Problems solved by technology

At present, the side skirts of the existing bogies are relatively narrow, which does not form a side covering effect on the bogie cabin, resulting in the exposed side of the bogie, which affects the aerodynamic performance

Abstract

The invention relates to the field of rail train side skirts, and provides a rail train bogie side skirt structure and a rail train. The track train bogie side skirt structure is used to be arranged on opposite sides of the bogie cabin along the train width direction, and includes a side skirt body, the side skirt body includes a transition connecting plate, and an arc of the transition connecting plate The transitionally connected outer convex arc panel and the inner extension plate transitionally connected with the outer convex arc panel and extending toward the outward convex direction away from the outer convex arc panel. In the present invention, the side skirt plate body is provided with outwardly convex arc panels along the width direction of the train, thereby widening the side skirt plate laterally in the width direction of the train, so as to prevent the side skirt plate from resisting the bogie; in addition, the transition connecting plate, Both the outer convex arc panel and the inner extension plate are connected by arc surface transition, which increases the degree of streamlining, which is conducive to enhancing the diversion effect and improving aerodynamic performance.

Description

technical field [0001] The invention relates to the technical field of rail train side skirts, in particular to a rail train bogie side skirt structure and a rail train. Background technique [0002] The rail train bogie and the bogie cabin form a complex concave cavity structure, which is significantly disturbed by the ground effect, and the air flow is extremely complicated. The aerodynamic resistance in this area accounts for more than 25% of the whole vehicle resistance, which becomes the key issue of aerodynamic drag reduction of rail trains and the focus of aerodynamic optimization design. At present, the side skirts of the existing bogies are relatively narrow, and do not form a side covering effect on the bogie cabin, resulting in the exposed side of the bogie, which affects the aerodynamic performance. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the embo...
