Vehicle body with integral window corner and railway vehicle

Abstract

The invention provides a vehicle body with an integral window corner and railway vehicle. The vehicle body comprises two side wall modules forming right angle butt joint; the two side wall modules comprise inner plates and outer plates; the vehicle body ensures that the two side wall modules are connected into a whole body through the integral window corner; the integral window corner comprises a first surface plate which is fixedly connected with the inner plates of the two side wall modules, and a second surface plate which is fixedly connected with the outer plates of the two side wall modules; the first surface plate and the second surface plate are connected through a vertical plane plate; and the first surface plate, the second surface plate and the vertical plane plate are integrally formed. The vehicle body and the railway vehicle have the advantages that inner and outer plates of the two side wall modules are connected into a whole body through the integral window corner structure, the whole welding accuracy is effectively ensured, and stress concentration in the window corner position is reduced and eliminated.

Description

technical field [0001] The invention relates to the technical field of railway vehicles, in particular to a vehicle body with integral window corners and a railway vehicle. Background technique [0002] Existing railway vehicles usually adopt a modular design concept, such as lightweight stainless steel car body, its structure includes side wall modules, the connection between each side wall module mainly adopts thin plate lap joint and connecting plate structure, and the welding mainly adopts automatic spot welding technology. The joints of the side wall modules, especially the window corners, bear the alternating loads of longitudinal force tension, compression and vertical shear force, which are the main stress concentration areas of the entire car body structure and directly affect the overall strength of the car body. [0003] The connection at the window corners of module 1 on both side walls of the existing car body mainly adopts the spot welding connection method of...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the existing side wall module connection technology is that the two connection plates are not integrated. When bearing the longitudinal compression, tensile load and vertical load of the vehicle body, especially when passengers get on and off the vehicle, the connection is subjected to vertical alternating loads. And the shear force is relatively large, and this place itself is a stress concentration area, causing structural distortion and local instability at the joint. Long-term operation will affect the structural strength of the car body, and there are potential safety hazards for vehicle operation.
