Problems solved by technology

Although the above two welding methods with the side wall panels can reduce the welding deformation of the side wall panels to a certain extent, the appearance still cannot achieve the expected effect. At the same time, the welding strength of resistance spot welding and plug welding is relatively low. After the assembly welding is completed, the side wall of the car body needs to be leveled. The leveling time is long and the effect is unsatisfactory, which will easily lead to a long production cycle of the rail vehicle

Abstract

The invention relates to the technical field of rail vehicles, and discloses a vehicle body side wall structure and a rail vehicle. The vehicle body side wall structure comprises a side wall body andmultiple upright posts, the upright posts are arranged in the length direction of the side wall body at intervals, the section of each upright post is in a similar U shape, and the open side of each upright post and the side wall body are welded through laser into a whole. The vehicle body side wall structure has the advantages of being high in welding strength and low in weight.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a car body side wall structure and a rail vehicle. Background technique [0002] The body of a rail vehicle is mainly composed of an underframe, side walls, roof, and end walls. As the main load-bearing part of a rail vehicle, the side wall is required to have high strength, but the side wall is usually arranged with side window openings. After the hole is opened, it is easy to generate stress concentration at the opening position, which requires the side window to be reinforced at the window position to prevent stress concentration. [0003] The body side walls of traditional rail vehicles are made of carbon steel, and the cross-sectional shape of the columns on the existing side walls is usually hat-shaped, thus making the side wall structure heavier. Traditional side walls The structure has been unable to meet the increasingly lightweight needs of rail vehicles. [000...
