Title (EN) DAMPER UNIT FOR A TOWER STRUCTURE
(FR) UNITÉ D'AMORTISSEMENT POUR STRUCTURE DE TOUR
Abstract:
(EN) The present invention relates to a damper unit for damping oscillations of a tower structure when secured thereto, the damper unit comprising a damper unit structure adapted for attachment to the tower structure, a pendulum structure, a suspension arrangement for suspending the pendulum structure from the damper unit structure such that the pendulum structure is allowed to displace from a neutral position for the pendulum structure, the suspension arrangement comprising one or more wires for suspending the pendulum structure, a sensor adapted for measuring oscillations of the tower structure, and tuning means configured for adjusting the natural frequency of the suspended pendulum structure in response to measured oscillations of the tower structure. The present invention further relates to an associated method.
(FR) La présente invention concerne une unité d'amortissement pour amortir des oscillations d'une structure de tour lorsqu'elle est fixée à celle-ci, l'unité d'amortissement comprenant une structure d'unité d'amortissement conçue pour être fixée à la structure de tour, une structure pendulaire, un agencement de suspension pour suspendre la structure pendulaire à la structure d'unité d'amortissement de telle sorte que la structure pendulaire puisse se déplacer à partir d'une position neutre pour la structure pendulaire, l'agencement de suspension comprenant un ou plusieurs câbles pour suspendre la structure pendulaire un capteur conçu pour mesurer des oscillations de la structure de tour, et des moyens de réglage configurés pour ajuster la fréquence naturelle de la structure pendulaire suspendue en réponse à des oscillations mesurées de la structure de tour. La présente invention concerne en outre un procédé associé.
