TRAIN INTER-CAR STRUCTURE FOR LOWER NOISE

摘要

PROBLEM TO BE SOLVED: To provide a train structure in which the inter-car part is closed with an exterior tarpaulin member for reducing noise, capable of reducing the noise generated from the exterior tarpaulin member and lowering the installation height of electric appliances installed on the roof.;SOLUTION: The train inter-car structure for reducing noise is configured so that the outer surface position X of tarpaulin segments 3 to be installed between the facing car end faces 1a of railroad cars 1 is set inside the car surface Y and that the ridge edge part of each car end face is formed in a curved surface 2. For the current conditions with the Shinkansen train in which the inter-car part distance D is 300 to 500 mm and the running speed is approximately 300 km/h, the distance H from the car surface to the outer surface position of the tarpaulin segment 3 is set to H=30 to 90 mm and the radius of curvature R of the vertical section of the curved surface 2 is set to R=100 to 200 mm. In the case the exterior tarpaulin member has flat shape, in the roof region, the outer surface position of this flat tarpaulin is set inside (below) the car surface and the ridge edge part of the roof region of the car end face is formed in a curved surface. In the left and the right side-face region, the outer surface of the flat tarpaulin is put identical to the car surface.;COPYRIGHT: (C)2008,JPO&INPIT
