ABSTRACT:
The invention is an apparatus for connecting a slender structure to a reference body. The apparatus comprises a link, that is connected to one end of the slender structure. The link is connected with a hinge at a second point of the link to the reference body with at least one degree of rotational freedom. A damper for damping motion of the link through at least one of the link's degrees of rotational freedom is connected between the link at a third point and the reference body. The device suppresses vibration waves travelling in the slender structure. A spring for resisting motion through the degree of rotational freedom may also be beneficially provided. The link, spring and damper may all act through one or two degrees of rotational freedom. The hinge can be either a pivot or a flex joint. The invention includes a method of selecting the parameters of the link, damper and spring assembly to optimize the suppression of vibration.
