Abstract

The utility model discloses a combined material passenger train roof comprises following three -layer extremely down on the follow: outer covering, foam press from both sides core, inner skin, the foam presss from both sides pre -buriedly in the core has an aluminium alloy. The utility model has the advantages that: adopt the roof structure of sandwich form, pack the steel skeleton with the former interlayer of the pre -buried aluminium alloy of high strength foam replacement, improved the stiffness ratio greatly, lightened roof weight, accord with the light -weighted development trend of passenger train, roof integration shaping, the component parts of traditional roof that has significantly reduced has reduced assembly process and welding processes for the roof is easily installed, easy maintenance, and the greatly reduced cost of manufacture shortens the supply time simultaneously.

Description

A kind of composite coach roof
Technical field
This utility model relates to a kind of coach roof.
Background technology
Existing coach roof be by skin, steel skeleton, upholstery top board by the assembling of the technique such as welding, bolt connection after, then be assembled to form complete coach roof with the column bonding pad of the gusset of under body, front-back wall.Wherein skin many employings galvanized steel plain sheet, glass steel & aluminum section steel, upholstery top board many employings aluminium alloy epidermis.
The shortcomings such as it is big that steel roof has own wt, corrosion-resistant;Steel skeleton needs reinforcing carcass as main load-carrying construction around escape window, air-conditioning and the side door of roof, this adds increased roof weight;The foaming interlayer filled between steel skeleton can not effectively transmit load;It is inconspicuous that aluminium alloy roof has weight loss effect, high in cost of production shortcoming;It is various that metal roof has parts on the whole, and assembly process is numerous and diverse and keeps in repair the shortcomings such as difficult.
Utility model content
Utility model purpose: for the problems referred to above, the composite coach roof that the purpose of this utility model is to provide a kind of lightweight, structural behaviour is stable.
Technical scheme: a kind of composite coach roof, from top to bottom by following up of three layers: exterior skin, foam core, inside panel, is embedded with aluminium section bar in described foam core.
Described exterior skin, described inside panel are glass fiber reinforced epoxy resin composite, and described exterior skin thickness is 2mm, and described inside panel thickness is 1mm.
For adapt to passenger vehicle top board curved surface, reduce foam-formed during surface tension, described foam core is made up of the two-layer H60 profile plate of polyureas and polyvinyl chloride composite materials, and described foam core thickness is 37.5mm, and density is 60kg/m3
Offer storage glue groove on described profile plate surface, increase and glued joint area, strengthen adhesive strength.
After pre-buried, the surface of described aluminium section bar flushes with the surface of described foam core, to ensure the flatness of roof.
Described exterior skin is the ply angles of [0 °/90 °/0 °/90 °/0 °], and described inside panel is [0 °/90 °/0 °/90 °/0 °]sPly angles.
Beneficial effect: compared with prior art, the utility model has the advantages that: use the roof structure of sandwich formats, replace septum primum layer to fill steel skeleton with the pre-buried aluminium section bar of high intensity foam, substantially increase ratio of rigidity, alleviate roof weight, meet the light-weighted development trend of passenger vehicle;Roof integrated molding, greatly reduces the component parts of tradition roof, decreases assembly process and welding sequence so that roof is easily installed, easy-maintaining, is substantially reduced cost of manufacture, shortens the supply time simultaneously.
Accompanying drawing explanation
Accompanying drawing is this utility model schematic cross-section.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model, it should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model, after having read this utility model, those skilled in the art all fall within the application claims limited range to the amendment of the various equivalent form of values of the present utility model.
As shown in drawings, a kind of composite coach roof, formed sandwich structure by following three layers from top to bottom: exterior skin 1, foam core 2, inside panel 3.
Exterior skin 1, inside panel 3 are glass fiber reinforced epoxy resin composite, and exterior skin 1 thickness is 2mm, and inside panel 3 thickness is 1mm.Inside and outside eyelid covering use prepreg-autoclave forming process, laying direction be inside panel according to [0 °/90 °/0 °/90 °/0 °], exterior skin according to [0 °/90 °/0 °/90 °/0 °]sMode is carried out, and 0 ° of direction is passenger vehicle course (Z-direction) direction, and monolayer prepreg thickness is 0.22mm.
The thickness of foam core 2 is 37.5mm, and density is 60kg/m3.According to top board measure, in order to adapt to the curved surface of passenger vehicle top board, reduce foam-formed during surface tension, foam core 2 is made up of two-layer H60 profile plate 2-1, for polyureas and polyvinyl chloride composite materials, offer storage glue groove 5 on profile plate surface, be to increase splicing area, it is ensured that glue-joint strength.Pre-buried aluminium section bar 4 in foam core 2, is distributed according to mechanics, pre-buried after aluminium shape surface flush with foam core surface, to ensure product flatness.
Pre-buried aluminium section bar is coated with 7710 structure glue after surface processes;Lower eyelid covering splicing face is uniformly coated with 7710 structure glue, is placed on splicing loose tool;Profile plate is uniformly coated with 7710 structure glue, is placed on the exterior skin after gluing;Aluminium section bar after gluing is put in the collapsed position of profile plate, then place second layer profile plate, gluing;It is placed on after upper eyelid covering uniform gluing on second layer profile plate;Play vacuum bag, evacuation pressurization, solidification.
Before and after roof panels being cut according to drawing requirement skylight and enter, return air inlet etc., hole in roof panels, pre-buried insert, by the section bar being connected with under body gusset, front-back wall column splicing, be screwed in sandwich structure composite roof panels.
This utility model is abandoned, around skin, the loss of weight thinking of upholstery top board, by changing roof structure, using the material of high-strength light to realize maximum weight loss effect;By sandwich structure, increase the interlaminar shear strength of eyelid covering and foam core material, pre-buried aluminium section bar in foam core material, effectively transmitted load by rigid foam;Eyelid covering and the assembly problem of steel skeleton is solved in traditional handicraft and because steel skeleton interlayer can not effectively transmit the problem of stress concentration caused on the premise of reaching roof structure mechanical property;Skin and interior trim panel all use composite material skin, solve traditional metal skin corrosion resistance, fatigue durability, the shortcoming of thermal insulation difference by the chemical property that resin is excellent;Reduce roof number of parts in a large number by the global formation of roof, reduce assembly process, it is not necessary to welding tooling etc. realize easily installing, easy-maintaining.
