Description
Technical Field
The utility model belongs to the technical field of civil engineering structure damping antidetonation, concretely relates to harmonious quality damping device of horizontal migration type pendulum-type eddy current.
Background
In recent decades, with the rapid development of urban construction, various skyscrapers in cities are increasing, and wind vibration resistance and earthquake resistance technologies of skyscrapers are also rapidly developed, wherein Tuned Mass dampers (TMD for short) are widely applied to wind vibration and earthquake response control of skyscrapers.
Because the skyscraper has huge total mass and low natural frequency, the mass of the required TMD is generally in the hundred-ton grade, and the cost of the adopted steel spring is high, the TMD of the current skyscraper basically adopts a pendulum structure, such as a Taiwan 101 building, a Hangzhou bay bridge sightseeing tower and the like. The traditional pendulum TMD hangs a mass block on a structural member at the top end of a skyscraper with a certain cable length, and is assisted by a liquid damper to provide damping, because the skyscraper vibrates frequently under the action of wind power, the pendulum TMD also works very frequently, the requirements on the reliability and the service life of the liquid damper are very high, and the maintenance and replacement cost is also very high.

However, in practice, it has been found that, because the motion trajectories of the mass block and the permanent magnet are on a curved surface when the pendulum TMD is in operation, and the curved surface changes with the change of the cable length, in order to ensure stable performance parameters of the system, the copper plate and the magnetic conductive iron plate must be processed into curved surfaces that can be adjusted at any time so as to correspond to the motion curved surfaces of the mass block and the permanent magnet, which not only greatly increases the difficulty of processing and manufacturing the product, but also inevitably increases the complexity of the system structure, for example, the invention patent No. 201310080464.3 discloses a pendulum eddy current tuned mass damper device, which has a link structure arranged inside the adjustment frame of the copper plate and the magnetic conductive iron plate, and adjusts the angles and heights of the permanent magnet, the copper plate and the magnetic conductive iron plate synchronously by adjusting the link structure to adapt to the change of the swing radius, such adjustment structure and adjustment mode have complicated structure and troublesome operation, the space positions between the motion curved surfaces of the mass block and the permanent magnet and the matching curved surfaces of the copper plate and the magnetic conduction iron plate are necessarily relatively moved after adjustment, and the distance between the two curved surfaces is always changed in the swinging process, so that the size of eddy current damping generated in the copper plate is very unstable, the swinging amplitude of the mass block and the permanent magnet is limited, otherwise, the mass block and the permanent magnet are easily interfered with the copper plate, the whole vibration damping performance of the pendulum type eddy current TMD is influenced, and meanwhile, the manufacturing cost is greatly increased.
