Abstract

The damper (40) and pendulum rod (3) pivot form a closed unit made up of one or more elastomer modules, possibly supplemented by additional mechanical or hydraulic dampers. The modules have distance disks to control their stiffness and are spread round the rod pivot point. The rod (3) itself should be flexible and possibly made up of elastomer components, using several rods and their pivots if so desired. The wind powerstation comprizes tower and machinery house (39) equipped with the rotor blades (35) and the damper load (1) should be arranged above the rod pivot, notably in the machine house (39).
