WIND TURBINE TOWER DAMPER

摘要

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.
