Problems solved by technology

At present, the design of the rail vehicle body structure at home and abroad mainly uses a corrosion-resistant protective layer on the surface of the car body structure, but the protective layer does not have the function of structural independence and noise reduction. It is very likely to cause local peeling failure of the protective layer under the action

Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0018] As illustrated in the figure: the aluminum alloy body structure of the new multifunctional rail vehicle of the present invention is mainly composed of an outer layer structure 1, a middle layer structure 2 and an inner layer structure 3. Wherein, the middle structure 2 is composed of a honeycomb structure and a noise reduction sponge. The outer structure 1 mainly uses materials with strong corrosion resistance, such as aluminum alloy with high corrosion resistance; the main structure of the middle structure 2 is a honeycomb structure 4 and the noise-reducing sponge 5 filled in the honeycomb holes; the inner structure 3 mainly Select high-strength materials, such as high-strength aluminum alloy, high-strength titanium alloy or high-strength composite materials.

[0019] The outer layer structure 1 and the inner layer structure 3 can adopt an integrated design, ...

Abstract

The invention relates to an aluminum alloy car body structure of a rail car, and the aluminum alloy car body structure comprises an outer layer structure, a middle layer structure and an inner layer structure, wherein the outer layer structure is an anticorrosion structure and used for preventing the corrosion of a rail car body; the middle layer structure is a noise lowering structure and used for transferring load of an inner system and an outer system of the car body and lowering the noise of a carriage; and the inner layer structure is used for carrying the majority of load of the inner system and the outer system of the car body. Due to the adoption of the aluminum alloy car body structure, the problem of the existing and traditional rail car body structure that an anticorrosion protection layer needs to be coated on the surface of the car body and the protection layer easily drops for losing effectiveness can be solved. The middle layer structure not only can transfer the load of the car body structure, but also can lower the noise inside the car carriage.

Description

technical field [0001] The invention relates to an aluminum alloy body structure of a rail vehicle. Background technique [0002] Rail vehicles are located in environments ranging from ground to underground, and the working environment is relatively complex and harsh. Most of the time, rail vehicles work in long-term humid and semi-enclosed spaces. The rail vehicle body structure is an important part of the rail vehicle system, and its structural design needs to fully consider its practicability, safety and comfort. First, because most of the working hours of rail vehicles are in a long-term humid environment, which is corrosive to the car body structure, the car body structure needs to have a certain corrosion resistance; second, when rail vehicles run at high speed, due to The underground tunnel is a semi-enclosed space. The air in the tunnel is compressed and flows through the surface of the car body at high speed, which generates a lot of noise and has a great impact on...
