Description
Technical Field
The utility model relates to a field such as structure anti-wind, antidetonation, attenuator design, concretely relates to prevent rotatory damping rod system, slider formula attenuator, pendulum model attenuator.
Background
Under the action of wind load, the general high-rise building can simultaneously vibrate along the wind direction, the vertical wind direction and the torsion direction. Because of low relative rigidity, more prominent high-altitude wind load and the like of the high-rise building, the dynamic response caused by the wind load must be controlled, otherwise, the deformation and vibration of the structure caused by the wind acting on the structure can greatly influence the comfort of the use of the building, and even can cause the overall and local damage of the structure.
Additional damping becomes the most effective method of controlling building motion, one of the common forms is the tuned mass damper, which is usually placed mainly at higher floor locations of the building, operating in pendulum form, which is a large iron ball or concrete block weighing several hundred tons, with four sides connected by springs, consisting of masses, springs and damping system. When external force is transmitted to the building. The swinging of the building can transfer energy to the damper to enable the damper to swing simultaneously, the calculated damper can generate opposite swinging, the opposite swinging is just different from the swinging of the building, the vibration frequency of the damper is adjusted to be close to the main structure frequency, and the structure resonance characteristic is changed, so that the swinging of the building can be reduced, and the damping effect is achieved. In addition, compared with a pendulum type tuned mass damper, the 'slide block type' tuned mass damper cancels an upper hanging device, utilizes self inertia to slide, and saves installation space.
The principle of the pendulum type and slider type tuned mass damper relates to the motion of a large mass block, and the mass block can generate space swing and can also generate autorotation due to the influence of the torsional mode of a building in the motion process. If the rotation amplitude is too large, the whole damper system will be twisted, and the damper effect will be damaged or weakened.
Therefore, aiming at the tuned mass damper, the invention of the mass block anti-rotation device is important for limiting the rotation of the mass block during the movement, enabling the mass block to move more regularly and dissipating energy of the building rotation mode.

Detailed Description
The first embodiment is as follows: as shown in fig. 1: an anti-rotation damping bar system, comprising: more than 2 damping rods (4) which are arranged in parallel, a crossed oil return pipe (8),
Wherein the number of the damping rods is more than 2 (as shown in figure 1: a first damping rod (4) and a second damping rod (9)), the damping rods comprise: the damping rod cylinder body, the damping rod piston rod, the piston rod end spherical hinge and the damping rod cylinder body end spherical hinge are arranged, and the damping rod piston rod can stretch and retract relative to the damping rod cylinder body; under the initial condition, the elongation of the damping rods is kept equal;
the damping rods are connected with each other through a crossed oil return pipe (8) (namely, damping rod cylinders are connected with each other through the crossed oil return pipe), the crossed oil return pipe is a hose (mutual movement between the damping rods is not influenced), the crossed oil return pipe is communicated with the damping rod cylinders, hydraulic oil can flow through the crossed oil return pipe, when the damping rods stretch, the crossed oil return pipe can realize oil pressure balance inside two or more damping rods, namely, through the arrangement of the crossed oil return pipe, when 2 or more damping rods stretch and move, the stretching distance is equal;
the end part of the damping rod cylinder body is arranged at the end part of the damping rod cylinder body in a spherical hinge mode, and the end part of the piston rod is arranged at the end part of the piston rod in a spherical hinge mode;
a spherical hinge seat is arranged on the upright post (2) of the supporting frame, and a spherical hinge seat is arranged on the mass block (R);
the end spherical hinge of the damping rod cylinder body is arranged in a spherical hinge seat arranged on the support frame upright post (2), and the end spherical hinge of the piston rod is arranged in a spherical hinge seat arranged on the mass block (R).
A method of operation of an anti-rotation damping bar system:
when the building is acted by external forces such as wind load, the mass block moves due to inertia, and the damping rod passively moves in a telescopic manner. At this time, the oil pressure inside the damping rods 1 and 2 is balanced due to the crossed oil return pipe, and the piston rod extension length l of the damping rods 1 and 2 is equal to that of the damping rods 21＝l2So that the distance L between the fixed ends of the two damping rod cylinder bodies and the connecting point of the mass block1＝L2For the mass block, the instantaneous distance between the two connecting points and the upright post of the support frame is equal, namely, the mass block does not rotate. The whole system thus achieves the aim of preventing the masses from twisting.
In a second embodiment, as shown in fig. 2-3, a slider-type damper includes: several supporting frame upright columns (2), mass block R and arc base seat; an arc base is arranged between the upright posts (2) of the supporting frame
(the top surface of the arc-shaped base is a part of a spherical surface);

an anti-rotation damping rod system of the first embodiment is arranged between the mass block (R) and 1 support frame upright post (2) in the mass block (R);
1 damping rod is arranged between the mass block (R) and other supporting frame upright columns (2)
The damping rod is connected with the supporting upright post and the mass block by adopting a spherical hinge;
the bottom of mass block (r) is also arc-shaped and is slidingly arranged on said arc-shaped base (the direction of movement of the mass block in the plane may be any direction, i.e. when anti-seismic and anti-wind, it has a damping effect regardless of the direction of the external horizontal force).
The second example works as follows:
the sliding block type damper is installed in a high-rise building, and when the high-rise building is subjected to strong wind (or earthquake), the building swings correspondingly. At the moment, the mass block in the sliding block type damper can generate reverse movement with the building and generate sliding in the arc-shaped base due to self inertia and smooth bottom;
through the synergistic action of the damping rods, the vibration frequency of the mass block can be just adjusted to be close to the main structure frequency by the opposite movement of the mass block, and the structural resonance characteristic is changed, so that the swinging of the building can be reduced, and the damping effect is achieved.

The working of example three is as follows:

At the moment, the mass block in the pendulum type damper swings under the action of the suspension cable due to the inertia of the mass block; through the synergistic action of the damping rods, the displacement effect of earthquake or wind resistance is reduced through the energy consumption of the damping rods.
