Problems solved by technology

FRP hoods pollute the environment and cause harm to the human body during the production process, and the finished product is non-degradable and basically cannot be recycled; FRP has a low elastic modulus and poor toughness, and is easily deformed and cannot be adjusted in the product structure
[0004] In addition, the skeleton of the existing subway car head usually adopts a beam-column structure, the car body design and processing structure are relatively complicated, the positioning is not accurate during assembly and welding, and the inner and outer surface errors are relatively large after processing

Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] The subway locomotive head provided by the embodiment of the present invention includes a frame 40 and a skin. The frame 40 includes a plurality of plate girders. The plurality of plate girders are arranged along the longitudinal or transverse direction of the frame 40, and are assembled and welded by sockets at intersections. The entire frame 40 forms a "well"-shaped structure, and its structure and socket form can refer to image 3 and Figure 4 As s...

Abstract

The invention discloses a metro car head, which adopts aluminum skin. Compared with the existing glass fiber reinforced plastic, the metro car head is environmentally friendly in production process, can realize recycling, has high strength, high elastic modulus, high toughness, and is not easy to deform and adjustable in product structure. Compared with the previous beam-column structure, the whole frame is welded with aluminum plate, which can reduce the weight of the whole frame, and achieve better strength and stiffness of the car body. The invention also discloses a metro vehicle using thefront end.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a subway vehicle and its head. Background technique [0002] Out of aesthetic requirements, the front of the subway is mostly designed to be quasi-streamlined. In order to better realize skin forming, the front skin of subway vehicles is currently made of glass fiber reinforced plastics, and manual paste or vacuum introduction can well achieve curved surface forming. However, there is pollution in the production process of the FRP hood and the FRP is not degradable. [0003] FRP is fiber-reinforced plastic, using glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. FRP hoods pollute the environment a lot during the production process and cause harm to the human body. The finished product is non-degradable and basically cannot be recycled; FRP has a low modulus of elasticity and poor toughness, and is easily deformed and cannot be adjusted i...
