Description

Technical Field

[0001] The present invention relates to the fields of structural wind resistance, seismic resistance, damper design, etc., and particularly relates to a non-suspended multi-domain controllable oil film tuned mass damper and a building. Background Art

[0002] Dampers are very common components in the construction field, such as: CN211257389U, CN210482630U, CN103629291A, etc.

[0003] As a common damper, a tuned mass damper generally includes: a spring, a mass block, and a damping unit. Its working principle is: when the main structure of a building vibrates, the mass block of the tuned mass damper will generate an opposite inertial force, so that the vibration of the main structure of the building is attenuated.

[0004] Common tuned mass dampers are usually large in volume and usually adopt a "pendulum type" structure, usually occupying the space of several floors, directly reducing the usable area of high-rise buildings. According to this situation, inventing a non-hoisting tuned mass damper can reduce the overall height of the damper device, save floor space, and improve the utilization rate of high-rise buildings, which has become an urgent technical problem to be solved. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a non-suspended multi-domain controllable oil film tuned mass damper and a building.

[0012] The oil pump system is connected to each bottom oil outlet through an oil pipeline, and a valve is also provided between the oil pump and the oil pipeline; the lubricating oil is transported to the bottom oil outlet through the oil pipeline, and an oil film can be formed at the bottom of the mass.

[0013] Among them, a number of damping rods are provided between the mass and the support frame;

Specific implementation manners

[0032] First embodiment: As shown in the attached Figures 1 to 4 drawings, a non-suspension multi-domain controllable oil film tuned mass damper includes: a mass block ①, a damping rod ④, a support frame ⑥, a base ⑨, and a controllable oil film sliding system ②;

[0033] Among them, the upper surface of the base ⑨ is a spherical surface and is matched and fitted with the bottom surface of the mass block; within the contact range between the upper surface of the base ⑨ and the mass block, a base slide plate ⑧ is installed, and the base slide plate ⑧ is made of a material with a low friction coefficient and high strength; the outer edge of the upper surface of the base is a base limit ⑦, which is used to limit the sliding range of the mass block and prevent the mass block from sliding out of the spherical surface area to prevent danger;

[0034] Among them, the mass block ① and the controllable oil film sliding system are integrally constructed;

[0035] Among them, the controllable oil film sliding system ② includes: an oil pump system located above the mass block and a sliding system at the bottom of the mass block;

[0036] Among them, the oil pump system stores lubricating oil;

[0037] Among them, the bottom sliding system includes: an inner contact partition an outer contact partition (the inner contact partition is inside the outer contact partition ), several bottom oil outlet holes The inner contact partition The outer contact partition slightly protrudes from the bottom surface of the mass block and is in direct contact with the base slide; the bottom oil outlet holes are arranged at the lower part of the mass block;

[0038] The oil pump system is connected to each bottom oil outlet hole through an oil delivery pipe respectively. A valve is also arranged between the oil pump and the oil delivery pipe to achieve oil supply at different rates / different amounts for each oil delivery pipe . The lubricating oil is transported to the bottom oil outlet holes through the oil delivery pipes and forms an oil film at the bottom of the mass block;

[0039] Among them, several damping rods ④ are arranged between the mass block ① and the support frame ⑥;

[0040] Among them, the structure of the damping rod ④ is: the damper includes a piston rod and an oil cylinder. The piston rod is hinged to the mass block ① through a damping rod-mass block connecting ball joint ③, and the oil cylinder is hinged to the support frame ⑥ through a damping rod-support frame connecting ball joint ⑤.

[0041] Furthermore, it also includes: an oil return bin The bottom oil outlet holes are arranged inside the outer contact partition , and an oil return bin is arranged outside the outer contact partition The oil return bin is connected to the oil pump system . A suction oil pump ( not shown in ) can be arranged on the pipeline connecting the oil return bin and the oil pump system. Figure 1

[0042] It should be further noted that: there is a multi-domain controllable oil film sliding system on the mass block; the bottom contact profile of the mass block is a spherical surface, which can be closely attached to the bottom base and move relatively.

[0043] It should be further noted that: the working process of the controllable oil film sliding system:

[0044] 1) The lubricating oil passes through the oil delivery pipe inside the mass block ​Through the bottom oil outlet It flows out, forming an oil film at the bottom of the mass block. The oil film can reduce the frictional force at the start of the mass block movement. And by controlling the amount of oil injection and the injection rate (the oil outlet area corresponding to each oil pipeline can be adjusted), the thickness of the oil film on the contact surface can be changed, thereby adjusting the damping of the contact surface.

[0045] 2) There is a certain gap at the bottom of the outer contact partition. During the sliding process of the mass block, the lubricating oil can flow through the gap to the oil return chamber (low-pressure area) outside the outer contact partition. The bottom of the oil return chamber is in contact with the base slide plate, and the oil return pipe connects the oil return chamber and the oil pump system, which can re-inject the oil in the oil return chamber back into the oil pump system to achieve the circular flow of the lubricating oil.

[0046] It should be further noted that: both the damping rod-mass block connecting ball joint ③ and the damping rod-support frame connecting ball joint ⑤ adopt ball joints, which can meet multi-directional rotation. During the sliding process of the mass block, the damping rod will synchronously perform passive telescopic movement and provide corresponding resistance to resist the impact force of the mass block. The damping force of the damping rod can be adjusted by changing the oil pressure and other methods.

[0047] It should be further noted that: the support frame ⑥ consists of the support frame column the support frame cross beam

[0048] A non-suspended multi-domain controllable oil film tuned mass damper is installed in a high-rise building. When the building is affected by strong winds, the building will generate corresponding swings. At this time, due to its own inertia and the smooth bottom of the mass block of this device, it will move in the opposite direction to the building. Through the synergistic effect of the damper, the opposite movement of the mass block can just adjust its vibration frequency to near the main structure frequency, changing the structural resonance characteristics, so the swing of the building itself can be reduced to achieve the shock absorption effect.

[0049] The above-mentioned embodiments are the preferred embodiments of the present invention, which are only used to conveniently illustrate the present invention and do not impose any form of limitation on the present invention. Any person with ordinary knowledge in the technical field to which the present invention pertains, if without departing from the technical features of the present invention, makes local modifications or equivalent embodiments by using the technical content disclosed in the present invention and without departing from the technical feature content of the present invention, still fall within the scope of the technical features of the present invention.
