Therefore, in the hybrid structure of this embodiment, a single skin structure joint is employed at the joint between the double skin structure and the single skin structure.
- a double skin structure joint is employed, both the end portion on the outer side face plate 70 and the end portion on the inner side face plate 71 become joints, and both must be joined. Therefore, in the case of the hybrid structure of the present embodiment, the joint line length can be almost halved as compared with the case where the double skin joint is employed.
- the plate portion 75 from the end of the hollow portion 74 is a region where the structure of the extruded shape member changes from a double skin structure to a single skin structure, such as a vertical load due to the weight of electrical equipment mounted on passengers and railway vehicles, etc.
- the face plate is an area where the out-of-plane deformation is likely to occur.
- the vehicle outer side plate 70 and the vehicle inner side plate 71 are obliquely connected by the first rib 72 and the second rib 73 so that the rigidity from the double skin structure to the single skin structure continuously changes. .

Therefore, high stress associated with out-of-plane deformation of the double-sided plate is not generated.
- the lower side of the window opening 22 is formed at the position of the dashed line in FIG. That is, at the position of the window opening 22, the upper part is removed from the one-dot chain line in FIG.
- a window member (glass plate, acrylic plate or the like) is attached to the window opening 22 so that the clearance between the edge of the window opening 22 and the peripheral edge of the window member can be easily sealed.

- vertical ribs 77 (third ribs) are provided above the position of the upper side of the window opening 22. That is, the positions of the pair of oblique ribs 76 and the pair of vertical ribs 77 are symmetrically switched in the hollow extruded shape member 50 on the upper side and the hollow extruded shape member 50 on the lower side.
- the longitudinal end of the opening is formed at substantially the same position as the one-dot chain line.
- the air conditioning opening 81 is formed so that the end of the opening is disposed at the position, the gap between the vehicle outer side plate 70 and the vehicle inner side plate 71 is blocked by the vertical ribs 77.

Abstract
Description
本実施例では、軌条車両の一例として鉄道車両を用いて説明する。図1に本実施例の鉄道車両に供される鉄道車両構体全体を斜視図で示す。図1に示す鉄道車両構体1は、台枠10の幅方向110の両端部に立設される側構体20と、台枠10の長手方向120の両端部に立設される妻構体40と、側構体20と妻構体40の上端部に載置される屋根構体30から構成される。
台枠10は、二枚の面板と該面板同士を接続するリブから成るアルミニウム合金製の中空押出形材50を幅方向(形材の長手方向に交差する方向)に接合することによって構成される。中空押出形材50は、いわゆるダブルスキン構造の押出形材であり、その押出方向は鉄道車両構体1の長手方向120に沿っている。
同様に、側梁11に含まれる出入口下辺24が位置する部位も、ダブルスキン構造を有する中空押出形材50により構成される。従って、軽量化と剛性・強度を両立できる鉄道車両構体を実現することが可能となる。
側柱27によって、出入口開口部21および窓開口部22の側方(各開口部の垂直辺に沿う部位)が補強されて剛性が高められるので、垂直荷重に起因する変位も抑制されて高い応力の発生が抑制されるとともに、鉄道車両構体1の剛性や強度をより強固にできる。
これにより、ハイブリッド化による軽量化を享受しつつ、荷重に対する剛性および強度を確保可能な鉄道車両構体を実現することができる。
本実施例の中空押出形材50は、その断面形状が、車外側面板70の幅方向長さが車内側面板71の幅方向長さよりも長く、車内側面板71の両端部から車外側面板70に向かって外側に延びる第1のリブ72および第2のリブ73によって車外側面板70と車内側面板71とが接続された台形形状を有する。また、車外側面板70、車内側面板71、第1のリブ72および第2のリブ73によって囲まれる範囲を中空部74、それ以外の領域を板部75と称する。
本実施例の軌条車両により、軽量化を実現すると共に製作性を向上でき、ライフサイクルエネルギーを低減できる軌条車両を提供することが可能となる。
本実施例では、実施例1で説明した軌条車両の変形例について、鉄道車両構体を例にして説明する。図4には本実施例の軌条車両の斜視図を、図5には、図4に示す鉄道車両構体1におけるA-A断面図をそれぞれ示す。
図1に示した実施例では、出入口下辺24は、側梁11に含まれていたが、図4と図5に示す本実施例では側構体20に含まれている。また、実施例1の鉄道車両構体で記した空調装置を省略している。それ以外の鉄道車両構体1の構成は実施例1で説明した構成と同一であるため、以下の説明においては、それら実施例1と同一の構成については説明を省略する。
出入口開口部21と窓開口部22は、出入口上辺23、出入口下辺24、窓上辺25、窓下辺26が中空押出形材50の配置箇所に位置するよう形成される。窓開口部の窓上辺25と窓下辺26との間の高さ方向の中間部、および、窓下辺26と側構体20の下端部との間には、Tリブ付き押出形材60(シングルスキン構造)により構成されている。側構体20の出入口開口部21および窓開口部22の側方(垂直辺)には、側構体20を補強する側柱27が設けられる。
本実施例では、実施例1で説明した軌条車両の更に別の変形例について、鉄道車両構体を例にして説明する。図6には、本実施例の軌条車両の斜視図を、図7には、図6に示す鉄道車両構体1におけるA-A断面図をそれぞれ示す。出入口上辺23が存在する部位以外の鉄道車両構体1の構成は、図1に示した実施例と同一のため、同一部部分についての説明は簡略化する。
図1に示した鉄道車両構体1では、出入口上辺23は、側構体20に存在していたが、本実施例では屋根構体30の幅方向110の端部に備えられる肩部31に存在している。屋根構体30は中空押出形材50のみによって構成されている。屋根構体30に高い強度が要求される場合、例えば1つの軌条車両上に2台の空調装置80(図示なし)を搭載する場合などには、本実施例の屋根構体30を採用する方が好ましい。
以下では、図8を用いて、本発明の軌条車両構体に対する比較例について説明する。実施例1~3では、側構体20がハイブリッド構造、すなわちTリブ付き押出形材60と中空押出形材50を形材の幅方向に組み合わせて接合された構造を備えていたが、本比較例ではTリブ付き押出形材60のみ、すなわちシングルスキン構造のみで構成されている。
側構体20は、Tリブ付き押出形材60を接合することによって構成される。側構体20と側梁11には、側構体20を補強する側柱27が、窓開口部22の側方に設けられる。肩部31に存在する出入口上辺23が位置する部位は、中空押出形材50により構成されている。側構体20に存在する窓上辺25、窓下辺26が位置する部位は、Tリブ付き押出形材60により構成されている。側梁11に存在する出入口下辺24が位置する部位は、中空押出形材50により構成されている。
