Description

철도차량의 바닥구조{RAILWAY FLOOR STRUCTURE}Floor structure of railway vehicle {RAILWAY FLOOR STRUCTURE}

본 고안은 승객용 철도차량의 바닥구조에 관한 것으로, 철도차량 바닥의 금속판재(SUS 혹은 Al 압출재)와 합판 사이에 현재 사용하는 고무 대신, 점접촉 2종 재질 적층 지지구조를 사용하여 면적 및 재질의 급격한 변화에 따른 구조간의 임피던스 변화를 크게 하여 철도차량 바닥에서 올라오는 진동의 전파를 최소화하여 승객의 승차감을 향상시키고자 한다.    The present invention relates to a floor structure of a passenger railroad vehicle, and instead of the rubber currently used between the metal plate (SUS or Al extruded material) of the railroad floor, instead of the rubber currently used, the area and material by using the point contact two-layer laminated support structure By increasing the impedance change between structures due to the rapid change of, to minimize the propagation of the vibration from the floor of the railway vehicle to improve the passenger comfort.

일반적으로 철도차량의 바닥구조는 차량 하부의 충격 및 진동을 흡수하는 역활을 한다. 도 3에서 도시한 바와 같이 기존 바닥구조물은 합판지지부의 배치가 선접촉이며, 지지부는 1종 재질로 구성되어 있다.In general, the floor structure of the railway vehicle serves to absorb the shock and vibration of the lower portion of the vehicle. As shown in FIG. 3, the existing floor structure has a plywood support portion arranged in line contact, and the support portion is made of one kind of material.

기존 합판지지부는 1종 재질로 구성되어 재질의 특성에 따라 충격 및 진동 흡수량의 크기가 달라지며, 합판과 바닥부(금속판재) 사이의 접합 시, 특수 양면테입을 사용함으로서 합판과 바닥부의 평활도에 따라 접촉 면적이 상이하게 되어 정량적 진동 흡수량을 예측하는데 한계가 있고, 이에 따른 방진설계가 어렵게 된다. 이에 본 고안은 상기와 같은 문제점을 해결하기 위하여 도 1과 같이 합판지지부 배치를 선접촉이 아닌 점접촉으로 하여 금속판재와 합판 사이의 임피던스 변화를 증대시키며, 도 2와 같이 합판과 바닥부의 평활도와 관계없이 정확한 체결을 위하여 볼트체결을 한다. 또한 도 2의 2-2와 2-3과 같이 2 종 재질을 사용하여 재질에 따른 진동 임피던스 효과도 증대시킨다.  Existing plywood support part is composed of one kind of material, and the magnitude of shock and vibration absorption varies depending on the characteristics of the material. Therefore, the contact area is different, there is a limit in predicting the quantitative vibration absorption amount, it is difficult to design the dust. Therefore, the present invention increases the impedance change between the metal plate and the plywood by making the plywood support part arrangement as point contact rather than line contact as shown in FIG. 1 to solve the above problems, and as shown in FIG. Regardless, fasten bolts for correct tightening. In addition, the use of two kinds of materials, such as 2-2 and 2-3 of Figure 2 also increases the vibration impedance effect according to the material.

상기와 같은 목적을 위하여 본 고안은 철도차량의 바닥구조에 관한 것으로, 차량 바닥의 바닥부(금속판재) 위에 현재 사용하는 고무의 배치방법(선접촉)을 따르지 않고 2종 재질 적층 점접촉 지지구조를 통한 면적 및 재질 진동 임피던스 효과에 따른 진동절연 효과를 높이며, 차량의 중량 감소효과가 있는 철도차량의 바닥구조에 관한 것이다.  For this purpose, the present invention relates to a floor structure of a railroad car, and does not follow the current method of arranging rubber (line contact) on a floor (metal plate) of the floor of a vehicle, and is a two-layer laminated point contact support structure. The present invention relates to a floor structure of a railway vehicle, which increases the vibration insulation effect according to the area and material vibration impedance effects through the weight reduction effect of the vehicle.

상기 설명한 바와 같이 본 고안은 점접촉에 따른 진동전달 면적을 줄임에 따라 바닥재의 흡진효과를 높이며, 바닥재의 하중을 줄인다. 또한 2 종 재질로 구성된 합판지지부는 1 종 재질로 구성된 지지부에 비하여, 다층재질에 따른 진동임피던스 효과로 흡진효과가 나타난다. 볼트체결은 바닥부, 합판지지부, 합판 사이 연결을 명확하게 하며, 이에 따른 설계자의 진동절연효과 예측 및 설계에 도움을 줄 수 있다.  As described above, the present invention increases the absorption effect of the flooring material by reducing the vibration transmission area due to the point contact, and reduces the load of the flooring material. In addition, the plywood support part composed of two kinds of materials exhibits a dust-absorbing effect due to the vibration impedance effect according to the multilayer material, compared to the support part composed of one kind of materials. The bolting clarifies the connection between the bottom, plywood support and plywood, which can help the designer predict and design the vibration insulation effect.

본 고안을 첨부된 도면에 의거하여 상세히 설명한다. 도 1을 참조하면, 바닥부(1)와 합판(3) 사이에 합판지지부(2)를 이격되도록 배치하여, 또한, 바닥부(1)와 합판(3)이 합판지지부(3)에 의해 점접촉되도록 설치한다.
도 2를 참조하면, 합판지지부(2)와 바닥부(1) 간의 체결과 합판지지부(2)와 합판(3) 간의 체결은 볼트로 체결로 한다.
여기서, 합판지지부(2)와 합판(3)과의 체결 시에는 합판(3)의 변형에 따른 연결부 파손을 고려하여 2개의 볼트로 체결하고, 합판지지부(2)와 바닥부(1)와의 체결 시에는 조립성을 감안하여 1개의 볼트로 체결한다.
한편, 합판지지부(2)는 제1방진고무(2-2)와 제2방진고무(2-3)을 교대로 적층되도록 형성하여 적어도 2층으로 적층한다. 도시된 바는 제2방진고무(2-3)를 사이에 두고 상하로 제1방진고무(2-2)가 적층형성된 것이 도시되어 있다.
여기서, 상기 제1방진고무(2-2)는 볼트체결이 가능한 강도를 갖는 방진고무이고, 상기 제2방진고무(2-3)는 진동절연 효과를 갖는 연성이 높은 방진고무이다. 이러한 구조물을 통하여 다층 철도차량 바닥구조를 구성한다.
The present invention will be described in detail with reference to the accompanying drawings. Referring to FIG. 1, the plywood support part 2 is arranged to be spaced apart between the bottom part 1 and the plywood 3, and the bottom part 1 and the plywood 3 are pointed by the plywood support part 3. Install in contact.
2, the fastening between the plywood support 2 and the bottom 1 and the fastening between the plywood support 2 and the plywood 3 are fastened by bolts.
Here, when the plywood support 2 and the plywood 3 are fastened with two bolts in consideration of damage to the connection part due to deformation of the plywood 3, the plywood support 2 and the bottom 1 are fastened. In case of assembly, tighten with one bolt.
On the other hand, the plywood support portion 2 is formed so as to alternately stack the first anti-vibration rubber (2-2) and the second anti-vibration rubber (2-3) to be laminated in at least two layers. As shown in the drawing, the first anti-vibration rubber 2-2 is stacked up and down with the second anti-vibration rubber 2-3 interposed therebetween.
Here, the first anti-vibration rubber 2-2 is an anti-vibration rubber having a strength capable of fastening the bolt, the second anti-vibration rubber (2-3) is a high ductile anti-vibration rubber having a vibration insulating effect. Through such a structure, a multi-layer railway vehicle floor structure is constructed.
