable structure which is nominally cyclic symmetric, the cyclic symmetric structure having a hub portion having a rotational axis and a plurality of radial members radially extending from the hub portion, the hub portion having a groove extending circumferentially about the rotational axis, the groove being positioned proximal to the rotational axis relative to the plurality of radial members, the vibrational absorber damper comprising: a ring member having: a plurality of repetitive cellular structures each defining a hollow interior section, each of the plurality of repetitive cellular structures comprising a distal wall, a proximal wall, and a pair of sidewalls interconnecting the distal wall with the proximal to form the hollow interior section; and a plurality of deformable members each extending from the ring member and disposed in a corresponding one of the plurality of repetitive cellular structures, each of the plurality of deformable members configured to interact with the nominally cyclic symmetric structure to damp vibration thereof, each of the plurality of deformable members having a first stiffness in a radial direction relative to the rotational axis and a second stiffness in a direction orthogonal to the radial direction, the second stiffness being less than the first stiffness, at least one of the plurality of deformable members comprising an elongated portion having first end extending from one of the distal wall, the proximal wall, and the pair of sidewalls, the at least one of the plurality of deformable members comprising an enlarged portion disposed on a second end of the elongated portion opposite the first end, the enlarged portion is shaped to complement at least one of the distal wall, the proximal wall, and the pair of sidewalls to limit movement of the deformable member in response to application of a force, and the enlarged portion comprising a central valley opposing a protrusion formed in at least one of the distal wall, the proximal wall, and the pair of sidewalls. a plurality of repetitive cellular structures each defining a hollow interior section, each of the plurality of repetitive cellular structures comprising a distal wall, a proximal wall, and a pair of sidewalls interconnecting the distal wall with the proximal to form the hollow interior section; and a plurality of deformable members each extending from the ring member and disposed in a corresponding one of the plurality of repetitive cellular structures, each of the plurality of deformable members configured to interact with the nominally cyclic symmetric structure to damp vibration thereof, each of the plurality of deformable members having a first stiffness in a radial direction relative to the rotational axis and a second stiffness in a direction orthogonal to the radial direction, the second stiffness being less than the first stiffness, at least one of the plurality of deformable members comprising an elongated portion having first end extending from one of the distal wall, the proximal wall, and the pair of sidewalls, the at least one of the plurality of deformable members comprising an enlarged portion disposed on a second end of the elongated portion opposite the first end, the enlarged portion is shaped to complement at least one of the distal wall, the proximal wall, and the pair of sidewalls to limit movement of the deformable member in response to application of a force, and the enlarged portion comprising a central valley opposing a protrusion formed in at least one of the distal wall, the proximal wall, and the pair of sidewalls. <EOS>
