Abstract

The invention provides railway train body made of magnesium alloy and manufacturing method thereof. The railway train body made of magnesium alloy comprises a train underframe, a train top, two side walls and two end walls, and the train body is a box type structure formed by welding the train underframe, the train top, the two side walls and the two end walls, wherein the train underframe, the train top, the two side walls and the two end walls are formed by welding magnesium alloy profiles. By adopting the magnesium alloy train body formed by welding the magnesium alloy profiles, the railway train body made of magnesium alloy and the manufacturing method thereof realize the light weight of the railway train body and simultaneously solves the problem of resource limitation by using aluminum alloy to manufacture the train body.

Description

technical field [0001] Embodiments of the present invention relate to rail train technology, in particular to a magnesium alloy rail train body and a manufacturing method thereof. Background technique [0002] Rail passenger trains (high-speed trains-EMUs, maglev trains, branch line passenger trains, urban light rail trains, subway trains, etc.) are a type of rail transportation equipment with large passenger capacity, high operating efficiency, and high technical content. core part. The rail train body, the so-called car body in the industry, is the upper structure of the rail train and the core structure for transporting passengers. The body of rail trains is generally connected by the underframe, side walls, roof, and end walls, among which the underframe, side walls, roof, and end walls are welded by metal structures of different structures. . [0003] With the increase of train running speed, the lightweight of car body has become the basic element of train design an...
