Description

【0001】
【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縦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。横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、縦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、横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、縦方向に伸び難く、横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の縦方向には、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。

TECHNICAL FIELD OF THE INVENTION
The present invention is directed to a fairing mounted between a vehicle body and a bogie to reduce air resistance and aerodynamic noise by smoothing by eliminating gaps and steps between the body and a bogie of a railway vehicle such as a linear vehicle. It is about.
[0002]
[Prior art]
The speed of recent railway vehicles represented by linear vehicles is increasing, and the structure of the vehicle body is similar to the structure of an aircraft. The difference between a railway vehicle and an aircraft is that a railway vehicle has a bogie with wheels or superconducting magnets and needs to travel along a track. The running track is not only a straight line, but also changes in the track, such as curves, vertical gradients, combinations of straight lines, curves, gradients, etc.The space between the bogie and the vehicle body displaced according to such track changes is high speed. There is a problem that air resistance occurs when the vehicle travels, and that air is disturbed in the space to generate noise.
[0003]
Therefore, conventionally, a fairing has been provided for the purpose of smoothing by eliminating a gap or a step between the vehicle body and the bogie in order to cope with this point. For example, as shown in FIG. 3, a fairing member D configured to be expandable and contractable with several rubbing plates is attached to a space between the bogie and the vehicle body with a mounting bracket so as to correspond to the displacement between the vehicle bodies B and C. A configuration of a fairing has been proposed (see Patent Document 1).
[0004]
[Patent Document 1]
Japanese Utility Model Laid-Open 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 constant, but when the traveling direction is reversed, air enters the gap where the plates are stacked, and It could be damaged by dynamic pressure. Also, if the tightness of the gap is increased to withstand this dynamic pressure, the resistance of the bogie to move becomes too large due to the strength, making it impossible to follow the change in the track, and the ride comfort deteriorates. Occurs.
[0006]
Therefore, an object of the present invention is to provide a fairing in which the space between a vehicle body and a bogie is closed and smoothed by eliminating gaps and steps to reduce air resistance and aerodynamic noise. Another object of the present invention is to provide a fairing that can achieve a reduction in aerodynamic resistance and aerodynamic noise 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 has been developed, and the above problem has been solved by attaching this fairing member between a vehicle body and a bogie via an attachment member. Things.
[0008]
That is, the fairing of the present invention is an outer sheet, an inner sheet, and a polymer disposed between both sheets in a fairing that eliminates a gap or a step between a vehicle body and a bogie of a railway vehicle such as a linear vehicle and smoothes it. The outer sheet and the inner sheet are composed of an anisotropic elastic sheet material such as a knitted fabric having a low elongation in the longitudinal direction and a high elongation in the lateral direction. A fairing member adhered to a rigid synthetic polymer sponge body having a rigidity disposed between the two members is attached by closing a gap between the vehicle body and the bogie 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 bogie, and the inner seat refers to a seat located on the inner side of the vehicle in the attached state. In addition, the longitudinal direction and the lateral direction of both sheets are referred to as a long side as a longitudinal direction and a short side as a lateral direction.
[0010]
As described above, if the outer sheet and the inner sheet are formed of an anisotropic elastic sheet material such as a knitted fabric having anisotropic elasticity with low elongation in the longitudinal direction and high elongation in the lateral direction, the outer sheet and the inner sheet can be attached between the vehicle body and the bogie. By arranging the longitudinal direction of the anisotropic elastic sheet material such as a knitted fabric in the longitudinal direction, it is possible to suppress elongation in the longitudinal direction which causes swelling when subjected to wind pressure. Here, the longitudinal direction refers to the vertical direction of the vehicle body when covering the space with the vehicle body on the side surface of the bogie, and refers to the front-back direction of the vehicle body when covering the space with the vehicle body above the bogie. Since it has a high degree of elongation in the lateral direction, it can smoothly follow even when the bogie is displaced in accordance with changes in the trajectory, such as a curve or a vertical gradient.
[0011]
In addition, since a polymer synthetic sponge body having rigidity is arranged between the outer sheet and the inner sheet and both sheets are adhered, the cross-sectional rigidity of the entire fairing member can be improved, and the sheet due to wind pressure can be improved. Flapping can be suppressed.
[0012]
Therefore, it is possible to provide a fairing member that suppresses swelling due to a change in outside air pressure during high-speed running of the vehicle, reduces flapping caused by the outer sheet waving due to air resistance, and can flexibly respond to vehicle displacement.
[0013]
The outer sheet and the inner sheet preferably have a base made of an anisotropic elastic sheet material such as a knitted fabric, and one surface thereof is coated with an elastomer having high elasticity and elasticity. In this case, the elastomer is an anisotropic elastic sheet such as a knitted fabric. It is desirable that the material be entangled and coated only on the surface fibers of the material. By arranging the play allowance of the looped fiber in one direction, an anisotropic elastic sheet material such as a knitted material having anisotropic elasticity having a high elongation direction and a low elongation direction can be easily formed. And durability can be improved by coating with an elastomer. The use of an elastomer having a high elasticity can restore the high elongation of an anisotropic elastic sheet material such as a knitted fabric as a base material. Also, when the elastomer is coated, only the surface fibers of the anisotropic elastic sheet material such as a knitted fabric are entangled, so that the fibers can make use of the play allowance of the loop-shaped anisotropic elastic sheet material, and the anisotropic elastic sheet material can be used. And the tear strength of the anisotropic elastic sheet material itself is not reduced.
[0014]
Further, it is desirable that the anisotropic elastic sheet material such as a knitted fabric as a base material is formed by knitting a high-strength fiber, for example, an aromatic polyamide fiber into a weft knitting structure. It is preferable that the polymer synthetic sponge body of any one of olefin-based elastomer and silicone resin be composed of neoprene sponge.
[0015]
For example, if a high-strength aromatic polyamide fiber such as Kevlar (trademark) is used to form an anisotropic elastic sheet material having a weft knitting structure, the impact energy of a flying object is absorbed by the tensile strength and elongation of the anisotropic elastic sheet material. A durable fairing that has a good cushioning function and is coated with a silicone resin that is highly durable and stretch-restoring, so that there is no risk of breakage or tearing even during repeated high-speed running. Members as well as fairings can be provided.
[0016]
When facing the traveling direction of the vehicle during high-speed driving, the fairing is in the direction of dent by the dynamic pressure of the air flow, but the back of the fairing member is backed by a lightweight and high-strength metal plate, If the distance between the members is reduced, the amount of depression can be reduced.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
[0018]
FIG. 1 is a schematic horizontal sectional view showing an embodiment of a fairing using a fairing member according to the present invention, and illustrates a case where a space between a side surface of a bogie and a vehicle body is covered. FIG. 2 is a schematic side view of a superconducting magnetic levitation type railway vehicle. As a fairing covering a connecting portion between the vehicle body B and the bogie C, an upper fairing F1 covering an upper portion of the bogie C and the connecting portion of the vehicle body B, The end fairing F2 covering the connection between the front and rear of the carriage C and the vehicle body B in the direction, the corner fairing F3 covering the connection 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) or the like that covers a connecting portion between the front and rear of the carriage C and the vehicle body B is provided. The fairing according to the present invention can be suitably used mainly as an end fairing F2 that covers a connection portion between the front and rear of the bogie C and the vehicle body B in the vehicle traveling direction.
[0019]
In FIG. 1, the fairing member A is composed of an outer sheet 1, an inner sheet 2, and a rigid polymer synthetic sponge body 3 disposed between the two sheets. Both sheets are made of an anisotropic elastic sheet material such as a knitted fabric having anisotropic elasticity with low elongation in the vertical direction and high elongation in the horizontal direction.By arranging the vertical direction in the vertical direction of the car body, the wind pressure is reduced. In addition to suppressing longitudinal elongation that causes swelling when received, high elongation in the horizontal direction allows smooth movement even when the bogie is displaced according to track changes such as curves, vertical gradients, etc. It is possible to follow.
[0020]
Each of the outer sheet 1 and the inner sheet 2 is composed of an anisotropic elastic sheet material in which the base material is knitted with a weft knitting structure using a high-strength aromatic polyamide fiber, Kevlar (trademark), in a weft knitting structure. Is coated with silicone resin, which is an elastomer that is highly elastic. When coating with this silicone resin, the surface fibers of the anisotropic elastic sheet material such as a knitted fabric are entangled and coated to take advantage of the play allowance of the fibers of the anisotropic elastic sheet material, and the 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-based 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 rigid synthetic polymer sponge body 3 between the outer sheet 1 and the inner sheet 2 and bonding the two sheets together, the fairing member is given a thickness, the sectional rigidity is improved, and the bulging reduction effect is obtained. In addition, the outer seat 1 is prevented from flapping due to air vibration during high-speed running of the railway vehicle. In this example, the 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 bogie and the vehicle body is narrow, for example, when used in a space above the bogie. For example, a plurality of polymer synthetic sponge bodies 3 may be arranged in a line in the longitudinal direction.
[0022]
The mounting member 4 is fixed to the vehicle body B with bolts and the like, and the mounting member 5 is fixed to the truck C with bolts and the like. The fairing member A has the ends of the outer sheet 1 and the inner sheet 2 sandwiched between the holding member 6 and the backing member 7 and is attached to the attachment members 4 and 5 with bolts and nuts 8.
[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 generated by the dynamic pressure due to the air flow is suppressed.
[0024]
An anisotropic elastic sheet material such as a knitted fabric with anisotropic elasticity that uses high-strength fibers to make it difficult to stretch in the vertical direction and to stretch easily in the horizontal direction against the impact load energy caused by obstacles flying at high speeds By coating a silicone resin with high durability, elasticity and resilience and weather resistance as a base material, it has a good buffering function to absorb energy, and can cope with the high strength of the material.
[0025]
In the longitudinal direction of the fairing member A, a shearing force acts on the vertical displacement of the vehicle, and an oblique shear line (shear wrinkle after shear buckling) is generated in a plane, but the height between the inner and outer sheets is high. Since the molecular synthetic sponge body 3 is provided and bonded, the height of wrinkles 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 bogie via the mounting member, the gap between the vehicle body and the bogie of the railway vehicle is improved. Since the fairing eliminates the steps and smoothes, the air resistance and aerodynamic noise can be reduced regardless of the running direction of the vehicle.
