Body of a rail vehicle with a longitudinal support member, comprising a connecting panel with curvature

摘要

The vehicle has a coach body comprising a horizontal elongated girder metal sheet (1) and firmly connected with a vertical door and/or window pillar (2). The metal sheet comprises a T-shaped connecting metal plate (7) that is provided with a horizontal portion (9) and a vertical portion (10). The door and/or window pillar is firmly connected with the vertical portion of the connecting plate. The connecting plate is curved for reducing notch stresses between the vertical and horizontal portions. The metal sheet is made of a material with a smaller specific strength.
