Damping control device of composite sealed tuned mass damper

Abstract

The invention discloses a damping control device of a composite sealed tuned mass damper, which is used for wind vibration or seismic response damping control of building structures or electromechanical equipment, and belongs to the technical field of structure vibration control. The damping control device of the composite sealed tuned mass damper mainly comprises a tuned mass block, a spring, viscous liquid and rotating wheels, wherein the viscous liquid is filled in a sealed containment cavity and used for providing damping; the frequency of the device can be changed by regulating the rigidity of the tuned mass block and the spring; and the universal rotating wheels at the top end and the bottom end of the mass block can ensure the damping control effect of each direction and avoid shake of the mass block at the same time. The device has definite force transfer path and control target, control adjustability, wide application range, simpleness of installation and full closed operation, is easily started, can realize free maintenance once debugging and installation are completed, and has good durability and high application and popularization values.

Description

technical field [0001] The invention relates to a vibration reduction control device for a composite sealed type tuned mass damper, which is used for vibration control of wind vibration or earthquake response, and belongs to the technical field of structural vibration control. Background technique [0002] Tuned mass damping control belongs to structural passive control. As the core component of the tuned mass damping control device, the tuned mass damper, TMD for short, is a substructure attached to the main structure, consisting of a mass block, a spring, and a damping device. When there is an external excitation, the inertial force generated by the relative motion of the TMD system reacts on the structure to control the vibration of the structure, and the damper in the TMD system will also play a role in energy consumption, thereby achieving the purpose of reducing the vibration response of the structure. TMD has little impact on building functions and is easy to install...
