Japanese Patent Laid-Open No. 7-17398

ところで、鉄道車両の構体には更なる軽量化が要請されている。また、軽量化を図りつつも、負荷に対する変形の少ない鉄道車両の構体が要請されている。   By the way, further weight reduction is required for the structure of a railway vehicle. Further, there is a demand for a structure of a railway vehicle that is light in weight and has little deformation with respect to a load.

そこで、本発明は、軽量且つ負荷に対する変形の少ない鉄道車両の構体を提供することを目的としている。   Therefore, an object of the present invention is to provide a railway vehicle structure that is lightweight and has little deformation with respect to a load.

本願の発明者は、鋭意研究を重ねた結果、中梁がなくとも、枕梁に加わる力を、枕梁及び側梁を介して分散させることができるという知見を得た。かかる知見に基づく本発明の鉄道車両の構体は、以下の通り構成されている。   As a result of intensive studies, the inventor of the present application has obtained the knowledge that the force applied to the pillow beam can be dispersed through the pillow beam and the side beam even without the intermediate beam. The structure of the railway vehicle of the present invention based on such knowledge is configured as follows.

即ち、本発明の鉄道車両の構体は、連節型の鉄道車両の構体であって、台枠と、側構体とを備えている。側構体は、外板を有しており、台枠に接続されている。台枠は、一対の枕梁と、横梁と、一対の側梁とを有している。一対の枕梁は、鉄道車両の幅方向に延びている。横梁は、一対の枕梁の間において上記幅方向に延びている。一対の側梁は、台枠の幅方向における両側において鉄道車両の長手方向に延びている。この台枠においては、上記長手方向に延びる部材のうち、一対の側梁のみが、一対の枕梁及び横梁の全てに接続している。側構体には、上記長手方向における一方側と他方側に一対の第１の開口が設けられており、該一対の第１の開口の間に一以上の第２の開口が設けられている。   That is, the structure of the railway vehicle of the present invention is an articulated railway vehicle structure, and includes a frame and a side structure. The side structure has an outer plate and is connected to the underframe. The underframe has a pair of pillow beams, a horizontal beam, and a pair of side beams. The pair of pillow beams extends in the width direction of the railway vehicle. The horizontal beam extends in the width direction between the pair of pillow beams. The pair of side beams extends in the longitudinal direction of the railway vehicle on both sides in the width direction of the underframe. In this frame, only a pair of side beams among the members extending in the longitudinal direction are connected to all of the pair of pillow beams and the cross beams. The side structure is provided with a pair of first openings on one side and the other side in the longitudinal direction, and one or more second openings are provided between the pair of first openings.

本発明の鉄道車両の構体においては、第１の開口の下側の外板の厚さは、第２の開口の下側の外板の厚さより厚くなっていることが好適である。または、本発明の鉄道車両の構体においては、第１の開口の下側の外板に、上下方向に延びる梁が結合されていることが好適である。或いは、本発明の鉄道車両の構体においては、第１の開口の下側の外板の厚さは、第２の開口の下側の外板の厚さより厚くなっており、更に、第１の開口の下側の外板に、上下方向に延びる梁が結合されていることが好適である。   In the structure of the railway vehicle according to the present invention, it is preferable that the thickness of the lower outer plate of the first opening is larger than the thickness of the lower outer plate of the second opening. Alternatively, in the structure of the railway vehicle according to the present invention, it is preferable that a beam extending in the vertical direction is coupled to the lower outer plate of the first opening. Alternatively, in the structure of the railway vehicle of the present invention, the thickness of the lower outer plate of the first opening is greater than the thickness of the lower outer plate of the second opening. It is preferable that a beam extending in the vertical direction is coupled to a lower outer plate of the opening.

本発明の鉄道車両の構体には中梁が設けられていない。したがって、鉄道車両の構体の軽量化が、実現されている。また、第１の開口の下側の部分には、他の部分に比して大きな荷重が加わるが、板厚の調整又は／及び梁の導入によって、第１の開口の下側の部分の強度が、第２の開口の下側の部分の強度より高められている。したがって、本発明の鉄道車両の構体では、軽量化への影響を抑えつつ、側構体及び台枠の変形が低減されている。

The structure of the railway vehicle according to the present invention is not provided with a middle beam. Therefore, the weight reduction of the structure of the railway vehicle is realized. In addition, a large load is applied to the lower portion of the first opening as compared to the other portions. However, the strength of the lower portion of the first opening is adjusted by adjusting the plate thickness or / and introducing the beam. Is higher than the strength of the lower portion of the second opening. Therefore, in the structure of the railway vehicle of the present invention, the deformation of the side structure and the underframe is reduced while suppressing the influence on weight reduction.

また、本発明の鉄道車両の構体においては、第１の開口の下側の外板に、上下方向に延びる梁が結合されていることが好適である。当該梁によれば、側構体の強度が、更に向上され、延いては台枠の変形が更に低減される。   In the railway vehicle structure of the present invention, it is preferable that a beam extending in the vertical direction is coupled to the lower outer plate of the first opening. According to the beam, the strength of the side structure is further improved, and the deformation of the underframe is further reduced.

また、本発明の鉄道車両の構体においては、一対の側梁それぞれと枕梁とに結合された補強部材を更に備えることが好適である。当該結合部材によれば、枕梁と側梁とに加わる応力を低減することが可能である。   In the railway vehicle structure of the present invention, it is preferable to further include a reinforcing member coupled to each of the pair of side beams and the pillow beam. According to the coupling member, it is possible to reduce the stress applied to the pillow beam and the side beam.

本発明によれば、軽量且つ負荷に対する変形の少ない鉄道車両の構体が提供される。   ADVANTAGE OF THE INVENTION According to this invention, the structure of a railway vehicle with a light weight and little deformation | transformation with respect to a load is provided.

以下、図面を参照して本発明の好適な実施形態について詳細に説明する。なお、各図面において同一又は相当の部分に対しては同一の符号を附すこととする。   DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

図１は、本発明の実施の形態に係る鉄道車両の構体を概略的に示す斜視図である。なお、本願においては、図１に示す状態を基準に方向を示す用語を用いる。即ち、長手方向とは鉄道車両の進行方向と同方向であり、幅方向とは長手方向に直交する方向である。また、台枠に対して屋根構体が位置する方向が上であり、屋根構体に対して台枠が位置する方向が下である。   FIG. 1 is a perspective view schematically showing a structure of a railway vehicle according to an embodiment of the present invention. In the present application, terms indicating directions are used with reference to the state shown in FIG. That is, the longitudinal direction is the same direction as the traveling direction of the railway vehicle, and the width direction is a direction orthogonal to the longitudinal direction. In addition, the direction in which the roof structure is positioned with respect to the frame is on the top, and the direction in which the frame is positioned with respect to the roof structure is on the bottom.

図１に示す鉄道車両の構体１０は、一対の妻構体１２、屋根構体１４、台枠１６、及び一対の側構体１８を備えている。   A railcar structure 10 shown in FIG. 1 includes a pair of end structures 12, a roof structure 14, a frame 16, and a pair of side structures 18.

妻構体１２、屋根構体１４、台枠１６、及び側構体１８は、相互に接続されている。一対の妻構体１２は、鉄道車両の長手方向における一端及び他端に設けられている。屋根構体１４は、構体１０における屋根を構成しており、上記の長手方向に延びている。   The wife structure 12, the roof structure 14, the underframe 16, and the side structure 18 are connected to each other. The pair of wife structures 12 are provided at one end and the other end in the longitudinal direction of the railway vehicle. The roof structure 14 constitutes a roof in the structure 10 and extends in the longitudinal direction.

台枠１６は、構体１０における床部を構成しており、床板（図示せず）を支持している。図２は、本発明の実施の形態に係る台枠を示す平面図である。図２は、台枠を上側から見た状態を示している。図２に示すように、台枠１６は、一対の枕梁１６ａと、複数の横梁１６ｂと、一対の側梁１６ｃとを有している。台枠１６は、例えば、幅２７６６ｍｍ、厚さ１５０ｍｍであり、且つ、構体１０の長手方向の全体にわたるサイズを有している。   The underframe 16 constitutes a floor portion in the structure 10 and supports a floor board (not shown). FIG. 2 is a plan view showing a frame according to the embodiment of the present invention. FIG. 2 shows a state in which the underframe is viewed from above. As shown in FIG. 2, the underframe 16 has a pair of pillow beams 16a, a plurality of transverse beams 16b, and a pair of side beams 16c. The frame 16 has, for example, a width of 2766 mm, a thickness of 150 mm, and a size over the entire length of the structure 10.

一対の枕梁１６ａは、台枠１６における長手方向の一端及び他端に設けられている。枕梁１６ａは、台枠１６の幅方向に延在している。枕梁１６ａは、例えば、台枠１６の長手方向に５４０ｍｍの長さを有している。枕梁１６ａには、例えば、内部に補強用のリブ板が設けられた厚板の溶接組立体が用いられる。   The pair of pillow beams 16 a is provided at one end and the other end in the longitudinal direction of the underframe 16. The pillow beam 16 a extends in the width direction of the underframe 16. The pillow beam 16a has, for example, a length of 540 mm in the longitudinal direction of the underframe 16. For the pillow beam 16a, for example, a thick plate welding assembly in which a reinforcing rib plate is provided is used.

一対の枕梁１６ａの間には、複数の横梁１６ｂが設けられている。複数の横梁１６ｂは、台枠１６の幅方向に延在している。   A plurality of transverse beams 16b are provided between the pair of pillow beams 16a. The plurality of horizontal beams 16 b extend in the width direction of the frame 16.

一対の側梁１６ｃは、台枠１６の幅方向の両側に設けられており、台枠１６の長手方向に延在している。   The pair of side beams 16 c are provided on both sides in the width direction of the frame 16 and extend in the longitudinal direction of the frame 16.

一対の側梁１６ｃには、一対の枕梁１６ａ及び複数の横梁１６ｂが、例えば溶接によって結合されている。すなわち、この構体１０の台枠１６においては、長手方向に延びる部材のうち、一対の枕梁１６ａ及び複数の横梁１６ｂの全てに結合されている部材が、一対の側梁１６ｃのみになっている。   A pair of pillow beams 16a and a plurality of cross beams 16b are joined to the pair of side beams 16c by, for example, welding. That is, in the underframe 16 of this structure 10, among the members extending in the longitudinal direction, the members coupled to all of the pair of pillow beams 16a and the plurality of lateral beams 16b are only the pair of side beams 16c. .

また、台枠１６では、側梁１６ｃと枕梁１６ａとによって形成される四隅に、補強部材１６ｄが設けられている。補強部材１６ｄは、側梁１６ｃと枕梁１６ａに結合されている。これら補強部材１６ｄには、例えば、厚さ９ｍｍ、且つ、１００ｍｍ×２００ｍｍの直交する辺を有する直角三角形の平面形状の部材を用いることができる。   In the underframe 16, reinforcing members 16d are provided at the four corners formed by the side beams 16c and the pillow beams 16a. The reinforcing member 16d is coupled to the side beam 16c and the pillow beam 16a. As these reinforcing members 16d, for example, right-angled triangular planar members having a thickness of 9 mm and orthogonal sides of 100 mm × 200 mm can be used.

再び図１を参照する。図１に示すように、構体１０における幅方向の両側には、一対の側構体１８が設けられている。側構体１８は、構体１０の側面を構成しており、長手方向に延在している。   Refer to FIG. 1 again. As shown in FIG. 1, a pair of side structures 18 are provided on both sides of the structure 10 in the width direction. The side structure 18 constitutes a side surface of the structure 10 and extends in the longitudinal direction.

側構体１８には、二つの第１の開口１８ａが、長手方向の一方側及び他方側に設けられている。また、側構体１８には、第１の開口１８ａの間に二つの第２の開口１８ｂが設けられている。本実施の形態では、第１の開口１８ａ及び第２の開口１８ｂは、構体１０における窓用の開口とされている。また、これらの開口の間には、三つの第３の開口１８ｃが設けられている。本実施の形態では、第３の開口１８ｃは、構体１０における出入口用の開口とされている。   The side structure 18 is provided with two first openings 18a on one side and the other side in the longitudinal direction. The side structure 18 is provided with two second openings 18b between the first openings 18a. In the present embodiment, the first opening 18 a and the second opening 18 b are window openings in the structure 10. In addition, three third openings 18c are provided between these openings. In the present embodiment, the third opening 18 c is an entrance / exit opening in the structure 10.

以下、側構体１８の更に詳細な構造について説明する。図３は、第１の開口１８ａ近傍の側構体１８を、車内側から見て示す平面図である。なお、図３には、一方側の第１の開口１８ａ近傍の側構体１８の平面図が示されているが、他方側の第１の開口１８ａ近傍の側構体１８の構造は、図３に示すものと略対称な構造である。   Hereinafter, a more detailed structure of the side structure 18 will be described. FIG. 3 is a plan view showing the side structure 18 in the vicinity of the first opening 18a as viewed from the inside of the vehicle. 3 shows a plan view of the side structure 18 near the first opening 18a on one side, the structure of the side structure 18 near the first opening 18a on the other side is shown in FIG. The structure is substantially symmetrical to that shown.

図３に示すように、第１の開口１８ａは、略矩形の開口が設けられた窓フレーム１８ｄによって画成されている。この窓フレーム１８ｄの上下方向に延びる周縁には、一対の梁１８ｅが、溶接等によって結合されている。一対の梁１８ｅは、側構体１８の上端から下端まで延びている。   As shown in FIG. 3, the first opening 18a is defined by a window frame 18d provided with a substantially rectangular opening. A pair of beams 18e is joined to the peripheral edge extending in the vertical direction of the window frame 18d by welding or the like. The pair of beams 18 e extends from the upper end to the lower end of the side structure 18.

また、窓フレーム１８ｄの上下の周縁には、一対の梁１８ｆが、溶接等によって結合されている。これらの梁１８ｆ及び梁１８ｅは、側構体１８の外板にも結合されている。   A pair of beams 18f are joined to the upper and lower peripheral edges of the window frame 18d by welding or the like. These beams 18 f and 18 e are also coupled to the outer plate of the side structure 18.

側構体１８の外板は、複数の区画に分割されており、第１の開口１８ａの下側の外板１８ｇの厚さが、側構体１８における他の外板より厚くなっている。すなわち、第１の開口１８ａの下側の外板１８ｇの厚さが、第２の開口１８ｂの下側の外板１８ｈ（図１を参照）より、厚くなっている。なお、例えば、外板１８ｇの厚さは２．５ｍｍであり、外板１８ｈの厚さは１．５ｍｍである。   The outer plate of the side structure 18 is divided into a plurality of sections, and the thickness of the outer plate 18 g below the first opening 18 a is thicker than the other outer plates in the side structure 18. That is, the thickness of the outer plate 18g on the lower side of the first opening 18a is thicker than the outer plate 18h on the lower side of the second opening 18b (see FIG. 1). For example, the thickness of the outer plate 18g is 2.5 mm, and the thickness of the outer plate 18h is 1.5 mm.

この外板１８ｇには、更に、上下方向に延びる梁１８ｉが、溶接等によって結合されている。梁１８ｉの上端は、第１の開口１８ａの下側の梁１８ｆに結合されている。   A beam 18i extending in the vertical direction is further coupled to the outer plate 18g by welding or the like. The upper end of the beam 18i is coupled to the lower beam 18f of the first opening 18a.

以下、構体１０の作用及び効果について説明する。上述したように、台枠１６において長手方向に延びる部材のうち側梁１６ｃのみが、枕梁１６ａと横梁１６ｂの全てに結合されている。即ち、台枠１６は、従来の鉄道車両の構体と異なり、中梁を有していない。したがって、台枠１６は、従来の鉄道車両の構体における台枠より軽量である。   Hereinafter, the operation and effect of the structure 10 will be described. As described above, only the side beams 16c among the members extending in the longitudinal direction in the frame 16 are coupled to all the pillow beams 16a and the horizontal beams 16b. That is, the underframe 16 does not have a middle beam unlike a conventional railway vehicle structure. Therefore, the underframe 16 is lighter than the underframe in the conventional railway vehicle structure.

また、本実施の形態の側構体１８では、当該側構体１８に設けられている開口のうち車端に最も近い第１の開口１８ａの下側の外板１８ｇの厚さが、外板１８ｈ等の他の部分の外板の厚さより厚くなっている。即ち、第１の開口１８ａの下側の外板１８ｇの厚さのみが、厚くなっている。また、外板１８ｇには、更に、上下方向に延びる梁１８ｉが、溶接等によって結合されており、外板１８ｈには、同様の梁が設けられていない。これによって、構体１０の軽量化への影響を抑えつつ、側構体１８の強度が高められている。なお、上述したように、台枠１６に中梁が設けられていないので、枕梁１６ａに加えられて側梁１６ｃを介して側構体１８に伝わる力は、従来の鉄道車両の構体に比べて大きくなる。しかしながら、構体１０では、側構体１８の強度が高められているので、側構体１８の変形、延いては台枠１６の変形が低減される。   Further, in the side structure 18 of the present embodiment, the thickness of the outer plate 18g below the first opening 18a closest to the vehicle end among the openings provided in the side structure 18 is equal to the outer plate 18h or the like. It is thicker than the thickness of the outer plate of other parts. That is, only the thickness of the outer plate 18g on the lower side of the first opening 18a is thick. Further, a beam 18i extending in the vertical direction is further coupled to the outer plate 18g by welding or the like, and a similar beam is not provided on the outer plate 18h. Thus, the strength of the side structure 18 is increased while suppressing the influence on the weight reduction of the structure 10. As described above, since the frame 16 is not provided with the intermediate beam, the force applied to the pillow beam 16a and transmitted to the side structure 18 via the side beam 16c is larger than that of the conventional structure of a railway vehicle. growing. However, in the structure 10, since the strength of the side structure 18 is increased, the deformation of the side structure 18, and further the deformation of the frame 16 is reduced.

また、略直角をなして結合された枕梁１６ａと側梁１６ｃとによって形成される四隅に補強部材１６ｄが設けられている。かかる補強部材１６ｄによれば、枕梁１６ａと側梁１６ｃとの結合部における応力が低減される。   Reinforcing members 16d are provided at the four corners formed by the pillow beams 16a and the side beams 16c joined at a substantially right angle. According to the reinforcing member 16d, the stress at the joint between the pillow beam 16a and the side beam 16c is reduced.

以下、構体１０の変形に関するＦＥＭ（FiniteElement Method）解析の結果について説明する。この解析結果は、枕梁に連結器からの圧縮荷重４９００００Ｎを加え、且つ車両垂直方向の荷重要素１１００００Ｎを加えた場合の台枠上の床面の変位を求めたものである。   Hereinafter, the result of the FEM (Finite Element Method) analysis regarding the deformation of the structure 10 will be described. This analysis result is obtained by calculating the displacement of the floor surface on the underframe when the compressive load 490000N from the coupler is applied to the pillow beam and the load element 110000N in the vehicle vertical direction is applied.

図４は、構体１０の実施例の変形に関する解析結果を示す図である。実施例には、上述した数値例の構体１０をモデル化したものを用いた。また、図５は、比較例の変形に関する解析結果を示す図である。比較例に係る構体には、枕梁から４本目の横梁までに２本の中梁（長さ２７１３．５ｍｍ）が結合されている点を除いて、構体１０の実施例と同様の構成の構体をモデル化したものを用いた。   FIG. 4 is a diagram illustrating an analysis result regarding deformation of the structure 10 according to the embodiment. In the embodiment, a modeled structure 10 of the numerical example described above was used. FIG. 5 is a diagram illustrating an analysis result regarding the deformation of the comparative example. The structure according to the comparative example has the same structure as that of the structure 10 except that two middle beams (length: 2713.5 mm) are coupled from the pillow beam to the fourth horizontal beam. The model of was used.

図４及び図５において、横軸は台枠の端部からの長手方向の距離を示しており、縦軸は台枠の床面における各位置の変位を示している。また、図４及び図５においては、側梁上の床面における各位置の変位が実線で示されており、中梁上の床面における各位置の変位が点線で示されており、車幅中央の床面における各位置の変位が一点鎖線で示されている。なお、図４に示す中梁上の床面の各位置とは、比較例における中梁上の床面の各位置に対応する実施例の床面上の各位置である。   4 and 5, the horizontal axis indicates the distance in the longitudinal direction from the end of the frame, and the vertical axis indicates the displacement of each position on the floor surface of the frame. 4 and 5, the displacement at each position on the floor surface on the side beam is indicated by a solid line, and the displacement at each position on the floor surface on the middle beam is indicated by a dotted line. The displacement at each position on the center floor is indicated by a one-dot chain line. In addition, each position of the floor surface on the middle beam shown in FIG. 4 is each position on the floor surface of the example corresponding to each position of the floor surface on the middle beam in the comparative example.

図５を参照する。比較例の構体は、十分な長さの中梁を有しており、図５に示すように、その台枠の各位置の変位の絶対値は３ｍｍ以下である。これに対して、実施例の台枠には、中梁が設けられていないが、図４に示すように、台枠における各位置の変位の絶対値は、３ｍｍ以下と小さい。すなわち、この解析結果から、中梁をなくすことによって３０ｋｇの軽量化が図られており、且つ変形が少ない構体を提供可能であることが確認できる。   Please refer to FIG. The structure of the comparative example has a sufficiently long middle beam, and as shown in FIG. 5, the absolute value of the displacement at each position of the underframe is 3 mm or less. In contrast, the frame of the embodiment is not provided with a middle beam, but as shown in FIG. 4, the absolute value of the displacement at each position in the frame is as small as 3 mm or less. That is, from this analysis result, it can be confirmed that the weight of 30 kg can be reduced by eliminating the intermediate beam and a structure with little deformation can be provided.
