Tuned mass damper structure with continuously variable frequency
The invention discloses a tuned mass damper structure with continuously variable frequency. The tuned mass damper structure comprises a main mass block, a guide mechanism, a constant-stiffness elastic support, a damping unit and a base, wherein the main mass block and the base together constitute a main support structure; the tuned mass damper structure further comprises a stiffness-adjustable elastic support positioned between the main mass block and the base; the stiffness-adjustable elastic support comprises an elastic beam, a sliding part and a fastening piece; the right end of the elastic beam is fixedly mounted on the base; the sliding part is mounted on the main support structure in a position-adjustable manner and can slide in the longitudinal direction of the elastic beam; the fastening piece is used for fixing the sliding part on the main support structure after the sliding part slides to a set position. The tuned mass damper structure has the advantages that stepless adjustment of the support stiffness can be realized in a larger range, tuned mass damper products with the same models can meet vibration damping requirements of base structures of different vibration frequency and also can be used for reducing vibration of base structures with time variable vibration frequency.
