Rail vehicle body and preparation method thereof

Abstract

The invention discloses a rail vehicle body which is low in weight and renewable in resource, preserves heat and lowers noise. The rail vehicle body comprises a roof, end walls, a side wall and a bottom frame. The bottom frame comprises a bottom plate and a bearing structure. A vehicle main body is defined by the side wall, the roof and the bottom plate. The side wall and the roof are in fillet transition, the side wall and the bottom plate are in fillet transition, the vehicle main body is integrally formed by winding bamboo skin and resin, the end walls are fixed to the ends of the vehicle main body, and the vehicle main body is fixed to the bearing structure. The invention further discloses a preparation method of the rail vehicle body. The preparation method includes the steps of resin modification, wherein modifier and flame retardant are added to the resin; bamboo skin pretreatment, wherein the bamboo skin is subjected to water removal and antiseptic treatment, and then the bamboo skin is connected into a continuous bamboo skin belt; manufacturing of a mandrel; vehicle main body winding, wherein the bamboo skin belt winds around a mandrel in a transverse, longitudinal and spiral intersecting mode, and the modified resin is poured during winding; manufacturing of the end walls and the bearing structure; fixation of the end walls to the ends of the vehicle main body; fixation of the vehicle main body to the bearing structure.

Description

technical field [0001] The invention belongs to the technical field of railway transportation, and more specifically relates to a rail vehicle body. Furthermore, the invention relates to a method for producing the above-mentioned rail vehicle body. Background technique [0002] Rail vehicles include high-speed trains, bullet trains, subways, light rails, and maglev trains. The body is surrounded by roof, side wall, end wall and underframe, and the head of the head car body is also provided with a driver's cab structure and a hood covering its outside. The underframe is generally composed of a bottom plate and load-bearing beams such as edge beams, beams, buffer beams, and corbel beams connected below it. In order to meet the aerodynamic performance, the front of the car is set in a slender and streamlined shape, and the outer surface of the car body has a smooth transition. In order to pursue faster running speeds of rail vehicles such as bullet trains and high-speed rail...
