Abstract (en)
[origin: WO2019201471A1] The invention relates to a new type of independently damping pendulum suspension for pendulum dampers for use in tall slender constructions and technical installations, more particularly wind turbines. The invention relates more particularly to a Cardan joint equipped with damping elements and mounted at the other end opposite the pendulum mass, which Cardan joint is able, despite the small motions there, to sufficiently damp the oscillations of the pendulum produced by disturbing frequencies.
