Embodiment Construction

[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0026] The rail vehicle side wall structure described in the present invention is mainly applied to the rail vehicle body.

[0027] Such as figure 1 As shown, the rail vehicle side wall structure mainly includes a plurality of side wall profiles 1 , upper side beam profiles 2 , door columns 3 , and window columns 4 . The side wall profile 1 and the upper side beam profile 2 are hollow aluminum alloy extruded profiles, and continuous welding is adopted between each profile in the length direction of the car body. Continuous welding is adopted on the outer side of the room, and segmental welding is adopted on the side wall structure and the inner side of the side beam of the underframe.

[0028] The side wall structure and the underframe, roof, end wall and other large components are welded to form a complete thin-walled cylindrical overall load...

Abstract

The invention discloses a side wall structure of a railway vehicle. The side wall structure comprises a plurality of side wall profiles and an upper edge beam profile arranged above the side wall profile, wherein the distance between the inner and outer contours of the upper edge beam profile at a transition between the roof and the side wall structure is greater than the distances between the inner and outer contours of two sides. The side wall structure of the railway vehicle meets the requirements on the strength, the rigidity and the fatigue of the vehicle, and has the advantages of light weight, high strength, production process simplification, attractive appearance and the like.

Description

technical field [0001] The invention relates to a closed wall panel, in particular to a rail vehicle side wall structure. Background technique [0002] With the development of our country's social economy and the acceleration of the pace of life, rail transit has become the most important means of transportation in urban traffic. At present, the operating speed of domestic EMUs has reached 380 kilometers per hour. Design requirements for strength, stiffness and lightweight structures. [0003] The existing car body side wall structure has imperfections in terms of door and window installation structure, overall rigidity, strength, etc., and cannot meet the requirements of faster vehicles. Contents of the invention [0004] The main purpose of the present invention is to solve the above technical problems and provide a rail vehicle side wall structure that improves the overall bearing capacity and meets the requirements of newer rail vehicles. [0005] For realizing the a...
