Abstract: A damper for a structural tower having a space frame construction for high elevation and heavy load applications is disclosed, with particular application directed to wind turbines. The structural tower includes one or more dampers for damping resonant vibrations or vibrations generated by non-periodic wind gusts or sustained high wind speeds. The wind tower damper includes a fluid damper comprising a housing, elastomeric chamber, piston and damping fluid, wherein relative motion between the first and second structural members drive the fluid moving piston to pump the fluid and thereby dissipate unwanted motion in the tower.

Abstract: Vibration absorbers are provided which utilize a torsional spring and a dynamic mass to control vibrations that occur within the structure to which they are attached. Additionally, pipeline systems are provided which utilize such vibration absorbers includi ng a mass and a torsional spring to control the vibrations that occur within the pipeline system. In various embodiments of the present invention, the torsional spring is one or more elastomer elements coupled between the dynamic mass and a support frame to produce a spring for ce responsive to pivotal rotation of the dynamic mass relative to the support frame. In various embodiments, one or more elastomer elements arranged in series or in paralle l may be used as the torsional spring to provide a desired vibratory dampening characteristic for applications, such as pipelines. Use of such torsional springs may provide a more simplified design with less mechanical joints which may be less susceptible to failure in harsh environments.
