Description

나선형 구조의 금속자재 부산물을 활용한 방진소재Anti-vibration material using spiral structure metal by-products
본 발명의 실시예들은 방진소재에 관한 것으로, 더욱 상세하게는 금속자재 제작가공 단계에서 발생하는 부산물을 재활용한 나선형 구조의 방진체와 고무패드를 이용하여 소음진동을 저감시키기 위한 나선형 구조의 금속자재 부산물을 활용한 방진소재에 관한 것이다.Embodiments of the present invention relate to a vibration-proof material, and more particularly, a spiral-structured metal material for reducing noise and vibration by using a spiral structure vibration isolator and a rubber pad recycled by-products generated in the metal material manufacturing and processing step. It relates to a dustproof material using by-products.
종래의 방진 기술들은 성능은 우수하지만, 단점은 크게 2가지로 친환경적 소재가 아니라는 것과 수명이 길지 않다는 점이다. Conventional anti-vibration technologies have excellent performance, but there are two major drawbacks: they are not eco-friendly materials and their lifespan is not long.
더 뛰어난 성능을 나타내기 위해서 다양한 소재를 사용하긴 하지만, 친환경적인 소재가 아닐뿐더러 비싼 소재를 사용하기도 하고 무게 또한 무거울 수 있다. Although various materials are used to show superior performance, it is not an eco-friendly material, and it uses expensive materials and may be heavy.
또한, 사용 초기에는 성능이 우수하지만 시간이 지나면서 공기 중의 수분이 마운트 내부로 침투하거나 마운트 내부에 있는 휘발성 물질들이 공기 중으로 날아가 부식되거나 연성이 떨어지게 되고 부스러기처럼 갈라져버리는 현상이 일어나고 초기의 기계적 성능을 나타내기 어려워진다.In addition, the performance is excellent at the beginning of use, but over time, moisture in the air penetrates into the inside of the mount, or volatile substances inside the mount fly into the air, causing corrosion or deterioration of ductility and cracking like crumbs. It becomes difficult to show
한편, 와이어형식의 마운트는 성능이 뛰어나고 스테인리스 소재를 이용하였기 때문에 수명은 매우 길고 마찰댐퍼를 이용하여 아주 좋은 성능을 낼 수 있다.On the other hand, the wire-type mount has excellent performance and because it uses a stainless steel material, it has a very long lifespan and can achieve very good performance by using a friction damper.
하지만 와이어로프 형태로 만들기 위해 추가적인 제작 공정이 필요하고 와이어 자체를 생산하기 위해서는 많은 공정과정을 거쳐야 하며 따라서 단가가 매우 비싸다는 단점이 있다.However, there is a disadvantage that an additional manufacturing process is required to make the wire rope form, and many processes are required to produce the wire itself, and thus the unit price is very expensive.
관련 선행기술로는, 대한민국 등록특허공보 제10-1806016호가 있다.As a related prior art, there is Korean Patent Registration No. 10-1806016.

Specifically, in the present invention, a plurality of vibration isolators may be implemented using by-products of metal materials.
다수의 방진체는 다수의 배열을 이루며 길이 방향을 따라 나선형으로 구현될 수 있다.The plurality of vibration isolators may be formed in a plurality of arrangements and spirally formed along the longitudinal direction.
일 실시예로, 다수의 방진체는 도 1에 도시된 바와 같이 동일한 길이를 가지는 방진체가 일 방향을 따라 나란하게 배열될 수 있다. 그러나, 이에 한정되지 않고, 다수의 방진체는 서로 다른 길이를 가지는 방진체가 교차되게 배열되는 등의 다양한 배열을 이룰 수 있다.In one embodiment, as shown in FIG. 1 , a plurality of vibration isolators may be arranged side by side in one direction with the vibration isolators having the same length. However, the present invention is not limited thereto, and the plurality of vibration isolators may be arranged in various arrangements, such as the vibration isolators having different lengths are arranged to cross each other.
다수의 방진체는 소정의 길이를 가지며 길이 방향을 따라 나선형의 헬릭스(helix) 구조로 구현될 수 있다. 구체적으로, 다수의 방진체는 건축용 강재, 선박용 강재 등의 산업용 강재 제작 시, 회전체 드릴을 사용하여 모따기, 구멍뚫기 등의 가공단계에서 발생하는 꽈배기 형상의 나선형 구조를 가지는 부산물로 구현될 수 있다.The plurality of vibration isolators may have a predetermined length and may be implemented in a spiral helix structure along the longitudinal direction. Specifically, a plurality of vibration isolators is a by-product having a twist-shaped spiral structure that occurs in the processing steps such as chamfering and hole drilling using a rotating body drill when manufacturing industrial steel materials such as steel for construction and steel for ships. It can be implemented as a by-product. .
다수의 방진체는 각 배열의 길이방향을 따라 서로 포개어지는 구조를 가질 수 있다. The plurality of vibration isolators may have a structure overlapping each other along the longitudinal direction of each arrangement.
즉, 일 방향을 따라 나란하게 배열되는 각각의 방진체는 양측 또는 일측으로 포개어지는 면이 서로 접촉되도록 구현될 수 있다.That is, each of the vibration isolators arranged side by side in one direction may be implemented such that the surfaces overlapped on both sides or one side are in contact with each other.
예컨대, 배열의 내측에 위치하는 방진체는 양측에 인접한 타 방진체와 서로 겹쳐질 수 있으며, 배열의 외측 즉, 가장자리에 위치하는 방진체는 일측에 인접한 타 방진체와 서로 겹쳐질 수 있다.For example, the vibration isolators located inside the array may overlap other vibration isolators adjacent to both sides, and the vibration isolators located outside the array, that is, at the edge, may overlap with the other vibration isolators adjacent to one side.
일 실시예로, 다수의 방진체는 하기 수학식 1에 의해 서로 포개어지는 구조를 가질 수 있다.In one embodiment, the plurality of vibration isolators may have a structure that is superimposed on each other by Equation 1 below.
[수학식 1][Equation 1]
0 < d <= r0 < d <= r
여기서, d는 방진체가 포개어지는 면적에 대한 길이, r은 방진체의 수직단면을 기준으로 중심부에서 둘레면까지의 거리를 의미함.Here, d is the length of the overlapping area of the vibration isolator, and r is the distance from the center to the peripheral surface based on the vertical section of the vibration isolator.
수학식 1에 의하면, 서로 인접한 두 방진체가 포개어짐에 따라 겹쳐지는 부분에 대한 면적의 길이(d)를 기준으로 방진체의 진동 저감 효과를 구현할 수 있다.According to Equation 1, the vibration reduction effect of the vibration isolator can be implemented based on the length (d) of the area of the overlapping part as the two adjacent vibration isolators are overlapped.
예컨대, 도 4a를 참조하면, 상기 면적의 길이(d)가 0의 값보다 크고 방진체의 수직단면을 기준으로 중심부에서 둘레면까지의 거리보다는 작은 경우에 해당한다.For example, referring to FIG. 4A , it corresponds to a case in which the length d of the area is greater than a value of 0 and smaller than the distance from the center to the circumferential surface based on the vertical section of the vibration isolator.
일 실시예로, 다수의 방진체는 하기 수학식 2에 의해 서로 포개어지는 구조를 가질 수 있다.In one embodiment, the plurality of vibration isolators may have a structure in which they are superimposed on each other according to Equation 2 below.
[수학식 2][Equation 2]
d = rd = r
여기서, d는 방진체가 포개어지는 면적에 대한 길이, r은 방진체의 수직단면을 기준으로 중심부에서 둘레면까지의 거리를 의미함.Here, d is the length of the overlapping area of the vibration isolator, and r is the distance from the center to the peripheral surface based on the vertical section of the vibration isolator.
수학식 2에 의하면, 서로 인접한 두 방진체가 포개어짐에 따라 겹쳐지는 부분에 대한 면적의 길이(d)를 기준으로 방진체의 진동 저감 효과를 구현할 수 있다.According to Equation 2, as the two adjacent vibration isolators are superimposed, the vibration reduction effect of the vibration isolator can be realized based on the length (d) of the area of the overlapping part.
예컨대, 도 4b를 참조하면, 상기 면적의 길이(d)가 방진체의 수직단면을 기준으로 중심부에서 둘레면까지의 거리(r)와 동일한 경우에 해당한다. 이러한 경우, 포개어지는 방진체 간의 마찰력이 고조되어 진동 저감 효과를 극대화시킬 수 있다.For example, referring to FIG. 4B , it corresponds to the case where the length d of the area is equal to the distance r from the center to the circumferential surface with respect to the vertical section of the vibration isolator. In this case, the frictional force between the overlapping vibration isolators is heightened, so that the vibration reduction effect can be maximized.
한편, 상기 면적의 길이(d)가 방진체의 수직단면을 기준으로 중심부에서 둘레면까지의 거리(r) 보다 커지는 경우, 방진체 간 결속력이 커지게 되어 마찰력이 저하됨에 따라 진동 저감 효과가 감소될 수 있다.On the other hand, when the length (d) of the area is greater than the distance (r) from the center to the circumferential surface based on the vertical section of the vibration isolator, the binding force between the vibration isolators increases and the frictional force decreases, thereby reducing the vibration reduction effect. can be
다수의 방진체는 각 배열 간의 마찰로 인해 진동원으로부터 발생되는 진동을 저감시킬 수 있다.A plurality of vibration isolators can reduce vibrations generated from vibration sources due to friction between the respective arrays.
고무패드는 다수의 방진체의 양면 중 적어도 일면과 결합될 수 있다.The rubber pad may be coupled to at least one of both surfaces of the plurality of vibration isolators.
예컨대, 고무패드는 도 1에 도시된 바와 같이 다수의 방진체의 일면과 결합될 수 있고, 도 5에 도시된 바와 같이 다수의 방진체의 양면과 모두 결합될 수 있다.For example, the rubber pad may be combined with one surface of the plurality of vibration isolators as shown in FIG. 1 , and may be combined with both surfaces of the plurality of vibration isolators as shown in FIG. 5 .
이로 인해, 고무패드가 다수의 방진체를 일측 또는 양측에서 지지해줌으로써, 방진체들을 효과적으로 결속하되 방진체 간 마찰이 상호 간 잘 전달되도록 할 수 있다.For this reason, the rubber pad supports the plurality of vibration isolators from one side or both sides, effectively binding the vibration isolators, but allowing the friction between the vibration isolators to be transmitted well to each other.
일 실시예로, 고무패드의 두께가 커질수록 저감되는 진동의 주파수는 높아질 수 있다. 이에 따라, 다수의 방진체의 두께를 기준으로 고무패드의 두께를 상대적으로 작게 구현하여 진동의 주파수 대역을 낮추는 것이 바람직하다.In one embodiment, as the thickness of the rubber pad increases, the frequency of the reduced vibration may increase. Accordingly, it is preferable to reduce the frequency band of vibration by implementing a relatively small thickness of the rubber pad based on the thickness of the plurality of vibration isolators.
참고로, 고무패드는 스티로폼, 우레탄 등의 재료로 구현될 수 있으며, 바닥단열을 위해 사용되는 기포가 포함된 기포 콘크리트, 경량의 콘크리트 등의 재료와 복합하여 구현될 수도 있다.For reference, the rubber pad may be implemented with a material such as styrofoam or urethane, and may be implemented by combining with a material such as foamed concrete or lightweight concrete used for floor insulation.
도 6을 참조하면, 다수의 방진체는 복층의 형태로 적층될 수 있다.Referring to FIG. 6 , a plurality of vibration isolators may be stacked in the form of multiple layers.
즉, 다수의 방진체의 양면에 고무패드가 결합되어 샌드위치 구조의 방진 마운트를 구현할 수 있다. That is, rubber pads are combined on both sides of a plurality of vibration isolators to implement a vibration protection mount of a sandwich structure.
이러한 경우, 다수의 방진체가 적층되는 층의 개수가 많아질수록 상기 저감되는 진동의 주파수는 낮아질 수 있다. 다시 말해, 단층으로 구현된 방진 마운트의 경우보다 복층으로 구현된 방진 마운트에 포함된 방진체들의 두께가 커져 저주파수 대역의 진동을 저감시키는데 효과를 발휘할 수 있다.In this case, as the number of layers on which a plurality of vibration isolators are stacked increases, the frequency of the reduced vibration may be lowered. In other words, since the thickness of the vibration isolators included in the vibration protection mount implemented in multiple layers is greater than in the case of the vibration mount implemented in a single layer, it can be effective in reducing vibration in a low frequency band.
일 실시예로, 다수의 방진체는 각 층마다 동일한 방향을 향하도록 평행한 배열을 이룰 수 있다.In an embodiment, the plurality of vibration isolators may be arranged in parallel to face the same direction for each layer.
다른 실시예로, 다수의 방진체는 각 층마다 서로 상이한 방향을 향하도록 불규칙한 배열을 이룰 수 있다. 다시 말해, 다수의 방진체는 각 층마다 서로 교차하는 방향, 랜덤의 방향 등으로 불규칙하게 배열되거나, 불규칙하게 겹쳐져 적층될 수 있다.In another embodiment, the plurality of vibration isolators may be arranged irregularly to face different directions for each layer. In other words, the plurality of vibration isolators may be arranged irregularly in a direction crossing each other for each layer, a random direction, or the like, or may be irregularly overlapped and stacked.
본 실시예에서, 다수의 방진체는 불규칙한 배열을 이루는 경우에 비해 평행한 배열을 이루는 경우에 보다 방진체 간 마찰이 크게 일어나 진동 저감 성능이 커질 수 있다.In the present embodiment, the friction between the vibration isolators is greater when the plurality of vibration isolators are arranged in parallel than when the plurality of vibration isolators are arranged in an irregular arrangement, so that the vibration reduction performance can be increased.
이로써, 본 발명의 실시예들에 따르면, 다수의 배열을 이루며 서로 포개어지도록 형성되는 나선형의 방진체를 구현함에 따라, 보다 낮은 주파수의 진동을 저감시킬 수 있어 회전기계나 충격성 진동에 매우 높은 저항성을 가질 수 있다.Accordingly, according to embodiments of the present invention, by implementing a spiral vibration isolator formed to be overlapped with each other in a plurality of arrangements, it is possible to reduce vibrations of lower frequencies, and thus very high resistance to rotating machines or impact vibrations. can have
뿐만 아니라, 본 발명의 실시예들에 따르면, 공작기계의 가공으로 인한 산업 생산과정에서 발생되는 금속자재의 부산물을 활용하여 방진체를 구현함으로써, 친환경적인 소재를 사용함에 따른 단가 절감 및 수명 연장에 효과적일 수 있다.In addition, according to the embodiments of the present invention, by implementing a vibration isolator by utilizing the by-product of the metal material generated in the industrial production process due to the processing of the machine tool, it is possible to reduce the unit cost and extend the lifespan by using an eco-friendly material. It can be effective.
도 7a는 본 발명의 방진소재가 사용된 방진 마운트와 일반산업용 방진 마운트의 전달함수를 비교하기 위한 그래프이고, 도 7b는 도 7a의 일반산업용 방진 마운트를 나타낸 도면이다.Figure 7a is a graph for comparing the transfer function of the anti-vibration mount and the general industrial anti-vibration mount using the dust-proof material of the present invention, Figure 7b is a view showing the general industrial anti-vibration mount of Figure 7a.
도 7a는 검은색 마운트, 노란색 마운트, 하늘색 마운트, 흰색 마운트에 해당하는 일반산업용 방진 마운트와 한쪽 고무판 및 양쪽 고무판을 각각 사용하여 구현된 본 발명의 나선형 구조를 가지는 방진소재에 대하여 진동이 전달될 때 나타나는 진동 저감 정도를 전달함수에 대해 주파수 별로 나타낸 그래프이다. Figure 7a shows a black mount, a yellow mount, a light blue mount, and a general industrial anti-vibration mount corresponding to a white mount, and when vibration is transmitted to the anti-vibration material having a spiral structure of the present invention implemented using one rubber plate and both rubber plates, respectively. It is a graph showing the degree of vibration reduction that appears for each frequency with respect to the transfer function.
도 7a를 참조하면, 일반산업용 방진 마운트에 비해 본 발명의 방진 마운트의 경우 보다 낮은 주파수 대역에서 저감 성능이 나타나는 것을 알 수 있다.Referring to Figure 7a, it can be seen that the reduction performance appears in a lower frequency band than in the case of the anti-vibration mount of the present invention compared to the general-purpose anti-vibration mount.
구체적으로, 일반산업용 방진 마운트는 100 내지 200 Hz 범위에서 피크값이 나타남에 따라 상대적으로 높은 주파수 영역에서 저감 성능이 나타나는 반면에, 본 발명의 방진 마운트는 100 Hz 이하의 범위에서 피크값이 나타남에 따라 상대적으로 낮은 주파수 영역에서 저감 성능이 나타나는 것을 확인할 수 있다.Specifically, the general industrial anti-vibration mount shows a reduction performance in a relatively high frequency region as a peak value appears in the range of 100 to 200 Hz, whereas the anti-vibration mount of the present invention shows a peak value in the range of 100 Hz or less. Accordingly, it can be confirmed that the reduction performance appears in a relatively low frequency region.
한편, 본 발명의 경우, 한쪽 고무판을 사용한 경우보다 양쪽 고무판을 사용한 경우에 더 낮은 피크값을 나타내고 있어 저주파수 대역에서의 저감 성능이 훨씬 뛰어남을 알 수 있다.On the other hand, in the case of the present invention, it can be seen that a lower peak value is shown when both rubber plates are used than when one rubber plate is used, so that the reduction performance in the low frequency band is much superior.
도 8은 본 발명의 일 실시예에 있어서, 방진소재의 적층 및 배열 형태에 따른 진동저감 성능을 비교하기 위한 그래프이다.8 is a graph for comparing vibration reduction performance according to the stacking and arrangement of vibration-proof materials in an embodiment of the present invention.
도 8은 본 발명의 방진소재를 단층으로 구현한 샘플(단층 Chip)과 복층으로 구현하되 방진체의 층 간 배열을 격자 배열로 구현한 샘플(복층 Chip, Grid 배열)과 복층으로 구현하되 방진체의 층 간 배열을 평행한 배열로 구현한 샘플(복층 Chip, 평행 배열)에 대해 나타나는 진동 저감 정도를 전달함수에 대해 주파수 별로 나타낸 그래프이다.8 is a sample (single-layer chip) implemented as a single layer of the vibration-proof material of the present invention and a multi-layered sample (multi-layered chip, grid array) and a multi-layered sample in which the interlayer arrangement of the vibration isolator is implemented as a lattice array It is a graph showing the degree of vibration reduction for a sample (multi-layer chip, parallel array) in which the interlayer arrangement of is implemented as a parallel arrangement for each frequency with respect to the transfer function.
도 8을 참조하면, 단층으로 구현한 샘플에 비해 복층으로 구현한 샘플의 경우, 방진체의 두께가 커짐에 따라 저감되는 진동의 주파수 범위가 감소하는 것을 알 수 있다. 또한, 복층으로 구현한 샘플 중에서 격자 배열로 구현한 샘플에 비해 평행한 배열로 구현한 샘플의 경우, 저주파수 대역에서의 피크값이 낮게 나타남에 따라 저감 성능이 훨씬 뛰어남을 확인할 수 있다.Referring to FIG. 8 , it can be seen that in the case of a sample implemented as a multi-layer compared to a sample implemented as a single layer, the frequency range of the reduced vibration decreases as the thickness of the vibration isolator increases. In addition, in the case of a sample implemented in a parallel arrangement compared to a sample implemented in a lattice arrangement among samples implemented as multiple layers, it can be confirmed that the reduction performance is much better as the peak value in the low frequency band is lower.
