Embodiment Construction

[0022] Fix screed plate 6 on main structure 1, such as figure 1 shown. Upper bearing seat 7 is fixed on the flat plate. The deep groove ball bearing 11 with a dust cover is fixed in the shaft hole of the upper bearing housing with the retaining ring 10, the spacer ring 12 and the circlip 13 for the hole, and is clamped by the circlip 9 for the shaft, see Figure 4 shown. The two bearings of the cross-shaped universal joint 8 penetrate into the deep groove ball bearings (for the structure of the cross-shaped universal joint, see Figure 6 ), which can rotate freely in one plane. Lower bearing seat 14 is suspended on the two bearings of another vertical direction of cross universal joint. Deep groove ball bearings are also installed between the lower bearing seat and the cross universal joint bearing, such as figure 2 As shown in the side view, the lower bearing seat can be suspended under the cross-shaped universal hinge and rotate freely in another vertical plane. Conne...

Abstract

The present invention relates to damping controller for suspended tuning mass damper used for tower type building structure. The damping controller has rigid suspending rod, rather than flexible wire, for supporting balance weight to avoid its torsion and jitter; cross universal hinge for connecting the main structure and the rigid suspending rod and makes it possible to control the vibrations in different directions; and friction damping fin, rather than piston type damper, mounted in the cross bearing site to provide damping. The present invention can perform damping and vibration controlling stably and effectively, and has convenient regulation of three control parameters and no need of maintenance.

Description

technical field [0001] The invention relates to a suspension-type tuned mass damper vibration reduction control device, especially a vibration reduction control device that can avoid the torsion and vibration of the counterweight and can be used for a long time without maintenance, and can be used in tower building structures Etc. vibration damping control. Background technique [0002] The suspended tuned mass damper vibration control device (Tuned Mass Damper, referred to as TMD) is installed on the building structure, using the principle of resonance, the vibration energy of the main structure is absorbed and transferred to the control device, thereby reducing the wind vibration of the building structure And earthquake response, there have been many applications at home and abroad. Calculation analysis and practice have proved that when the TMD quality is appropriate, the frequency of the TMD control device is close to the frequency of the main structure, and the damping...
