스마트 하이브리드 댐퍼Smart hybrid damper
본 발명은 스마트 하이브리드 댐퍼에 관한 것으로서, 보다 상세하게는 진동의 종류에 따라 변위의 제어를 달리하도록 함으로써 효과적인 감쇠력을 제공하도록 하는 스마트 하이브리드 댐퍼에 관한 것이다.The present invention relates to a smart hybrid damper, and more particularly, to a smart hybrid damper to provide an effective damping force by varying the control of displacement according to the type of vibration.
일반적으로, 건물, 교량, 철도, 기반 시설 등의 구조물은 기능성 및 안정성을 향상 및 확보하도록 시공되는데, 많은 엔지니어와 건축가들은 지진으로부터 구조물을 안전하게 보호할 수 있는 방안들을 강구하고 있다.In general, structures such as buildings, bridges, railways, and infrastructures are constructed to improve and secure functionality and stability. Many engineers and architects are looking for ways to safely protect structures from earthquakes.
이러한 내진 구조물에 있어서, 구조물에 가해지는 지진에너지를 소산시키는 장치로서 댐퍼가 널리 사용되고 있는데, 이러한 댐퍼는 구조물의 구조부재, 예컨대 브레이스(brace)에 연결되어 구조부재에 작용하는 응력 및 변위를 저감시키도록 한다.In such an earthquake-resistant structure, a damper is widely used as a device for dissipating seismic energy applied to the structure, and the damper is connected to a structural member of the structure, such as a brace, to reduce stress and displacement acting on the structural member. To do.
그러나, 종래의 구조물용 댐퍼는 지진에너지의 소산 작용에 대한 신뢰성을 확보하는데 한계를 가지고 있으며, 제작 및 조립이 어려울 뿐만 아니라, 고가로 인해 경제적인 구조물의 시공을 어렵게 하는 문제점을 가지고 있었다.However, the conventional damper for structures has limitations in securing reliability for the dissipation action of seismic energy, and it is difficult to manufacture and assemble, and has a problem that it is difficult to construct an economical structure due to high cost.
이러한 문제점을 해소하기 위하여, 종래 기술로서, 한국공개특허 제10-2013-0092694호의 "구조물용 댐퍼"가 제시된 바 있는데, 이는 구조물에 설치되는 댐퍼에 있어서, 케이스; 상기 케이스 내에 탄소성을 이용하여 진동에너지를 소산시키도록 다수로 나란하게 장착되되, 다수 중 일부가 상기 케이스의 일단으로 돌출됨과 아울러 나머지가 상기 케이스의 타단으로 돌출되며, 각각의 돌출되는 부분에 상기 구조물의 구조부재에 연결되기 위한 연결부가 각각 마련되는 코어; 및 상기 코어 사이에 위치하도록 상기 케이스 내에 설치되어 상기 코어의 좌굴을 방지하도록 하는 채움부재;를 포함한다. In order to solve this problem, as a conventional technique, there has been proposed a "damper for structures" of Korean Patent Publication No. 10-2013-0092694, which includes a case for a damper installed in a structure; The casing is mounted side by side in a plurality to dissipate vibrational energy by using the carbon property, some of which protrude to one end of the case, and the rest protrude to the other end of the case, and each protruding part is A core provided with connecting parts for connecting to structural members of the structure; And a filling member installed in the case to be positioned between the cores to prevent buckling of the cores.
이러한 종래 기술은 지진에너지의 소산 작용에 대한 신뢰성을 높이도록 하고, 제작 및 조립이 용이한 구조를 가질 수 있으며, 이로 인해 경제성을 도모할 수 있도록 하는 장점을 가진다.

그러나, 종래 기술은 지진에너지의 소산 작용을 높이기 위하여 마찰력을 제대로 이용하는데 한계를 가지고, 감쇠력을 용이하게 조절하지 못하는 문제점을 가지고 있었다. 또한, 종래 기술은 진동의 종류에 따라 효과적인 감쇠력을 발휘하도록 하는 기술적 구성이 제시되어 있지 않아, 외부 충격 등으로부터 구조물을 안정적으로 보호하는데 한계를 가지는 문제점을 가지고 있었다.However, the prior art has a limitation in properly using the frictional force to enhance the dissipation action of seismic energy, and has a problem in that it is not easy to control the damping force. In addition, in the prior art, a technical configuration has not been proposed to exert an effective damping force according to the type of vibration, and thus has a problem in that the structure is stably protected from external impacts.
상기한 바와 같은 종래 기술의 문제점을 해결하기 위하여, 본 발명은 마찰력 및 점성력을 이용한 댐핑에 의해 뛰어난 댐핑 작용을 가질 뿐만 아니라, 지진에너지의 소산 작용이 뛰어나도록 하고, 제작 및 조립이 용이한 구조를 제공하며, 필요에 따라 감쇠력의 조절을 위해 마찰력을 쉽게 조절할 수 있을 뿐만 아니라, 진동의 종류에 따라 효과적인 감쇠력을 발휘하도록 함으로써 구조물의 안정화 유지에 크게 도움을 주도록 하는데 목적이 있다.

점성댐핑부(400)는 제 1 및 제 2 슬라이더(210,220) 중 다른 하나와 제 2 연결부재(120) 중 어느 하나에 연결되는 제 1 피스톤로드(410)가 실린더(300)의 일측에 관통하도록 설치되고, 제 1 피스톤로드(410)에 고정되는 제 1 헤드(420)가 실린더(300) 내에서 유체, 즉 점성유체의 통과를 허용하도록 슬라이딩 가능하게 고정되며, 제 1 헤드(420)의 양측에 제 1 피스톤로드(410)가 기밀되게 슬라이딩 가능하도록 제 1 차단부재(430)가 각각 설치되고, 제 1 차단부재(430) 사이의 제 1 댐핑공간(440)에 점성유체(450)가 채워진다. 여기서, 점성유체(450)는 예컨대 실리콘오일일 수 있다. 또한, 제 1 헤드(420)는 왕복 이동시 점성유체(450)의 통과를 허용하도록, 본 실시례에서처럼 실린더(300)의 내측면과의 사이에 유격을 가지도록 형성되거나, 다른 예로서 오리피스가 관통하도록 형성될 수 있다.The viscous damping part 400 is such that the first piston rod 410 connected to any one of the first and second sliders 210 and 220 and the second connecting member 120 penetrates one side of the cylinder 300. The first head 420, which is installed and fixed to the first piston rod 410, is slidably fixed to allow passage of a fluid, that is, a viscous fluid, in the cylinder 300, and both sides of the first head 420 A first blocking member 430 is respectively installed so that the first piston rod 410 can be slidably sealed, and the first damping space 440 between the first blocking members 430 is filled with a viscous fluid 450. . Here, the viscous fluid 450 may be, for example, silicone oil. In addition, the first head 420 is formed to have a clearance between the inner surface of the cylinder 300, as in this embodiment, to allow the passage of the viscous fluid 450 during reciprocating movement, or through an orifice as another example Can be formed.
점성댐핑부(400)는 실린더(300)로부터 돌출되는 제 1 피스톤로드(410)의 끝단에 제 1 커버(460)가 실린더(300)의 끝단에 슬라이딩 가능하도록 결합될 수 있다. 따라서, 제 1 피스톤로드(410)의 노출을 최소화하여, 외부 구성부재와의 접촉 등으로 인한 간섭을 방지하고, 내구성 향상에 기여할 수 있다.The viscous damping unit 400 may be coupled such that the first cover 460 is slidable to the end of the cylinder 300 at the end of the first piston rod 410 protruding from the cylinder 300. Therefore, the exposure of the first piston rod 410 is minimized to prevent interference due to contact with external components, etc., and to contribute to improved durability.
고점성댐핑부(500)는 제 1 및 제 2 슬라이더(210,220) 중 다른 하나와 제 2 연결부재(120) 중 다른 하나에 연결되는 제 2 피스톤로드(510)가 실린더(300)의 타측에 관통하도록 설치되고, 제 2 피스톤로드(510)에 고정되는 제 2 헤드(520)가 실린더(300) 내에서 유체, 즉 고점성유체의 통과를 허용하도록 슬라이딩 가능하게 고정되며, 제 2 헤드(520)의 양측에 제 2 피스톤로드(510)가 기밀되게 슬라이딩 가능하도록 제 2 차단부재(530)가 각각 설치되고, 제 2 차단부재(530) 사이의 제 2 댐핑공간(540)에 충격 하중 발생시 유체에서 탄성 고체로의 변화로 인해 변위 발생을 제어하는 고점성유체(550)가 채워진다. 여기서, 고점성유체는 급격한 진동 발생시 록킹(locking)이 되는 구속 장치로서의 역할을 수행하는데, 예컨대 고점성 실리콘 유체로서, 일례로 실리콘 퍼티(Silicon putty)로 이루어질 수 있다. 또한, 제 2 헤드(520)는 왕복 이동시 고점성유체(550)의 통과를 허용하도록, 본 실시례에서처럼 실린더(300)의 내측면과의 사이에 유격을 가지도록 형성되거나, 다른 예로서 오리피스가 관통하도록 형성될 수 있다.The high-viscosity damping part 500 has a second piston rod 510 connected to the other of the first and second sliders 210 and 220 and the other of the second connecting members 120 penetrates the other side of the cylinder 300. The second head 520 is installed so as to be fixed to the second piston rod 510, is slidably fixed to allow the passage of a fluid, that is, a high-viscosity fluid, in the cylinder 300, and the second head 520 A second blocking member 530 is installed on both sides of the second piston rod 510 to be slidably sealed, and in the fluid when an impact load is generated in the second damping space 540 between the second blocking members 530 Due to the change to the elastic solid, the high-viscosity fluid 550 that controls displacement occurrence is filled. Here, the high-viscosity fluid serves as a restraining device that is locked when sudden vibration occurs, for example, as a high-viscosity silicon fluid, for example, it may be made of silicone putty. In addition, the second head 520 is formed to have a clearance between the inner surface of the cylinder 300, as in this embodiment, to allow the passage of the high-viscosity fluid 550 during reciprocating movement, or as an example orifice It can be formed to penetrate.
고점성댐핑부(500)는 실린더(300)로부터 돌출되는 제 2 피스톤로드(510)의 끝단에 제 2 커버(560)가 실린더(300)의 끝단에 슬라이딩 가능하도록 결합될 수 있다. 따라서, 제 2 피스톤로드(510)의 노출을 최소화하여, 외부 구성부재와의 접촉 등으로 인한 간섭을 방지하고, 내구성 향상에 기여할 수 있다. 또한 고점성댐핑부(600)는 제 2 댐핑공간(540)의 길이가 제 1 댐핑공간(440)의 길이에 대하여 20~70%일 수 있다. 여기서 제 2 댐핑공간(540)의 길이가 제 1 댐핑공간(440)의 길이에 대하여 20% 미만인 경우, 고점성댐핑부(600)가 원하는 스트로크를 확보하지 못하는 문제점이 발생하게 되고, 70% 초과인 경우 비경제적일 뿐만 아니라, 컴팩트한 구조의 제공이 어렵게 되는 문제점을 가지게 된다. The high-viscosity damping part 500 may be coupled to the second end of the second piston rod 510 protruding from the cylinder 300 so that the second cover 560 is slidable to the end of the cylinder 300. Therefore, the exposure of the second piston rod 510 is minimized to prevent interference due to contact with external components, etc., and to contribute to improvement of durability. In addition, the high-viscosity damping unit 600 may have a length of the second damping space 540 of 20 to 70% relative to the length of the first damping space 440. Here, when the length of the second damping space 540 is less than 20% with respect to the length of the first damping space 440, a problem occurs that the high-viscosity damping part 600 cannot secure a desired stroke, and exceeds 70% In this case, it is not only economical, but also has a problem in that it is difficult to provide a compact structure.
