Description
Technical field
The utility model relates to a kind of stopping sliding door of bullet train, especially a kind of door panel structure of Plug Door of High-speed Train.
Background technology
In recent years, along with train is to high speed and modernization future development, car door is had higher requirement, as car body outward appearance smoothly (air resistance be subject to when can reduce vehicle operating and the noise of generation thereof attractive in appearance at closing time, improve indoor sound insulating and tightness, to meet comfort requirement) etc.For this reason, 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 construction 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 due to the coefficient of thermal conductivity of metal material higher, easily cause local heat bridge phenomenon, thus reduce door-plate effect of heat insulation.Because door-plate local connecting portion not easily protects, often can there is corrosive liquids and invade door body, and cause the problem of door-plate premature failure.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of door panel structure adopting the Plug Door of High-speed Train of Composite Material Stiffened Panel structure.
The utility model solves the technical scheme that its technical problem adopts: a kind of door panel structure of Plug Door of High-speed Train, comprise the door-plate and doorframe that adopt composite material to make, described composite material take epoxy resin as matrix, T300 grade carbon fiber is as reinforcing material, described door-plate comprises exterior skin, reinforcing rib and inside panel, described exterior skin one-shot forming, exterior skin gluing is connected to reinforcing rib and window frame, reinforcing rib is made up of orthogonal crossyard and stringers, described doorframe encloses exterior skin edge one week, some box structures are formed by crossyard and stringers in doorframe enclosure, sound-insulating and heat-insulating filler is provided with in described cassette mechanism, there is between described inside panel and reinforcing rib one deck adhesive-layer, and pass through rivet interlacement.
The exterior skin of novel sliding-plug door panel, crossyard, stringers, doorframe and inside panel are composite material, and account for 75% of overall structure weight, comparing present metallic framework door can loss of weight 56%.Form some box structures by crossyard and stringers in doorframe enclosure, this box structure is airtight, can strengthen the rigidity of door panel structure.
Further, described doorframe gluing is connected to connection profile.Connect connection profile in doorframe gluing, the sealing of door-plate and vehicle body can be ensured.
Further, the corner of described connection profile is provided with connecting part of wrap angle.The corner installation kit angle connector of connection profile has the effect be tightly connected to connection profile.
Further, the connection profile 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 riveting part having and connect vehicle body hinge and effort formation is gluedd joint in the side of described door-plate.
Further, in described door-plate, pre-plugged has the pipeline of pipeline.
The beneficial effects of the utility model are:
1. the utility model is owing to adopting advanced composite material in a large number, and construction weight is about 35kg, and comparing present metallic framework door can loss of weight 56%;
2. the composite material that the utility model adopts has good corrosion resistance: existing structure mainly adopts the material such as carbon steel, aluminium alloys, corrosion resistance is poor, during the cleaning of train vehicle body, cleaning fluid has corrosivity usually, and easily remain in door and window, cause a body premature failure, the utility model, owing to adopting composite material, solves this difficult problem very well;
3. the utility model has good effect of heat insulation: original structure is owing to adopting metal construction, although adopt heat insulation packed layer, but still easily producing heat bridge problem, composite material of the present utility model, because its coefficient of thermal conductivity is much smaller than metal, has therefore fundamentally stopped the generation of heat bridge problem;
4. the utility model is better than existing structure application life: composite material of the present invention has good fatigue resistance and resistance to crack extension ability, under identical fluctuating load load condition, compare present metal framework structure, the utility model has longer application life;
5. the utility model and existing body structure matches criteria, without the need to revising existing body structure, system can be installed: change in composite material case in relevant metal construction, usual needs make suitable amendment to existing docking structure, additional capital is caused to drop into, the utility model has taken into full account existing body structure standard, there is good compatibility, do not need to modify to vehicle body.
