Description

자기유변 감쇠기와 감쇠판을 이용한 바닥판 구조물의 진동 제어장치{Vibration control device for building structure by MR-damper and damping plate}Vibration control device for bottom plate structure using magnetorheological damper and damper plate

본 발명은 건축물의 구조체가 받은 충격에 의한 진동을 감쇠시켜서 건축물 전체로 전이되는 충격량을 감소시킬 수 있는 자기유변 감쇠기와 감쇠판을 이용한 바닥판 구조물의 진동 제어장치에 관한 것이다.The present invention relates to a vibration control device for a floor plate structure using a magnetic rheological damper and a damping plate that can attenuate the vibration caused by the shock received by the structure of the building to reduce the amount of impact transmitted to the entire building.

건축물은 철근콘크리트 또는 강철프레임 등을 자재로 하는 기둥 및 보 등을 뼈대로 한 조립 구조체로써, 외부로부터 가해지는 충격은 뼈대인 기둥 및 보 등이 지탱하면서 흡수한다.The building is an assembly structure made of pillars and beams made of reinforced concrete or steel frame, etc., and the shocks from the outside are absorbed while being supported by the pillars and beams of the skeleton.

여기서, 보는 둘 이상의 기둥에 고정되면서 건축물이 받는 하중을 다수의 기둥으로 분산시킨다. 또한, 보는 건축물이 충격을 받으면 자체적으로 진동하면서 기둥으로의 충격 분산과 더불어 건축물이 받는 충격을 소멸시킨다.Here, the beam is fixed to two or more pillars while distributing the load received by the pillars. In addition, when the building is impacted, the building vibrates itself, dissipating the impact to the column and extinguishes the impact.

건축물의 바닥구조를 이루는 바닥판은 층간을 경계하는 보 상에 안착 지지된다. 따라서, 바닥판에 가해지는 충격은 보에 그대로 전달되면서, 전술한 과정과 같이 기둥으로의 분산과 보의 자체 진동으로 소멸한다. 물론, 바닥판 및 보는 건 축물이 받게 될 예상 충격을 충분히 고려하여 설계될 것이다.The floor plate which forms the floor structure of the building is supported by being seated on beams that border the floors. Therefore, while the impact applied to the bottom plate is transmitted to the beam as it is, it disappears by the dispersion to the pillar and the vibration of the beam itself as described above. Of course, it will be designed with full account of the anticipated impact that the deck and beam building will receive.

그런데, 축조된 건축물에 예상 충격 이상의 충격이 가해지거나, 예상 충격 이내라도 지속적인 충격을 받게 되면, 보 또는 바닥판이 부분적으로 파손되거나 내구성을 상실하여 결국에는 건축물의 안정된 구조가 망가지는 심각한 사태를 초래할 수도 있다.However, if the built structure is subjected to more than the expected impact or sustained impact even within the expected impact, the beam or floor plate may be partially damaged or lose its durability, which may eventually lead to serious damage to the stable structure of the building. have.

종래에는 이러한 문제를 해소하기 위해 도 1(종래 TMD의 설치모습을 도시한 단면도)에 도시한 바와 같은 TMD(Tuned Mass Damper) 공법이 적용되었다.Conventionally, the TMD (Tuned Mass Damper) method has been applied to solve this problem, as shown in Fig. 1 (a cross-sectional view showing the installation of a conventional TMD).

TMD는 바닥판 또는 보(이하 "바닥판(10)"이라 한다.)에 상호 나란히 고정되는 한 쌍의 제1,2지지대(21, 22)와, 양단이 제1,2지지대(21, 22)에 각각 고정되어서 충격을 받은 바닥판(10)의 자체 진동에 대응해 진동하는 감쇠판(23)으로 구성된다.The TMD is a pair of first and second supports 21 and 22 fixed side by side to the bottom plate or beam (hereinafter referred to as "bottom plate 10"), and both ends of the first and second supports 21 and 22. It is composed of a damping plate 23 which is fixed to the oscillation and vibrates in response to its own vibration of the bottom plate 10 is shocked.

이러한 구조를 갖는 TMD는 바닥판(10)이 충격을 받아 진동하면, 제1,2지지대(21, 22)를 매개로 바닥판(10)과 직접 연결된 감쇠판(23)에 그 충격이 전달되면서 감쇠판(23)을 진동시키되, 감쇠판(23)의 진동상태는 바닥판(10)의 진동상태와 불규칙적으로 상쇄 또는 보강되면서 바닥판(10)이 받는 충격을 감쇠시키는 것이다([표 1] 참고). 참고로, 도 1에 도시된 제1,2지지대(21, 22)는 제1지지대(21)와 제2지지대(22)가 각각 독립된 물품을 보이지만, 제1,2지지대(21, 22)가 'ㄷ' 형상의 양단부를 각각 이루는 일체일 수도 있다. When the TMD having such a structure vibrates under impact of the bottom plate 10, the impact is transmitted to the damping plate 23 directly connected to the bottom plate 10 through the first and second supports 21 and 22. While vibrating the damping plate 23, the vibration state of the damping plate 23 is to attenuate the shock received by the bottom plate 10 while being canceled or reinforced irregularly with the vibration state of the bottom plate 10 (Table 1). Reference). For reference, the first and second supports 21 and 22 shown in FIG. 1 show an article in which the first support 21 and the second support 22 are independent, respectively, but the first and second supports 21 and 22 are It may be an integral part of each end of the 'c' shape.

그런데, TMD는 바닥판(10) 진동의 감쇠 효율을 높이기 위해서, 설치될 해당 바닥판(10)의 설계에 맞춰 감쇠판(23)의 두께와 길이 등에 대한 규격을 결정해야 한다. 즉, 동일한 건축물이라 하더라도 어느 바닥판(10)에 설치되는 것이냐에 따라 TMD의 규격을 달리 제작해야 하는 것이다.By the way, in order to increase the damping efficiency of the vibration of the bottom plate 10, the TMD should determine the specification of the thickness and length of the damping plate 23 according to the design of the bottom plate 10 to be installed. In other words, even if the same building to be installed on which floor plate 10 is to be made different TMD specifications.

하지만, 건축물에 대량으로 설치 적용되는 TMD를 설치위치와 대상에 따라 모두 다른 모습으로 제작 및 생산한다는 것은 경제적으로나 건축물의 시공 효율면에 있어서 매우 불리한 것이다. 물론, 이러한 불리함은 건축비의 증가를 초래하므로 이에 대한 해결책이 시급히 요구되는 상황이었다. However, manufacturing and producing TMDs that are applied in large quantities to buildings in different shapes depending on the installation location and objects is economically disadvantageous in terms of construction efficiency. Of course, this disadvantage caused an increase in construction costs, so a solution was urgently required.

또한, 건축물이 노후하면 건축 자재의 성질변화로 인해 건축물의 강도와 무게 정도가 변하게 된다. 하지만, 초기 설계에 맞게 적용된 TMD는 성질이 변화된 건축물에 적절치 못하게 되면서 TMD의 기능을 충분히 발휘하지 못하게 된다. In addition, the aging of the building changes the strength and weight of the building due to the change in the properties of the building material. However, the TMD applied to the initial design is not appropriate for the buildings whose properties have changed, and thus the TMD does not fully function.

이와 더불어, 보다 안정되고 견고한 건축물을 설계 및 조성하고, 건축 자재의 성질변화에도 최상의 완충 및 내진환경을 조성할 수 있는 더 발전된 완충 및 내진공법이 요구되고 있었다.In addition, more advanced shock absorbing and vacuum methods are required to design and construct more stable and robust buildings, and to create the best shock and seismic environment for changing the properties of building materials.

이에 본 발명은 상기와 같은 문제를 해소하기 위해 안출된 것으로, 충격에 의한 바닥판의 진동을 단시간 내에 감쇠시켜서 건축물 전체가 받는 부담을 줄일 수 있고, 균일한 형태와 규격으로 양산하면서도 다양한 위치에 융통성 있게 적용 및 설치할 수 있는 자기유변 감쇠기와 감쇠판을 이용한 바닥판 구조물의 진동 제어장치의 제공을 기술적 과제로 한다.Accordingly, the present invention has been made to solve the above problems, by reducing the vibration of the floor plate due to the impact in a short time to reduce the burden on the whole building, and mass production in a uniform form and standard, yet flexible in various locations It is a technical task to provide a vibration control device of a bottom plate structure using a magnetorheological attenuator and a damper plate that can be applied and installed in a convenient manner.

Therefore, it is possible to reduce the construction cost and improve the stability of the building.

이하 본 발명을 첨부된 예시도면에 의거하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 진동 제어장치의 설치모습을 도시한 단면도인 바, 이를 참조하여 설명한다.Figure 2 is a cross-sectional view showing an installation of the vibration control device according to the present invention, will be described with reference to this.

본 발명에 따른 진동 제어장치(30)는 바닥판(10)에 고정되는 제1,2지지대(31, 32)와, 제1,2지지대(31, 32)에 양단이 각각 고정되는 감쇠판(33)과, 감쇠판(33)과 바닥판(10) 간을 완충하는 자기유변 감쇠기(34)를 포함한다.Vibration control device 30 according to the present invention is the first and second support (31, 32) fixed to the bottom plate 10, the damping plate is fixed to both ends of the first and second support (31, 32) ( 33, and a magnetorheological attenuator 34 which buffers the damping plate 33 and the bottom plate 10.

여기서, 제1,2지지대(31, 32)는 [배경기술]에서 설명한 바와 같이, 일체로 된 'ㄷ' 형상일 수도 있으므로, 이하에서는 제1,2지지대(31, 32)를 지지대(31, 32)로 기술한다.Here, since the first and second supports 31 and 32 may have an integrated 'c' shape as described in the Background Art, the first and second supports 31 and 32 will be referred to as the support 31, 32).

전술한 바와 같이, 바닥판(10)이 충격으로 진동하면, 지지대(31, 32)를 매개로 바닥판(10)과 나란히 이격 배치된 감쇠판(33)도 진동하는데, 자기유변 감쇠기(34)는 바닥판(10)과 감쇠판(33)을 유동적으로 연결하면서도 바닥판(10)의 진동과 감쇠판(33)의 진동을 서로 상쇄시킨다. 물론, 바닥판(10)은 감쇠판(33) 자체의 진동 형태와 상쇄된 진동 형태를 보이면서 진동이 안정된다.As described above, when the bottom plate 10 vibrates by impact, the damping plate 33 spaced apart from the base plate 10 along the support plates 31 and 32 also vibrates, and the magnetorheological damper 34 The fluid cancels the vibration of the bottom plate 10 and the vibration of the damping plate 33 while fluidly connecting the bottom plate 10 and the damping plate 33. Of course, the bottom plate 10 is stable vibration while showing the vibration form canceled with the vibration form of the damping plate 33 itself.

여기서, 자기유변 감쇠기(34)는 일반적인 뎀퍼의 실린더(341; 도 3 참조)에 자기유변유체(Magnetorheological Fluid)를 주입한 것으로, 자기유변유체는 자기장 내에서 점성이 높아지는 성질을 갖는 물질이다.Here, the magnetorheological attenuator 34 is a magnetorheological fluid injected into a cylinder 341 (see FIG. 3) of a general damper. The magnetorheological fluid is a material having a property of increasing viscosity in a magnetic field.

널리 알려진 바와 같이, 자기유변유체는 오일과 나노사이즈의 도전성 분말을 혼합해서, 비 자기장 내에서는 오일의 특성을 보이고, 자기장 내에서는 정렬되는 도전성 분말에 의해 점성이 증가한 겔 또는 고체의 특성을 보이도록 된 것이다. 일반적으로 자기유변 감쇠기(34)는 자기장을 선택적으로 형성시키기 위해서, 영구자석이 아닌 전자석이 적용될 것이다.As is well known, magnetorheological fluids mix oils and nano-sized conductive powders to show the properties of oils in non-magnetic fields and to increase the viscosity of gels or solids by the conductive powders aligned in magnetic fields. It is. In general, the magnetorheological attenuator 34 may use an electromagnet instead of a permanent magnet to selectively form a magnetic field.

이상 설명한 바와 같이, 본 발명에 따른 진동 제어장치(30)는 동일한 유동성을 갖는 일반적인 유체를 대신해서 자기유변유체를 이용해 자기유변 감쇠기(34)의 완충기능을 조정하여, 동일한 규격의 지지대(31, 32) 및 감쇠판(33)으로도 바닥판(10)의 특성에 맞는 적절한 진동제어를 이룰 수 있는 것이다.As described above, the vibration control device 30 according to the present invention adjusts the shock absorbing function of the magnetorheological damper 34 by using a magnetorheological fluid in place of a general fluid having the same fluidity, thereby supporting the support 31 of the same standard. 32) and the damping plate 33 can achieve an appropriate vibration control according to the characteristics of the bottom plate (10).

도 3은 본 발명에 따른 진동 제어장치에 구성된 자기유변 감쇠기와 컨트롤러의 통신구조를 도시한 도면인 바, 이를 참조하여 설명한다.FIG. 3 is a diagram illustrating a communication structure of a magnetorheological attenuator and a controller configured in the vibration control apparatus according to the present invention.

전술한 바와 같이, 자기유변 감쇠기(34)는 서로 격실되되 협소한 통로(341c)를 통해 연통되고 자기유변유체(344)가 충진되는 제1,2실(341a, 341b)로 된 실린더(341)와, 제1,2실(341a, 341b)에 각각 삽입되고 바닥판(10)과 감쇠판(33)에 말단이 각각 제1,2체결수단(342a, 342b)을 매개로 고정되는 제1,2가압피스톤(342, 343)으로 된다.As described above, the magnetorheological attenuators 34 are cylinders 341 of first and second chambers 341a and 341b which are enclosed with each other but communicate through narrow passages 341c and are filled with the magnetorheological fluid 344. First and second inserts respectively inserted into the first and second chambers 341a and 341b and fixed to the bottom plate 10 and the damping plate 33 by means of the first and second fastening means 342a and 342b, respectively. It becomes two pressure pistons 342 and 343.

한편, 진동 제어장치(30)는 자기유변 감쇠기(34)를 제어하는 제어모듈(35)을 더 포함한다.On the other hand, the vibration control device 30 further includes a control module 35 for controlling the magnetorheological attenuator 34.

제어모듈(35)은 실린더(341)에 충진된 자기유변유체(344)에 자기장을 가해서 자기유변 감쇠기(34)가 갖는 감쇠력을 조정하는 것으로, 자기유변유체(344)에 직접 자기장을 형성시키는 제어수단(351)과, 제어수단(351)의 처리상태와 조작을 제어하 는 입력수단(352)을 포함하고, 필요에 따라 자기유변유체(344)의 상태 또는 관리자가 입력수단(352)을 조작해 입력한 값을 출력하는 출력수단(353)을 더 포함할 수 있다.The control module 35 adjusts the damping force of the magnetorheological attenuator 34 by applying a magnetic field to the magnetorheological fluid 344 filled in the cylinder 341, thereby forming a magnetic field directly on the magnetorheological fluid 344. Means 351, and input means 352 for controlling the processing state and operation of the control means 351, the state of the magnetorheological fluid 344 or an administrator operating the input means 352 as necessary. It may further include an output means 353 for outputting the input value.

제어수단(351)은 자기장 형성이 유리한 코일 등을 매개로 실린더(341)와 전기적으로 연결되고, 바닥판(10)의 진동상태와 감쇠판(33)의 진동상태를 감지하는 센서(미도시함)의 신호를 수신해서 자기유변유체(344)의 점성변화 정도를 연산하며, 코일에 적당한 크기의 전류를 흘려 실린더(341) 내에 자기장을 조성함으로서, 자기유변유체(344)의 점성을 조정한다.The control means 351 is electrically connected to the cylinder 341 via a coil or the like, in which magnetic field formation is advantageous, and a sensor for detecting a vibration state of the bottom plate 10 and a vibration state of the damping plate 33 (not shown). The viscosity of the magnetorheological fluid 344 is calculated by calculating the degree of viscosity change of the magnetorheological fluid 344, and the viscosity of the magnetorheological fluid 344 is adjusted by creating a magnetic field in the cylinder 341 by flowing a current having a moderate magnitude through the coil.

참고로, 상기 센서는 바닥판의 진동상태를 지속적으로 감지하면서 이를 제어수단(351)으로 전송하는 것으로, 센서가 감지하는 데이터는 바닥판의 진동주기 및 진동응답(가속도, 속도, 변위) 등이 될 것이다. For reference, the sensor continuously detects a vibration state of the bottom plate and transmits it to the control means 351. The data detected by the sensor includes a vibration period and a vibration response (acceleration, speed, displacement) of the bottom plate. Will be.

[표 1]은 일반 바닥판과, 종래 TMD가 설치된 바닥판과, 본 발명에 따른 진동 제어장치가 설치된 바닥판에 대한 진동 변화상태를 보인 그래프이다.[Table 1] is a graph showing the vibration change state for the general floor plate, the bottom plate is a conventional TMD is installed, and the bottom plate is installed vibration control apparatus according to the present invention.

여기서, w/o TMD는 진동제어를 하지 않은 바닥판 구조물의 가속도 응답을 보인 것이고(종래1), w/ TMD는 종래 수동진동제어 장치(TMD)를 적용한 경우의 가속도 응답을 보인 것이며(종래2), w/ STMD는 본 발명에 따른 진동 제어장치(30)를 적용한 경우의 가속도 응답을 보인 것이다.Here, w / o TMD is the acceleration response of the base plate structure without vibration control (priority 1), w / TMD is the acceleration response when the conventional passive vibration control device (TMD) is applied (conventional 2) ), w / STMD shows the acceleration response when the vibration control device 30 according to the present invention is applied.

[표 1]에서 보이는 바와 같이, 종래1은 최초 충격시 바닥판(10)의 진폭이 증가하면서 진동량이 커짐을 알 수 있고, 종래2는 최초 충격시 바닥판(20)의 진폭이 점차 작아짐을 알 수 있다. 그런데, 본 발명에 따른 진동 제어장치(30)를 적용한 경우, 최초 충격시 바닥판(10)의 진폭이 단시간 내로 작아지면서 상쇄율이 종래1과는 물론 종래2의 경우와도 충분히 대비됨을 확인할 수 있다.As shown in Table 1, the conventional art 1 shows that the vibration amount increases as the amplitude of the bottom plate 10 increases during the first impact, and the conventional 2 shows that the amplitude of the bottom plate 20 gradually decreases during the initial impact. Able to know. However, when the vibration control device 30 according to the present invention is applied, the amplitude of the bottom plate 10 is reduced within a short time at the time of the first impact, and the offset rate is sufficiently contrasted with that of the conventional 1 as well as the conventional 2. have.
