Abstract

The embodiment of the invention provides a railway vehicle. The railway vehicle comprises a cab, the cab comprises an integrally-formed cab cover body, and the cab cover body comprises an outer skin layer, an inner skin layer and a bearing framework arranged between the outer skin layer and the inner skin layer; the outer skin layer is formed by laying prepreg in a preset mold layer by layer; the bearing framework is laid on the outer skin layer to be integrally formed, and the two ends of the bearing framework are connected with the outer skin layer and the inner skin layer in a laying mode correspondingly; and the inner skin layer is formed on the bearing framework by laying prepreg layer by layer. The outer skin layer, the inner skin layer and the bearing framework are integrally formed, and the bearing structure and the appearance structure are combined; the outer skin layer is formed by laying the prepreg in the preset mold layer by layer, so that the stability of the size of the formed cab cover body is ensured; and the bearing framework is laid on the outer skin layer, and prepreg is laid on the bearing framework layer by layer, so that the deformation control of the bearing framework in the forming process of the cab is further enhanced.

Description

technical field [0001] The present application relates to the technical field of rail vehicle manufacturing, in particular, to a rail vehicle. Background technique [0002] The driver's cab is located at the end of the train and is the tractor of the train. Its structural design should not only meet the strength, stiffness requirements and manufacturability of the structure, but also reduce the self-weight of the structure as much as possible, and at the same time have a streamlined shape with good visibility and aerodynamic performance. As the speed of the train increases, the aerodynamic effect of the train becomes more and more significant. In order to solve the problem of air resistance caused by high-speed operation and improve the aerodynamic performance of the shape of high-speed trains, the shape of the driver's cab is optimized, and a streamlined driver's cab with good aerodynamic performance and beautiful appearance is adopted. [0003] The traditional cab head s...
