  • Publication number: 20230212831
    Abstract: A passive damper for damping relative lateral movement between a tensioned cable or other oblong member and a support structure includes a first fixture element rigidly connected to the cable or other oblong member, a second fixture element rigidly connected to the support structure, and at least one rotational damping device arranged between the first and second fixture elements . The rotational damping device is configured to translate the relative lateral movement into relative rotational moment between at least two arms of the rotational damping device that are connected at a rotational joint with a damping pad clamped in between the at least two arms The rotational joint has a rotational axis (Y) substantially parallel with a longitudinal axis (X) of the cable.

  • Patent number: 9260860
    Abstract: A passive damper with a first set of parallel disposed plates and a second set of parallel disposed plates, that overlap one another in an alternating fashion at a rotational joint with damping pads between the plates. The rotational joint comprises a pin or bolt inserted through apertures in the plates and there is a connection hole in each of the plates of the second set of plates for receiving a connection pin (6) therein for connecting the second set of plates to a members of a structure. The connection holes in a selection of the plates of the second set of plates is shaped and dimensioned to provide a predetermined amount of clearance with said connection pin so that the connection pin can move inside the connection holes of the selection of plates taking part in the damping action of the damper.

  • Patent number: 8621791
    Abstract: A damper has two sets of first elongate members, second elongate members that are connected so that they can rotate and that connect the first elongate members to one another, and damping members which attenuate the relative movement between the first elongate members and the second elongate members. The respective first joints of each of the first members are connected to the first connection members and the second connection members so that they can rotate. The first joint of the first elongate member, the first joints of the other first elongate members, and each of the second joints are located along the common axes.

  • Patent number: 8622373
    Abstract: A bearing (1) comprising a block (10) of flexible material, having two end surfaces (11, 12); and a first fixture element (20) and a second fixture element (30) connected at each of the end surfaces (11, 12); wherein at least one rotational damping device (40) is arranged between the first and second fixture elements (20, 30), the bearing thus providing high dampening between structural parts of a structure, such as buildings, bridges, elevated highways, and mechanical systems (machinery).
