Description

  The present invention relates to a railway vehicle structure having an outer panel.

Conventionally, a railway vehicle having a skirt diaphragm formed on a side structure has been developed (for example, Patent Documents 1 and 2). By adopting this skirt aperture shape in the side structure, it is possible to secure a wide interior width while satisfying the vehicle limit, and to increase the passenger capacity. In such a side structure of the skirt diaphragm, the support for connecting the outer plates is curved by plastic deformation in accordance with the skirt diaphragm.
Japanese Patent Laid-Open No. 9-109881 Japanese Patent No. 3493912

  However, it is not easy to accurately process a curved shape by a processing method in which a plate material for a column is plastically deformed.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a railway vehicle structure having an outer panel formed with a precision column.

  A railway vehicle structure according to the present invention is a railway vehicle structure having an outer panel, and the outer panel is a combination of an outer plate disposed outside the vehicle body and the cut first to fourth plate members. It has a long column main body portion that is formed in a rectangular cross-section and is combined with a column bonded to the outer plate.

  Each plate material is not plastically deformed, and the first to fourth plate materials are formed by cutting, and the highly accurate plate materials are combined in a rectangular cross section, so that a highly accurate column can be formed. That is, the strut can be accurately formed in a straight shape or a curved shape depending on the shape of the plate to be cut. Therefore, when joining a highly accurate support | pillar to an outer plate, since an outer plate deform | transforms according to the shape of a support | pillar, a highly accurate outer plate panel can be formed with a highly accurate support | pillar.

  In such a railway vehicle structure, when the first and second plate members of the support column extending in the longitudinal direction perpendicular to the plane portion of the outer plate have curved portions cut and curved in the longitudinal direction. preferable. By adopting this configuration, the column main body is manufactured with reference to the first and second plate materials having high accuracy, so that a column having a curved portion can be easily made with high accuracy. Thereby, a curved outer panel can be formed with high accuracy. If such an outer shape panel is used as, for example, a waist panel of a side structure, a side structure having a skirt diaphragm can be formed with high accuracy.

  In addition, as a part of the column, a flange portion formed in the longitudinal direction along the edge of the column main body, and an outer top portion that is joined to the outer plate and positioned outside the vehicle main body and on the inner side of the vehicle main body The corrugated plates that are alternately arranged in parallel and are formed in a corrugated cross-section, and adjacent corrugated plates sharing the outer plate are orthogonal to the extending direction of the outer top portion of the corrugated plate The outer top of the corrugated plate and the outer plate are continuously welded along the longitudinal direction of the outer top, and the main column and the outer plate are connected in the longitudinal direction of the column. It is preferable that the flange portion of the column and the longitudinal end portion of the inner top portion are welded continuously. By adopting such a configuration, the outer plate, the corrugated plate, and the support can be reliably welded, and the rigidity of the outer plate panel is enhanced.

  According to the present invention, the railway vehicle structure has an outer panel formed with a high-precision column.

  Hereinafter, a preferred embodiment of a railway vehicle structure according to the present invention will be described in detail with reference to the drawings.
