Title
(EN) TUNED MASS DAMPING DEVICE
(FR) DISPOSITIF D'AMORTISSEMENT À MASSE ACCORDÉE
(ZH) 调谐质量阻尼装置
Abstract
(EN) A tuned mass damping device (100), comprising: a connecting rod (2) extending along a longitudinal direction; a weighting component (3) connected to a lower end of the connecting rod (2); and a top connection component (1), which is connected between an upper end of the connecting rod (2) and a tower cross beam (91) of a tower (9), and comprises an anti-rotation mechanism; the anti-rotation mechanism comprises: a transversely extending fixed plate (14) fixedly connected to the tower cross beam (91) by means of a longitudinally extending supporting member (11); a transversely extending first movable plate (15) provided below the fixed plate (14) and fixedly connected to the upper end of the connecting rod (2); and a pair of connection shafts (18) provided to be spaced apart from each other, each of the pair of connection shafts extending in a longitudinal direction; a lower end of the connection shaft (18) is fixedly connected to the first movable plate (15), and an upper end of the connection shaft (18) is inserted into the fixed plate (14) and is connected to the fixed plate (14) by means of a connector (16); the connector (16) comprises an outer sleeve (163) connected to the fixed plate (14), an inner sleeve (161) sleeved inside the outer sleeve (163) and connected to the connection shaft (18), and an intermediate elastic layer (162) provided between the inner sleeve (161) and the outer sleeve (163).
(FR) L'invention concerne un dispositif d'amortissement à masse accordée (100), comprenant : une tige de liaison (2) s'étendant le long d'une direction longitudinale ; un composant de pondération (3) relié à une extrémité inférieure de la tige de liaison (2) ; et un composant de liaison supérieur (1), qui est relié entre une extrémité supérieure de la tige de liaison (2) et une traverse de tour (91) d'une tour (9), et comprend un mécanisme anti-rotation ; le mécanisme anti-rotation comprend : une plaque fixe s'étendant transversalement (14) relié de manière fixe à la traverse de tour (91) au moyen d'un élément de support s'étendant longitudinalement (11) ; une première plaque mobile s'étendant transversalement (15) disposée au-dessous de la plaque fixe (14) et reliée de manière fixe à l'extrémité supérieure de la tige de liaison (2) ; et une paire d'arbres de liaison (18) disposés de façon à être espacés l'un de l'autre, chacune de la paire d'arbres de liaison s'étendant dans une direction longitudinale ; une extrémité inférieure de l'arbre de liaison (18) est reliée de manière fixe à la première plaque mobile (15), et une extrémité supérieure de l'arbre de liaison (18) est insérée dans la plaque fixe (14) et est reliée à la plaque fixe (14) au moyen d'un connecteur (16) ; le connecteur (16) comprend un manchon externe (163) relié à la plaque fixe (14), un manchon interne (161) emmanché à l'intérieur du manchon externe (163) et relié à l'arbre de liaison (18), et une couche élastique intermédiaire (162) disposée entre le manchon interne (161) et le manchon externe (163).
