Abstract
Description
そこで本発明は、横荷重に対する車体強度を高めた鉄道車両を提供することを目的とする。また、既存の車両にも容易に適用可能な補強構造を備えた鉄道車両を提供することを目的としている。
[車両]
列車は、複数の車両1を連結することによって構成されており、車両1は、線路上を走行する2つの台車(図示せず)を有している。この2つの台車の上には、図示しない空気ばねを介して車体3が載せられており、車体3は、図1に示すように底部に台枠4を有している。
補強構造30は、2つの第1補強構造部31と第2補強構造部32とを備えている。第1補強構造部31は、荷棚11とそれに隣接する吊り手取付具20とに架け渡すように夫々設けられており、2つの補強パイプ33,34と、複数の連結パイプ35とを有している。
第2実施形態の車両1Aは、第1実施形態の車両1と構成が類似している。そこで、以下の第2実施形態の車両1Aの構成の説明では、第1実施形態の車両1と異なる構成についてだけ説明し、同一の構成については同一の符号を付して説明を省略する。第3実施形態の車両1Bの構成の説明についても同様である。
第3実施形態の車両1Bは、図4に示すように第1握り棒15及び第2握り棒16を備えておらず、腰掛部材10と荷棚11との間に部材が介在していない点が第1実施形態の車両1と異なっている。
以下では、第1~第3実施形態の車両1,1A,1Bの補強効果を確認するために行ったFEM解析(使用プログラム:LS-DYNA MPPver.971(64bit版))について説明する。なお、本実施形態の車両1の比較対象として図5及び図6に示すような車両101や、車両101に関して第3補強構造50だけが取り付けられた車両(図示せず)についてもFEM解析も行った。車両101は、補強構造30を有していない点を除いて車両1と略同様の構成であり、同一の構成について同一の符号を付してその構成の説明を省略する。
FEM解析で使用した解析モデルは、図7Aに示すように車両の一部を切り取ったものである。詳細に説明すると、解析モデルは、車両の長手方向において出入口5aの中央から隣接する窓5bの中央までの部分で1つの戸先柱45と戸尻柱46とを含む部分を切り取ったものである。また、FEM解析では、図7Bに示すように、車両が角度30度に傾斜してY方向に初速50km/hで剛体壁47に衝突する条件のもとで解析を行った。
図8及び図9には、前述のFEM解析によって得られた解析結果が示されている。まず、図8に示す解析結果について説明すると、図8には、戸尻柱46付近にて切断された断面において剛体壁47から最も離れている点W(図7B参照)、具体的には台枠4と戸尻柱46とが連結されている点WのY方向変位量(即ち、車幅方向の変位量であり、剛体壁47に遠ざかる方向を正方向とする)の経時変化が示されている。なお、図8のグラフでは、縦軸が変位量(上側が正方向)であり、横軸が経過時間である。また、図9には、各解析モデルの客室7の体積の経時変化が示されている。なお、図9に示す解析結果は、出入口中央位置、戸先柱位置、戸尻柱位置、及び窓中央位置の各断面において図7Bに示すような点U1~U10の断面積計測点を設定し、これら10点の断面積計測点に基づいて客室7の体積が解析されている。なお、図9のグラフでは、縦軸が体積であり、横軸が経過時間である。図8及び図9では、一点鎖線Aが第1実施形態の車両1に関する解析結果、二点鎖線Bが第2実施形態の車両1Aの解析結果、長破線Cが第3実施形態の車両1Bの解析結果を夫々示している。また、破線Dは、第1補強構造部31及び第2補強構造部32を取り外して第3補強構造部50だけを採用した車両の解析結果を示し、実線Eが従来の車両101の解析結果を示している。
図10に示す第1変形例の車両1Cは、第2実施形態の車両1Aの変形例であり、第3補強構造部50に代えて第3補強構造50Cが採用されている。以下の第1変形例の車両1Cの構成の説明では、第2実施形態の車両1Aと異なる点である第3補強構造50Cの構成についてだけ説明し、同一の構成については同一の符号を付して説明を省略する。なお、第2変形例の車両1Dの構成の説明についても同様である。
図11に示す第2変形例の車両1Dの第3補強構造部50Dは、パイプ受け57とパイプ部材58とを有している。パイプ受け57は、上下方向に延在する受け部材であり、台枠4の横梁4a上に固定されている。パイプ受け57には、第2支持部材となるパイプ部材58が立設されており、パイプ部材58は、パイプ受け57と第2握り棒16とを連結している。
第1実施形態乃至第3実施形態では、第1補強構造部31及び第2補強構造部32がトラス構造を形成しているが、必ずしもトラス構造に限定されない。例えば、連結パイプ35がなくてもよい、また連結パイプ35を上下方向に渡して梯子のような構造にしてもよい。
