Abstract
High-speed trains Ceiling, belong to mechanical manufacturing field, it is made up of upper epidermis, layer and intermediate layer, intermediate layer is arranged between upper epidermis and layer, upper epidermis and layer are aluminium sheet, intermediate layer is aluminum honeycomb texture, by glue and uses hot pressing mode to be combined into the base arrangement of entirety in upper epidermis, layer and intermediate layer.The present invention uses the equipment ceiling board of aluminum honeycomb sandwich structure fabrication, compares with the equipment ceiling board of general monolayer iron plate structure, has more light weight, shock resistance by force, the feature of sound insulation and noise reduction.The most effectively improve the safety of bullet train equipment chassis, and use is the most lasting, it is not necessary to often change, loss can be reduced, cost-effective.The noise bottom train can also be reduced and pass in compartment, promote the comfort of passenger.
Description
Technical field
The invention belongs to mechanical manufacturing field, particularly relate to a kind of high-speed trains Ceiling.
Background technology
China Railway High-speed is fast-developing, and it is the most convenient to bring to travelling.Passenger enjoy high ferro bring rapidly and efficiently while, more concerned with the security performance of bullet train.The equipment chassis cabin of bullet train is built with vitals such as drive system, brakes, air conditioning systems; so the protection to bullet train equipment chassis cabin is to ensure the important step that train safe travels; equipment compartment mounting base on train chassis; equipment chassis can be effectively protected not by object impact, such as the stone etc. splash on railway.And existing equipment ceiling board, generally it is made by monolayer iron plate, though the impact of splash can be kept out, protects equipment chassis, but owing to base plate uses monolayer iron plate to make, under long-term external impacts, surface can become uneven, need often to change.
Summary of the invention
The present invention is directed to the deficiency of above-mentioned technology, a kind of high-speed trains Ceiling is provided, base plate uses aluminum honeycomb sandwich structure to be designed, the mechanical property making base plate is further optimized, can not only keep out the impact of the splashing article such as gravel, antidetonation, corrosion resistance are the most further promoted；Key also resides in it and achieves lightweight, improves the safety and reliability of train operation, has good sound insulation and noise reduction effect, is conducive to improving the high-speed cruising of rail vehicle.
The technical scheme is that high-speed trains Ceiling, it is made up of upper epidermis, layer and intermediate layer, it is characterized in that: described intermediate layer is arranged between described upper epidermis and described layer, described upper epidermis and layer are aluminium sheet, described intermediate layer is aluminum honeycomb texture, by glue and uses hot pressing mode to be combined into the base arrangement of entirety in described upper epidermis, layer and intermediate layer.
The thickness of described upper epidermis is 1～5mm.
The thickness of described layer is 1～5mm.
The thickness in described intermediate layer is 3～10mm.
Described glue is two-component polyurethane adhesive water.
The invention have the benefit that the high-speed trains Ceiling that the present invention provides, use the equipment ceiling board of aluminum honeycomb sandwich structure fabrication, compare with the equipment ceiling board of general monolayer iron plate structure, have more light weight, shock resistance by force, the feature of sound insulation and noise reduction.The most effectively improve the safety of bullet train equipment chassis, and use is the most lasting, it is not necessary to often change, loss can be reduced, cost-effective.The noise bottom train can also be reduced and pass in compartment, promote the comfort of passenger.
Accompanying drawing explanation
Fig. 1 is the structural representation of high-speed trains Ceiling of the present invention.
In figure: upper epidermis 1, intermediate layer 2, layer 3.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
As shown in Figure 1, high-speed trains Ceiling, it is made up of upper epidermis 1, layer 3 and intermediate layer 2, intermediate layer 2 is arranged between upper epidermis 1 and layer 3, upper epidermis 1 and layer 3 are aluminium sheet, intermediate layer 2 is aluminum honeycomb texture, by glue and uses hot pressing mode to be combined into the base arrangement of entirety in upper epidermis 1, layer 3 and intermediate layer 2.
As it is shown in figure 1, high-speed trains Ceiling, the thickness of upper epidermis 1 is 1～5mm, and the thickness of layer 3 is 1～5mm, and the thickness in intermediate layer 2 is 3～10mm, and glue is two-component polyurethane adhesive water.
As it is shown in figure 1, the making step of high-speed trains Ceiling is as follows: upper epidermis 1 and layer 3 all use thickness to be the aluminium sheet of 2mm, the aluminum honeycomb using thickness to be 5mm；In surface of aluminum plate by 0.5 kilogram/roller coating two-component polyurethane adhesive water, overlap according to aluminium sheet, aluminum honeycomb, the composite sequence of aluminium sheet, lie in after having overlapped and on hot press, carry out hot pressing, hot press design temperature 80 DEG C, pressurize 45 minutes, after glue is fully cured, takes off and it is carried out sharp processing.
