Description
Technical field
The utility model is related to a kind of energy dissipative device of building structure, especially a kind of horizontal tuned mass damper, TMD.
Background technology
Tuned mass damper, TMD is one kind of the passive vibration damping control system of structure, it is by main structure and is attached in main structure
Minor structure composition, the minor structure include quality system, support system（Spring and damper）, and generally hang or be supported on knot
On structure.
The working mechanism of tuned mass damper, TMD is " with dynamic braking ", i.e., is controlled or weakened with the movement of a mass block
The movement of another mass block by adjusting dynamic characteristics, makes its natural frequency of vibration as possible close to the basic frequency of main structure or swashs
Frequency is encouraged, when main structure is vibrated by extraneous load incentive action, tuned mass damper, TMD will generate one and main knot
The opposite inertia force of structure direction of vibration is acted in main structure, so as to which the dynamic respons for making main structure are decayed and are controlled.
Viscous damper must be installed, viscous damper processing is cumbersome, difficult to install, rubs in general tuned mass damper, TMD
It is larger to wipe power.Therefore, it based on above-mentioned problem, needs to design a kind of horizontal tuned mass damper, TMD.
Utility model content
The purpose of this utility model is that solving above-mentioned problem, a kind of horizontal tuned mass damper, TMD is proposed, realize damping
It is synchronous with lubrication.
The technical solution of the utility model is：
Horizontal tuned mass damper, TMD, including wall base（1）, locking nut（2）, spring（3）, mass block（4）, damping liquid case
（5）, steel ball（6）, damping fluid（7）, screw rod（8）, the wall base（1）Positioned at outermost, two pieces of wall bases（1）Pass through screw rod（8）Even
It connects, junction locking nut（2）It is and tight；With wall base（1）The screw rod of lower part connection（8）Upper weld damping liquid case（5）, resistance
Buddhist nun's liquid case（5）Bottom be paved with steel ball（6）, damp liquid case（5）In fill damping fluid（7）；The steel ball（6）Top place matter
Gauge block（4）, mass block（4）With the wall base of both sides（1）Pass through spring（3）Connection.
Wherein, the screw rod（8）Quantity for three, two of which screw rod（8）With wall base（1）Lower part be connected, in addition
One screw rod（8）With wall base（1）Top be connected.
Wherein, the wall base（1）Bottom be fixedly linked with main structure.
Compared with prior art, the beneficial effects of the utility model are：The utility model is a kind of horizontal frequency modulation mass resistance
Damping fluid is fitted into damping liquid case by Buddhist nun's device, horizontal tuned mass damper, TMD, steel ball is put into case, damping fluid can play damping
Effect, and the lubricating oil of steel ball can be served as, reduce frictional force during mass block movement.This structure is easy to process, conducive to installation, rubs
Wipe power smaller.

Specific embodiment
The utility model is further described with embodiment below in conjunction with the accompanying drawings.
Embodiment
As depicted in figs. 1 and 2, horizontal tuned mass damper, TMD, including wall base 1, locking nut 2, spring 3, mass block 4,
Liquid case 5, steel ball 6, damping fluid 7, screw rod 8 are damped, if the outermost is wall base 1, two pieces of wall bases 1 are connected by screw rod 8, are connected
Place's locking nut 2 is simultaneously tight, and the damping liquid case 5 is welded on 1 lower part two screw rods 8 of wall base, and the screw rod 8 on 1 top of wall base plays
Connection function, the steel ball 6 are paved in damping liquid case 5, and the damping fluid 7 is filled in damping liquid case 5, and the mass block 4 is placed
On steel ball 6, and positioned at the center of two wall bases 1, the 3 quality of connection block 4 of spring and two wall bases 1.
The operation principle of the utility model is：
The utility model is arranged in by steel ball 6 in damping liquid case 5, realizes the movement of 4 very little frictional force of mass block, damping fluid
7 pairs of steel balls 6 play lubricating action, and damping fluid 7 plays damping action to mass block 4.
The use process of the damper of the utility model：
When external agent structure is by horizontal direction load excited vibration, horizontal tuned mass damper, TMD will generate one
The inertia force opposite with main structure direction of vibration is acted in main structure, so as to which the dynamic respons of main structure be made to decay and controlled
System.
