【発明の属する技術分野】
本発明は、リニア車両等の鉄道車両の車体と台車の間等の隙間や段差を無くして平滑化することにより、空気抵抗・空力音を低減するために車体と台車間等に取り付けられるフェアリングに関するものである。
【0002】
【従来の技術】
リニア車両に代表される、最近の鉄道車両は高速化が進み車体の構造は航空機の構造に類似する。鉄道車両と航空機の違いは、鉄道車両は車輪または超伝導磁石を備えた台車を有し、軌道に沿って走行する必要があることである。 走行する軌道は直線だけではなく、カーブ、上下の勾配、直線・カーブ・勾配の組み合わせ等、軌道の変化があり、そのような軌道変化に合わせて変位する台車と車体間の空間部分が、高速走行時において空気抵抗となり、また、その空間において空気の乱れを起こし騒音を発生するという問題があった。
【0003】
従って、従来からもこの点に対処するために車体と台車間の隙間や段差を無くして平滑化することを目的としたフェアリングが提供されている。例えば、図3に示す如く、車体B、C間の変位に対応するように、台車と車体間の空間に数枚の擦り合せ板で伸縮可能に構成されたフェアリング部材Dを取付金具で取り付けるフェアリングの構成が提案されている(特許文献1 参照。)。
【0004】
【特許文献1】
実開平7−40344号公報(図4)
【0005】
【発明が解決しようとする課題】
しかしながら、このフェアリングは車両の走行方向が一定の向きである場合は格別問題はないが、走行方向が逆の方向になった場合は板を重ね合せた隙間に空気が入り、高速の流体による動圧によって破損するおそれがあった。また、この動圧に耐えるように隙間の密着強度を向上させた場合、その強度のために台車の動く抵抗が大きくなりすぎて軌道の変化に追随出来ず、また乗り心地が悪化するという問題が生じる。
【0006】
そこで、この発明の目的とするところは、車体と台車間の空間を閉鎖し、隙間や段差を無くして平滑化することにより空気抵抗・空力音を低減するフェアリングにおいて、車両の走行方向に拘らず空気抵抗・空力音の低減を達成し得るとともに、耐久性を有するフェアリングを提供するところにある。
【0007】
【課題を解決するための手段】
上記目的を達成するため、本発明においてはそれ自体で伸縮性を有するフェアリング部材を開発し、このフェアリング部材を取付部材を介して車体と台車間に取り付けることにより、上記問題点を解消したものである。
【0008】
すなわち、本発明のフェアリングは、リニア車両等の鉄道車両の車体と台車の間の隙間や段差を無くして平滑化するフェアリングにおいて、外側シート、内側シート並びに両シート間に配された高分子合成スポンジ体からなり、外側シート及び内側シートは縦方向に低伸度、横方向に高伸度の異方弾性性能をもつ編物等の異方弾性シート材で構成され、外側シートと内側シートを両者の間に配設した剛性を有する高分子合成スポンジ体に接着してなるフェアリング部材を取付部材を介して車体と台車の間の隙間を塞いで取り付ける構成とした。
【0009】
なお、ここで、外側シートとは車体と台車間に取り付けた状態において車輌の外部側に位置するシートを指称し、内側シートとは同取付状態において車輌の内部側に位置するシートをいう。また、両シートの縦方向、横方向とは長尺側を縦方向、短尺側を横方向と称している。
【0010】
このように、外側シート及び内側シートは長尺方向に低伸度、短尺方向に高伸度の異方弾性性能をもつ編物等の異方弾性シート材で構成すれば、車体と台車間に取り付ける場合、編物等の異方弾性シート材の長尺方向を長手方向に配すれば、風圧を受けた際に膨らみの原因となる長手方向の伸びを抑えることができる。ここで、長手方向とは、台車の側面における車体との空間部を覆う場合には車体の上下方向を指し、台車の上部における車体との空間部を覆う場合は車体の前後方向を指称する。短尺方向には高伸度を有するため、カーブ、上下の勾配等、軌道変化に合わせて台車が変位する場合にもスムーズに追随可能である。
【0011】
また、外側シートと内側シートの間に剛性を有する高分子合成スポンジ体を配し、両シートを接着しているので、フェアリング部材全体としての断面剛性を向上させることができるとともに、風圧によるシートのバタツキを抑えることができる。
【0012】
従って、車両高速走行時の外気圧変化による膨らみを抑え、外側シートが空気抵抗によって波打つことによるバタツキを軽減し、かつ車両の変位に対して柔軟に対応できるフェアリング部材を提供し得る。
【0013】
外側シート及び内側シートは、基材を編物等の異方弾性シート材で構成し、その一面に伸縮復元性に富むエラストマーをコーティングするのが望ましく、その際、エラストマーは編物等の異方弾性シート材の表面繊維にのみ絡ませてコーティングすることが望ましい。ループ状にした繊維の遊び代を一側方向に配列すれば、容易に高伸度の方向と低伸度の方向を持った異方弾性性能を有する編物等の異方弾性シート材を構成することができ、エラストマーをコーティングすることによって耐久性を向上させることができる。伸縮復元性に富んだエラストマーを使用すれば基材としての編物等の異方弾性シート材の高伸度を生かすことができる。またエラストマーのコーティングに際し、編物等の異方弾性シート材の表面繊維にのみ絡ませるようにすれば、繊維がループ状をなす異方弾性シート材の繊維の遊び代を生かし、異方弾性シート材の異方弾性性能を生かすことができるとともに、異方弾性シート材自体の引裂強度を低下させることがない。
【0014】
また、基材としての編物等の異方弾性シート材は高強度の繊維、例えば芳香族ポリアミド繊維を緯編組織に編成することが望ましく、エラストマーとしては耐久性、伸縮復元性に富んだウレタンエラストマー、オレフィン系エラストマー及びシリコン樹脂のいずれか、高分子合成スポンジ体はネオプレンスポンジで構成するのが望ましい。
【0015】
たとえば、ケブラー(商標)のような高強度の芳香族ポリアミド繊維で緯編組織の異方弾性シート材を構成すれば、異方弾性シート材の引張強度と伸び量によって飛来物の衝撃エネルギーを吸収する良好な緩衝機能を持たせることができ、耐久性、伸縮復元性に富んだシリコン樹脂をコーティングすることによって、繰り返し高速走行によっても破損・裂傷が発生するおそれのない耐久性に富んだフェアリング部材並びにフェアリングを提供することができる。
【0016】
フェアリングは高速走行時、車両の進行方向に対して向かい合う場合は、空気流による動圧によってへこむ方向にあるが、フェアリング部材の裏側を軽量かつ高強度の金属板によって裏当てし、フェアリング部材の支持間隔を狭めてやれば、凹み量を少なくすることができる。
【0017】
【発明の実施の形態】
以下、本発明の実施の形態について説明する。
【0018】
図1は、本発明に係るフェアリング部材を使用したフェアリングの一実施態様を示す概略水平断面図で、台車の側面における車体との空間部を覆う場合を例示している。図2は超電導磁気浮上式鉄道車両の概略側面図で、車体Bと台車C間の連結部を覆うフェアリングとしては、台車Cの上部と車体Bの連結部を覆う上部フェアリングF1、車両進行方向に対して台車Cの前後と車体Bの連結部を覆う端部フェアリングF2、上部フェアリングF1と端部フェアリングF2のコーナー部における連結部を覆う隅部フェアリングF3及び車両の底面側において台車Cの前後と車体Bの連結部を覆う底面フェアリング(図示せず)などが設けられる。本発明に係るフェアリングは主として、車両進行方向に対して台車Cの前後と車体Bの連結部を覆う端部フェアリングF2として好適に使用し得るものである。
【0019】
図1において、フェアリング部材Aは、外側シート1、内側シート2並びに両シート間に配された剛性を有する高分子合成スポンジ体3によって構成されている。両シートは長尺方向に低伸度、短尺方向に高伸度の異方弾性性能をもつ編物等の異方弾性シート材で構成され、長尺方向を車体の上下方向に配することにより、風圧を受けた際に膨らみの原因となる長手方向の伸びを抑えるとともに、短尺方向には高伸度とすることにより、カーブ、上下の勾配等、軌道変化に合わせて台車が変位する場合にもスムーズに追随可能としている。
【0020】
外側シート1及び内側シート2は、いずれも基材を高強度の芳香族ポリアミド繊維であるケブラー(商標)を用いて緯編組織として天竺編で編成した異方弾性シート材で構成し、その一面に伸縮復元性に富むエラストマーであるシリコン樹脂をコーティングしている。このシリコン樹脂のコーティングに際しては編物等の異方弾性シート材の表面繊維にのみ絡ませてコーティングすることにより、異方弾性シート材の繊維の遊び代を生かし、異方弾性シート材の異方弾性性能を生かすとともに、異方弾性シート材自体の引裂強度を低下させないようにしている。シリコン樹脂の代りにウレタンエラストマーあるいはオレフィン系エラストマーを用いてもよい。
【0021】
外側シート1と内側シート2の中間層に配された高分子合成スポンジ体3は硬質のネオプレンスポンジを使用している。 外側シート1と内側シート2の間に剛性を有する高分子合成スポンジ体3を配して両シートを接着することによって、フェアリング部材に厚みをもたせ、断面剛性を向上させ、膨らみの低減作用を持たせるとともに、鉄道車両の高速走行時の空気振動による外側シート1のバタツキを防止している。なお、この例では、複数個の高分子合成スポンジ体3を縦横方向において複数列に配置しているが、台車と車体間の空間部が狭い個所、例えば台車上部の空間部に使用する場合などには長手方向に複数個の高分子合成スポンジ体3を一列に配しても良い。
【0022】
車体Bには取付部材4がボルト等で固定され、台車Cには取付部材5がボルト等で固定されている。前記フェアリング部材Aは、外側シート1及び内側シート2の端部を押え部材6と裏当て部材7の間に挟み込んでボルト・ナット8で取付部材4、5に取り付けられている。
【0023】
軽量かつ高強度の裏当て部材7を設けることにより、フェアリング部材Aの支持間隔が狭まり、空気流による動圧によって生じるへこみ量を抑制している。
【0024】
高速走行時に飛来する障害物による衝撃負荷エネルギーに対しては、高強度の繊維を用いて、長尺方向に伸び難く、短尺方向に伸び易くした異方弾性性能を有する編物等の異方弾性シート材を基材として耐久性、伸縮復元性、耐候性に富んだシリコン樹脂をコーティングすることにより、エネルギーを吸収する良好な緩衝機能を持たせるとともに、その材料の持つ高強度によって対応可能としている。
【0025】
フェアリング部材Aの長尺方向には、車両の上下方向の変位に対して剪断力が働き、平面において斜めの剪断線(剪断座屈後の剪断皺)が発生するが、内外両シート間に高分子合成スポンジ体3を設けて接着しているので、外側シート1の表面に生じる皺高さを抑えることが可能になる。
【0026】
【発明の効果】
本発明は上述の通り、それ自体で伸縮性を有するフェアリング部材を開発し、このフェアリング部材を取付部材を介して車体と台車間に取り付けることにより鉄道車両の車体と台車の間の隙間や段差を無くして平滑化するフェアリングとしたので、車両の走行方向に拘らず空気抵抗・空力音の低減を達成し得たのである。

BACKGROUND OF THE INVENTION
The present invention provides a fairing that is attached between a vehicle body and a bogie to reduce air resistance and aerodynamic noise by eliminating a gap or a step between the car body and the bogie of a railway vehicle such as a linear vehicle. It is about.
[0002]
[Prior art]
Recent railway vehicles, represented by linear vehicles, have increased in speed and the structure of the vehicle body is similar to that of an aircraft. The difference between a rail vehicle and an aircraft is that the rail vehicle has a carriage with wheels or superconducting magnets and needs to travel along the track. The running track is not only a straight line, but also changes in the track such as curves, up and down gradients, combinations of straight lines, curves and gradients, and the space between the carriage and the vehicle body that moves according to such changes in the track is high-speed. There is a problem that air resistance is generated during traveling, and air is disturbed and noise is generated in the space.
[0003]
Therefore, in order to cope with this point, there has conventionally been provided a fairing aimed at smoothing without a gap or a step between the vehicle body and the carriage. For example, as shown in FIG. 3, a fairing member D configured to be extendable and retractable by several rubbing plates is attached to the space between the carriage and the vehicle body with a mounting bracket so as to correspond to the displacement between the vehicle bodies B and C. A fairing configuration has been proposed (see Patent Document 1).
[0004]

Japanese Utility Model Publication No. 7-40344 (FIG. 4)
[0005]
[Problems to be solved by the invention]
However, this fairing has no particular problem when the traveling direction of the vehicle is a constant direction. However, when the traveling direction is the opposite direction, air enters the gap where the plates are overlapped, and is caused by high-speed fluid. There was a risk of breakage due to dynamic pressure. In addition, if the adhesion strength of the gap is improved so as to withstand this dynamic pressure, the movement resistance of the carriage becomes too large due to the strength to follow the change of the track, and the ride comfort deteriorates. Arise.
[0006]
Accordingly, an object of the present invention is to provide a fairing that reduces air resistance and aerodynamic noise by closing a space between a vehicle body and a carriage and smoothing without a gap or a step, regardless of the traveling direction of the vehicle. Accordingly, it is an object of the present invention to provide a fairing that can achieve a reduction in air resistance and aerodynamic sound and has durability.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, in the present invention, a fairing member having elasticity by itself was developed, and this problem was solved by attaching the fairing member between the vehicle body and the carriage via the attachment member. Is.
[0008]
That is, the fairing of the present invention is a polymer arranged between an outer sheet, an inner sheet, and both sheets in a fairing that smoothes without a gap or a step between a vehicle body and a carriage of a railway vehicle such as a linear vehicle. Made of synthetic sponge body, the outer sheet and inner sheet are made of anisotropic elastic sheet material such as knitted fabric with low elasticity in the vertical direction and high elasticity in the horizontal direction. A fairing member formed by adhering to a polymer synthetic sponge body having rigidity disposed between the two is attached by closing a gap between the vehicle body and the carriage via an attachment member.
[0009]
Here, the outer seat refers to a seat located on the outer side of the vehicle when attached between the vehicle body and the carriage, and the inner seat refers to a seat located on the inner side of the vehicle in the attached state. Further, in the longitudinal direction and the lateral direction of both sheets, the long side is referred to as the longitudinal direction, and the short side is referred to as the lateral direction.
[0010]
As described above, if the outer sheet and the inner sheet are made of an anisotropic elastic sheet material such as a knitted fabric having a low elongation in the long direction and a high elongation in the short direction, it is attached between the vehicle body and the carriage. case, Haisure the longitudinal direction of the anisotropic elastic sheet material of knitting such as in a longitudinal direction, it is possible to suppress the longitudinal elongation that causes swelling when subjected to wind pressure. Here, the longitudinal direction refers to the vertical direction of the vehicle body when covering the space portion with the vehicle body on the side surface of the carriage, and refers to the longitudinal direction of the vehicle body when covering the space portion with the vehicle body at the upper portion of the carriage. Since it has a high degree of elongation in the short direction, it can be smoothly followed even when the carriage is displaced in accordance with a change in the track such as a curve or a vertical gradient.
[0011]
In addition, since a synthetic polymer sponge body having rigidity is disposed between the outer sheet and the inner sheet and both sheets are bonded, the cross-sectional rigidity of the fairing member as a whole can be improved, and the sheet by wind pressure Can be suppressed.
[0012]
Therefore, it is possible to provide a fairing member that suppresses swelling due to a change in external atmospheric pressure during high-speed traveling of the vehicle, reduces fluttering caused by undulation of the outer seat due to air resistance, and can flexibly cope with vehicle displacement.
[0013]
It is desirable that the outer sheet and the inner sheet are made of an anisotropic elastic sheet material such as a knitted fabric, and the elastomer is coated on one surface with an elastic material having excellent elasticity for expansion and contraction. In this case, the elastomer is an anisotropic elastic sheet such as a knitted fabric. It is desirable to coat only the surface fibers of the material. By arranging the play allowance of the looped fibers in one side direction, an anisotropic elastic sheet material such as a knitted fabric having anisotropic elastic performance having a direction of high elongation and a direction of low elongation can be easily formed. The durability can be improved by coating the elastomer. If an elastomer rich in stretch and resilience is used, the high elongation of an anisotropic elastic sheet material such as a knitted fabric as a base material can be utilized. In addition, when the elastomer coating is applied only to the surface fibers of the anisotropic elastic sheet material such as a knitted fabric, the anisotropic elastic sheet material takes advantage of the play allowance of the fibers of the anisotropic elastic sheet material in which the fibers form a loop shape. Thus, the anisotropic elastic performance of the anisotropic elastic sheet material itself is not lowered.
[0014]
In addition, anisotropic elastic sheet materials such as knitted fabrics as base materials are desirably knitted with high-strength fibers, such as aromatic polyamide fibers, in a weft knitted structure. It is desirable that the polymer synthetic sponge body is made of neoprene sponge, either olefin elastomer or silicone resin.
[0015]
For example, if an anisotropic elastic sheet material with a weft knitting structure is composed of high-strength aromatic polyamide fibers such as Kevlar (trademark), the impact energy of flying objects is absorbed by the tensile strength and elongation of the anisotropic elastic sheet material. By applying a silicone resin that has a good cushioning function and is highly durable and stretchable, it has a durable fairing that does not cause damage or laceration even during repeated high-speed running. Members as well as fairings can be provided.
[0016]
When the fairing faces the traveling direction of the vehicle when traveling at high speed, it is in the direction of being dented by the dynamic pressure due to the air flow, but the back side of the fairing member is backed by a lightweight and high-strength metal plate, If the support interval of the members is narrowed, the amount of dents can be reduced.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
[0018]
FIG. 1 is a schematic horizontal sectional view showing one embodiment of a fairing using the fairing member according to the present invention, and illustrates a case where a space portion with a vehicle body on the side surface of the carriage is covered. FIG. 2 is a schematic side view of a superconducting magnetically levitated railway vehicle. As a fairing that covers the connecting portion between the vehicle body B and the carriage C, an upper fairing F1 that covers the upper portion of the carriage C and the connecting portion of the vehicle body B, vehicle traveling The end fairing F2 covering the front and rear of the carriage C and the connecting part of the vehicle body B with respect to the direction, the corner fairing F3 covering the connecting part at the corners of the upper fairing F1 and the end fairing F2, and the bottom side of the vehicle , A bottom fairing (not shown) that covers the front and rear of the carriage C and the connecting portion of the vehicle body B is provided. The fairing according to the present invention can be suitably used mainly as the end fairing F2 that covers the front and rear of the carriage C and the connecting portion of the vehicle body B in the vehicle traveling direction.
[0019]
In FIG. 1, the fairing member A is constituted by an outer sheet 1, an inner sheet 2, and a polymer synthetic sponge body 3 having rigidity disposed between both sheets. Both sheets are composed of anisotropic elastic sheet material such as knitted fabric with anisotropic elasticity performance with low elongation in the long direction and high elongation in the short direction, and by arranging the long direction in the vertical direction of the car body, Even when the carriage is displaced in accordance with track changes, such as curves and up and down gradients, by suppressing the elongation in the longitudinal direction that causes bulging when subjected to wind pressure, and by increasing the elongation in the short direction It is possible to follow smoothly.
[0020]
Each of the outer sheet 1 and the inner sheet 2 is made of an anisotropic elastic sheet material in which a base material is knitted with a tenter knitting as a weft knitting structure using Kevlar (trademark) which is a high-strength aromatic polyamide fiber. It is coated with a silicone resin, which is an elastomer with excellent elasticity. When coating this silicon resin, only the surface fibers of the anisotropic elastic sheet material such as knitted fabric are entangled and coated, taking advantage of the play allowance of the fibers of the anisotropic elastic sheet material, and anisotropic elastic performance of the anisotropic elastic sheet material In addition, the tear strength of the anisotropic elastic sheet material itself is not reduced. A urethane elastomer or an olefin elastomer may be used instead of the silicone resin.
[0021]
The polymer synthetic sponge body 3 disposed in the intermediate layer between the outer sheet 1 and the inner sheet 2 uses a hard neoprene sponge. By arranging a synthetic polymer sponge body 3 having rigidity between the outer sheet 1 and the inner sheet 2 and adhering both sheets, the fairing member is thickened, the cross-sectional rigidity is improved, and the swelling is reduced. In addition, the outer seat 1 is prevented from fluttering due to air vibration when the railway vehicle is traveling at high speed. In this example, a plurality of polymer synthetic sponge bodies 3 are arranged in a plurality of rows in the vertical and horizontal directions. However, when the space between the carriage and the vehicle body is narrow, for example, when used in the space above the carriage. Alternatively, a plurality of polymer synthetic sponge bodies 3 may be arranged in a row in the longitudinal direction.
[0022]
The mounting member 4 is fixed to the vehicle body B with bolts or the like, and the mounting member 5 is fixed to the carriage C with bolts or the like. The fairing member A is attached to the attachment members 4 and 5 by bolts and nuts 8 with the end portions of the outer sheet 1 and the inner sheet 2 sandwiched between the pressing member 6 and the backing member 7.
[0023]
By providing the lightweight and high-strength backing member 7, the support interval of the fairing member A is narrowed, and the amount of dent caused by the dynamic pressure due to the airflow is suppressed.
[0024]
Anisotropic elastic sheets such as knitted fabrics that have anisotropic elastic performance that is hard to stretch in the long direction and easy to stretch in the short direction using high-strength fibers against impact load energy caused by obstacles flying at high speeds The material is coated with a silicon resin that is rich in durability, stretch and resilience, and weather resistance, so that it has a good buffering function to absorb energy and can be supported by the high strength of the material.
[0025]
The longitudinal direction of the fairing member A, the shearing force acts against the vertical displacement of the vehicle, but the diagonal shear line (shear wrinkles shear locus Postbuckling) occurs in a plane, between the inner and outer sheets Since the polymer synthetic sponge body 3 is provided and bonded, the height of the ridge generated on the surface of the outer sheet 1 can be suppressed.
[0026]
【The invention's effect】
As described above, the present invention has developed a fairing member having elasticity by itself, and by attaching the fairing member between the vehicle body and the carriage via the attachment member, Since the fairing is smoothed without steps, the air resistance and aerodynamic noise can be reduced regardless of the direction of travel of the vehicle.
