Embodiment 1

[0027] A rail vehicle body, comprising a car body and an underframe, the car body is fixed on the underframe, and the car body has a second structural layer, a first structural layer and an outer protective layer sequentially from the inside to the outside, The second structural layer is formed by winding several layers of bamboo sheets impregnated with epoxy resin adhesive, and the first structural layer is formed by winding several layers of glass fibers impregnated with unsaturated polyester resin adhesive. The outer protective layer is made of epoxy resin. Its concrete preparation steps are as follows:

[0028] (1) Mandrel treatment: making a box mandrel, and coating the release agent on the mandrel surface;

[0029] (2) Preparation of the second structural layer: cut the original bamboo into thin bamboo slices with a length of 6m, a width of 25mm, and a thickness of 3mm, and bond them to a length of more than 150m. and the included angle are spirally wound on the mandre...

Abstract

The invention belongs to the technical field of railway transportation and discloses a car body of a track vehicle. The car body comprises a carriage body and a chassis, wherein the carriage body is fixed on the chassis; the carriage body successively comprises structure layers and an outer protective layer from inside to outside; the structure layers comprise a first structure layer and a second structure layer; the first structure layer is constituted through winding and binding of multiple layers of continuous fibers which are soaked with a first resin adhesive; the second structure layer is constituted through winding and binding of multiple layers of one type or multiple types of materials among bamboo, wood, hemp stalks, rattans, straws, reed stalks and silvergrass stalks which are soaked with a second resin adhesive; and the outer protective layer is made of an anti-aging and corrosion-resistant material. The car body of the track vehicle provided by the invention has the advantages of high intensity, wide sources of raw materials, green and environment-friendly effects, resource recycling, light mass and lower cost. The car body made of composite materials has an excellent high-damping characteristic; sound attenuation is high; and anti-vibration performance and acoustic performance of a train are improved greatly.

Description

technical field [0001] The invention belongs to the technical field of railway transportation, and more specifically relates to a 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, the lightweight design of the car body has become a necessary measure. There are two main ways to ...
