Description

Damping Device

The present invention relates to a vibration isolation device.

Recently, damping technology has been applied as an alternative to existing seismic design beyond the research stage as a method to control excessive response of structures caused by dynamic load such as wind or earthquake. Conventional seismic design can be categorized into two methods: increase of strength and increase of ductility. In the seismic design due to the increase of the strength, an excessively large member is used, which is uneconomical, and there is a disadvantage that it can cause a large loss of life due to the sudden brittle fracture pattern of the structure. In addition, seismic design due to increased ductility can effectively reduce the magnitude of seismic load by absorbing seismic energy by plastic deformation of structural member, but it is difficult to repair / reinforce after earthquake and installation cost is high.

On the other hand, the vibration suppression technology protects the structure by concentrating the vibration energy introduced into the structure to the additional vibration suppression device. Therefore, the damping technique prevents or minimizes the plastic deformation of the structure itself, although the initial cost is comparable or slightly higher than that of a general earthquake-resistant structure. Therefore, the vibration suppression technique has the advantage of easy maintenance and reinforcement after the earthquake, and effectively exterminates or reduces the ground vibration transmitted to the structure, thereby excellently protecting various human resources and goods stored therein. Damping technology has mainly been applied to important facilities such as bridges in the earthquake-stricken area, hospital nuclear power plants, etc., and its application has been widely expanded after proving its excellence in actual earthquakes. Particularly, as shown in Fig. 5, when the horizontal axis is oscillated transversely due to earthquake load or wind load, when the horizontal displacement on each side is combined, the displacement difference between the low and high layers becomes large. The need for vibration suppression technology is gradually expanding.

The vibration suppression device, which is the core of this vibration suppression technology, absorbs the seismic load or wind load that flows into the structure by the energy dissipation function, thereby reducing the deformation of the structure. By dynamically analyzing this, the damping capacity of the entire structure is improved, and the effect of displacement reduction is obtained in the response spectrum. Since the damper acts to dissipate the energy by deformation, it is installed in a place where the displacement of the structure occurs largely, and is generally installed in the form of a brace between layers. The difference between general structural bracing and bracing bracing is to increase the stiffness of the structural bracing, while the bracing bracing serves to increase the damping. The increase in stiffness with structural bracing reduces the period, which increases the seismic load acting on the structure even if the displacement is reduced. On the other hand, the increase of the decrease due to the braking force for braking has the effect of reducing both the displacement and seismic load of the structure.

However, the occurrence of earthquakes is very irregular, so it is difficult to predict accurately. Most of the earthquakes that have occurred so far are small frequency earthquakes, and large earthquakes are rare. In other words, it can be said that the earthquake has a weak vibration characteristic of high frequency and a strong vibration characteristic of low frequency. Thus, it is not easy to select an attenuator having a proper damping capacity in the design of the damper of the vibration damper, since it is difficult to predict the occurrence of the earthquake as a stochastic event. Particularly, as disclosed in the patent documents of the following prior art documents, the vibration damping device according to the related art has a problem that when the vibration damping device is composed of one kind of damper and exceeds a certain distance, the damping force can not be further exerted, do. Furthermore, when a large earthquake occurs, it is difficult to obtain a sufficient damping effect only by an oil damper. Further, the vibration damping device according to the related art has a problem in that it can not be installed in a narrow space (for example, inside a wall) according to the diameter of a damper (cylinder, piston, etc.)

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view of a vibration dampening panel according to an embodiment of the present invention; FIG.

As shown in FIG. 1, the vibration docking house 100 according to the present embodiment is installed in a structure 200 including opposite first and second nodes 210 and 220, A first link 110 connected to the node 210 and a second link 120 having one end connected to the second node 220 are formed in a closed curve such that a predetermined region T is defined therein, The support member 130 is connected to the other end of the first link 110 and the other end is connected to the other end of the second link 120. The support member 130 has a rigidity, The attenuator 140 and the yielding attenuator 150 coupled to the support member 130 and spaced apart by a predetermined distance D from each other.

The vibration dampers 100 according to the present embodiment are provided with the viscous damper 140 and the yielding damper 150 so that the support member 130 is deformed according to the magnitude of the displacement occurring in the structure 200, By operating the viscous damper 140 or the yielding damper 150, seismic loads or wind loads of various sizes can be efficiently absorbed. In addition, the vibration docking house 100 according to the present embodiment is basically installed in the structure 200 (building, etc.). Here, the structure 200 may include a first node 210 and a second node 220 facing each other. At this time, although the first node 210 and the second node 220 are shown diagonally facing each other, the first node 210 and the second node 220 are not necessarily arranged to face diagonally if they are disposed so as to face each other in the structure 200. Also, the structure 200 is generally shown as a rectangle, which may refer to a beam, a bottom plate, or a wall side wall or the like provided in each layer of the building. The first and second links 110 and 120 and the support member 130 will be described in detail with reference to the structure 200 and the first and second nodes 210 and 220.

The first and second links 110 and 120 are connected to the support member 130 to transmit the displacement of the structure 200 to the viscous damper 140 and the yielding damper 150. The first and second links 110 and 120 may be formed of, for example, a cable or a rigid frame in the form of a beam. have.

Specifically, the first link 110 has one end connected to the first node 210, and the other end connected to one side of the support member 130. The second link 120 has one end connected to the second node 220 and the other end connected to the other side of the support member 130. That is, the first link 110 and the second link 120 extend from the first node 210 and the second node 220, respectively, and are connected to both sides of the support member 130. The longitudinal direction X of the first link 110 and the longitudinal direction Y of the second link 120 may be parallel to each other.

The support member 130 supports the viscous damper 140 and the yielding damper 150 to transmit the displacement of the structure 200 to the viscous damper 140 and the yielding damper 150, And acts to attenuate the displacement of the structure 200 by the elastic force due to its own rigidity. Here, the support member 130 is formed as a closed loop, and may be formed in an elliptical shape, for example. That is, the support member 130 may be formed in an elliptical shape having a relatively long long axis A and a relatively short minor axis B perpendicular to the long axis A. As described above, the support member 130 is formed in a closed curve (elliptical shape), and a predetermined region T is provided therein. The viscous damper 140 and the breakdown type attenuator 150 are disposed in the predetermined region T. One side of the support member 130 is connected to the other end of the first link 110 (opposite end of one end connected to the first node 210), and the other side of the support member 130 is connected to the second link 120 (The opposite end of one end connected to the second node 220). More specifically, when the support member 130 is elliptical, one end of the long axis A of the support member 130 is connected to the other end of the first link 110, and the other end of the long axis A of the support member 130 May be connected to the other end of the second link (120).

On the other hand, the viscous damper 140 and the yield type attenuator 150 are disposed in a predetermined region T of the support member 130. When a tensile force is applied to the support member 130 in the longitudinal direction of the first and second links 110 and 120 (in the direction of the long axis A of the support member 130) due to the displacement of the structure 200, The displacement of the structure 200 is transmitted to the viscous damper 140 and the yielding damper 150 disposed in the predetermined region T while the support member 130 is bent. As a result, the viscous damper 140 and the yielding damper 150 can receive and attenuate the displacement of the structure 200 through the support member 130. In addition, since the support member 130 has rigidity, the displacement of the structure 200 can be attenuated by the elastic force of the support member 130 itself. The resilient force of the support member 130 due to the rigidity can act as a restoring force of the viscous damper 140. In addition, since the support member 130 has a rigidity of a predetermined size or more, the rigidity of the structure 200 can be increased.

Meanwhile, the support member 130 may be formed of a steel plate bent to have rigidity, for example, a plate spring. However, the support member 130 may be formed of any type of material known in the art .

The viscous damper 140 dissipates the energy of the structure 200 due to viscosity, and is suitable for a weak vibration characteristic that generates a displacement of less than a predetermined range. The viscous damper 140 is disposed in a predetermined region T of the support member 130 and both ends of the viscous damper 140 are coupled to the support member 130. Accordingly, the viscous damper 140 can attenuate the displacement generated when the support member 130 is deformed.

Specifically, the direction in which the viscous damper 140 operates may be perpendicular to the longitudinal direction (X, Y) of the first and second links 110, 120. The tensile force is applied to the support member 130 in the longitudinal direction of the first and second links 110 and 120 (in the direction of the long axis A of the support member 130) When the displacement occurs in the support member 130 perpendicular to the longitudinal direction of the first and second links 110 and 120 (in the direction of the minor axis (B) of the support member 130), the viscous damper 140 attenuates the displacement .

On the other hand, a plurality of viscous damper 140 may be provided. By providing a plurality of viscous dampers 140 as described above, it is possible to easily realize an optimal damping capacity with a small diameter, but also to realize a damping capacity such as an attenuator with a large diameter and to install the damping capacity in a relatively narrow space have.

The yielding type attenuator 150 plays a role of dissipating vibrations due to yielding of a metal material or the like and is suitable for responding to strong vibration characteristics that cause displacement exceeding a predetermined range. Here, the yield type attenuator 150 is disposed in a predetermined region T of the support member 130, and two mutually opposing portions are spaced apart by a predetermined distance D from each other. Therefore, when the displacement of the structure 200 occurs over a predetermined range, the two yielding attenuators 150, which face each other, contact each other to generate a displacement occurring when the support member 130 deforms Can be attenuated.

In particular, the yield type attenuator 150 may be coupled to the end of a rod 160 coupled to the support member 130. That is, the two yielding attenuators 150 can be coupled to the rod 160 so as to face each other. At this time, the two yielding type attenuators 150 facing each other are spaced apart from each other by a predetermined distance D perpendicularly to the longitudinal direction of the first and second links 110 and 120 (in the direction of the short axis B of the support member 130) do. The tensile force is applied to the support member 130 in the longitudinal direction of the first and second links 110 and 120 (in the direction of the long axis (A) of the support member 130) When the support member 130 is displaced perpendicularly to the longitudinal direction of the first and second links 110 and 120 (in the direction of the minor axis (B) of the support member 130), two mutually opposing, The attenuator 150 may contact each other to attenuate the displacement.

On the other hand, by adjusting the length of the rod 160, the predetermined distance D between the two support members 130 facing each other can be adjusted. Thus, it is finally possible to adjust the magnitude of the displacement at which the yielding attenuator 150 begins to attenuate.

In addition, a plurality of mutually opposing two of the yielding type attenuators 150 may be provided. That is, when two mutually opposing yielding attenuators 150 are defined as one yielding attenuator set 155, the plurality of yielding attenuator sets 155 may be provided. By coupling a plurality of sets of the breakdown type attenuators 155 in this manner, it is possible to easily realize an optimum damping capacity with a small diameter, but also to realize a damping capacity such as an attenuator with a large diameter and to be installed in a relatively narrow space There are advantages.

The viscous damper 140 and the yield type attenuator 150 are disposed on one side of the support member 130 when the two breakdown type dampers 150 opposed to the viscous damper 140 are provided as described above. To the other side.

The vibration damping device 100 according to the present embodiment includes the viscous damper 140 and the yielding damper 150 to absorb seismic loads and wind loads of various sizes. .

FIGS. 2 to 4 are front views showing the operation of the vibration isolation device according to the embodiment of the present invention.

2, before the displacement occurs in the structure 200 due to the earthquake load or the wind load, the support member 130 is not deformed, and the viscous damper 140 does not operate. Also, since the two mutually opposing yielding attenuators 150 are spaced apart by a predetermined distance D, the yielding attenuator 150 also does not operate.

3, the distance between the first node 210 and the second node 220 increases as the displacement occurs in the structure 200 by a predetermined amount or less (D1) A tensile force is applied to the first and second links 110 and 120 connected to the first and second nodes 210 and 220, respectively. As the support member 130 is bent by the tensile force, the displacement of the structure 200 is attenuated by the elastic force due to the rigidity of the support member 130 itself. At the same time, the viscous damper 140 attenuates the displacement generated when the support member 130 deforms. That is, when a displacement occurs in the support member 130 perpendicular to the longitudinal direction of the first and second links 110 and 120 (in the direction of the minor axis (B) of the support member 130), the displacement is transmitted to the viscous damper 140 . Therefore, when the displacement of the structure 200 is less than a predetermined range, the displacement of the structure 200 can be attenuated by the support member 130 and the viscous damper 140. However, two mutually opposing yielding attenuators 150 maintain a state of being separated from each other (D ').

Meanwhile, when the displacement of the structure 200 is restored to the position shown in FIG. 2, the elastic force of the support member 130 due to the rigidity can act as a restoring force of the viscous damper 140. That is, the viscous damper 140 can be restored to the state before the operation by the elastic force of the support member 130.

Next, as shown in FIG. 4, as the distance between the first node 210 and the second node 220 increases as the displacement of the structure 200 occurs over a predetermined range (D2) A stronger tensile force is applied to the first and second links 110 and 120 connected to the first and second nodes 210 and 220, respectively. The support member 130 is bent by this tensile force. At this time, the support member 130 attenuates the displacement of the structure 200 by its own elasticity, and the viscous damper 140 attenuates the additional displacement caused by the deformation of the support member 130. In addition, two mutually opposing yielding type attenuators 150 contact each other to attenuate the displacement generated when the support member 130 is deformed. That is, when a large displacement occurs in the support member 130 in a direction perpendicular to the longitudinal direction of the first and second links 110 and 120 (in the direction of the minor axis (B) of the support member 130), this displacement is transmitted to the viscous damper 140 And the yielding attenuator 150 are attenuated together. Accordingly, when the displacement of the structure 200 occurs in the structure 200 during the earthquake, the displacement of the structure 200 can be attenuated by the support member 130, the viscous damper 140, and the yielding damper 150.

As a result, the vibration suppression apparatus 100 according to the embodiment of the present invention has an advantage of effectively absorbing various types of earthquake energy.

On the other hand, the "predetermined range" of the displacement, which is a reference of operation of the yield type damper 150, is set to a necessary value in consideration of the viscous damper 140 and the attenuation capacity of the yield type attenuator 150 at the time of designing the vibration isolation device 100 .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
