Title:
LEAD SCREW DRIVEN ACTIVE LIQUID TUNED MASS DAMPER
Document Type and Number:
WIPO Patent Application WO/2020/155638
Kind Code:
A1
Abstract:
The present invention relates to the field of suppression of vibration in a system, in particular to a lead screw driven active liquid tuned mass damper. The lead screw driven active liquid tuned mass damper comprises a drive housing, a support plate and an active control device, wherein the active control device comprises a driver, a moving mass body, a lead screw and a bearing; and the drive housing is fixed to a controlled object, the support plate is fixed inside the drive housing, the driver is mounted on the support plate, the driver is connected to the lead screw, the other end of the lead screw is fixed to an outer wall of the drive housing via the bearing, and the moving mass body is connected to the lead screw. The present invention solves the problems in the prior art of the control effect of a traditional TMD/AMD on structural vibration being limited, a passive tuned rotational inertia damper being low in control application robustness, complex in frequency modulation technology and small in application range, and a damper of an active unchangeable drive mass block having the risk of invalidation when a structure changes, and being low in flexibility.
