Description
Technical field
The present invention relates to the stopping sliding door of a kind of bullet train, the door panel structure of especially a kind of Plug Door of High-speed Train.
Background technology
In recent years, along with train develops to high speed and modernization direction, car door is had higher requirement, as car body outward appearance smooths (air drag being subject to when can reduce vehicle operation and the noise of generation thereof attractive in appearance at closing time, improve indoor sound insulating and air-tightness, to meet comfort requirement) etc..For this, high performance stopping sliding door is subject to the great attention of people.
The outstanding feature of stopping sliding door is sandwich and skeleton (section bar) structure of door-plate, has higher specific stiffness and specific strength.But owing to adopting metal structure in a large number, cause its construction weight general higher (being on average about 80kg).Door-plate nonmetal structure all adopts heat-barrier material, but owing to the heat conductivity of metal material is higher, easily causes local heat bridge phenomenon, thus reducing door-plate effect of heat insulation.Owing to door-plate local connecting portion not easily protects, corrosive liquids often can be occurred to invade door body the problem causing door-plate premature failure.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, and the present invention provides the door panel structure of a kind of Plug Door of High-speed Train adopting Composite Material Stiffened Panel structure.
The technical solution adopted for the present invention to solve the technical problems is: provide the door panel structure of a kind of Plug Door of High-speed Train, including the door-plate adopting composite to make and doorframe, described composite is with epoxy resin for matrix, T300 grade carbon fiber is as reinforcing material, described door-plate includes exterior skin, reinforcement and inside panel, described exterior skin one-shot forming, exterior skin gluing is connected to reinforcement and window frame, reinforcement is made up of orthogonal crossyard and stringers, described doorframe encloses exterior skin edge one week, some box structures are constituted by crossyard and stringers in doorframe enclosure, sound-insulating and heat-insulating implant it is provided with in described cassette mechanism, there is between described inside panel and reinforcement one layer of adhesive-layer, and pass through rivet interlacement.
The exterior skin of novel sliding-plug door panel, crossyard, stringers, doorframe and inside panel are composite, account for the 75% of overall structure weight, and comparing present metallic framework door can loss of weight 56%.Being constituted some box structures by crossyard and stringers in doorframe enclosure, this box structure is airtight, it is possible to strengthen the rigidity of door panel structure.
Further, described doorframe gluing is connected to connection section bar.At doorframe gluing direct type material in succession, it is ensured that the sealing of door-plate and vehicle body.
Further, the corner of described connection section bar is provided with connecting part of wrap angle.The corner installation kit angle connector connecting section bar has, to connecting section bar, the effect being tightly connected.
Further, the connection section bar of described doorframe side is provided with pressure sensitive rubber strip.Pressure sensitive rubber strip may be used for preventing folder by mistake.
Further, the side of described door-plate is gluedd joint the riveting part connecting vehicle body hinge and effort formation.
Further, in described door-plate, pre-plugged has the pipeline of pipeline.
The invention has the beneficial effects as follows:
1. due to the fact that and adopt advanced composite material in a large number, construction weight is about 35kg, and comparing present metallic framework door can loss of weight 56%；
2. the composite that the present invention adopts has good corrosion resistance: existing structure mainly adopts the material such as carbon steel, aluminium alloy, corrosion resistance is poor, when train vehicle body cleans, cleanout fluid is generally of corrosivity, and easily remain in door and window, cause door body premature failure, due to the fact that employing composite, solve this difficult problem very well；
3. the present invention has good effect of heat insulation: original structure is owing to adopting metal structure, although adopting heat insulation packed layer, but still it being easily generated heat bridge problem, the composite of the present invention, owing to its heat conductivity is much smaller than metal, has therefore fundamentally stopped the generation of heat bridge problem；
4. the present invention is better than existing structure service life: the composite of the present invention has good fatigue resistance and resistance to crack extension ability, under identical alternate load load condition, compares present metal framework structure, and the present invention has longer service life；
5. the present invention and existing body structure matches criteria, without revising existing body structure, system can be installed: changes in composite case in relevant metal structure, typically require and existing docking structure is made suitable amendment, additional capital is caused to put into, the present invention has taken into full account existing body structure standard, there is good compatibility, it is not necessary to vehicle body is modified.
