Abstract
The utility model discloses a carriage floor compound sandwich construction for the magnetic suspended vehicles and the whole compound plate sandwich construction is composed of the thin and reinforced metallic material faceplate with the upper and lower layers and a middle layer of thick and light foam core material. The upper and lower faceplates endure the inner pulling and pressing load resulting from the bending moment, while the foam core sandwich that is connected with and supports the faceplate endures the shearing stress resulting from the transverse force so as to increase the inertia moment of the sandwich construction section and increase the bending rigidity and at the same time to have the functions of sound and heat insulation and fire protection. The utility model changes the actuality that the traditional train must adopt the special materials with the function of sound and heat insulation which, however, contributes very little to the intensity of the structural rigidity and increases the weight. Compared with the non-sandwich construction, the deadweight of the compound sandwich construction is greatly reduced so as to meet the requirements of high intensity, high rigidity and low weight.
Description
Technical field
The utility model relates to a kind of track traffic transportation means, and specifically, the utility model relates to a kind of maglev vehicle compartment composite floor board.
Technical background
The single-skin panel railway car floor of adopting plain metal and non-metal steel wood mixed system to form in the known technology, not only load-carrying capacity is low, and intensity, rigidity are poor, and often damage, and need maintenance often.Can not satisfy requirement and the strength and stiffness requirement that make at a high speed floating railway car floor.For carrying passenger and goods, passenger seat is installed, equip the part mobile unit again, the high speed that associated load is passed to running mechanism is floated the railway car floor, and the floor panel structure of prior art can't be competent at.If use the single layer structure of prior art, must strengthen the size of thickening floor compartment, increase the deadweight of train.And heat-insulating, fire-preventing, sound insulation and noise reduction all can not satisfy the requirement of high speed train, more is not easy to have the maintenance and the maintenance of the parts such as the floating car running mechanism of magnetic of labyrinth.
Summary of the invention
The purpose of this utility model can not satisfy the defective of high-speed maglev train floor compartment structure at prior art, a kind of lightweight construction, heat-insulating, fire-preventing, sound insulation and noise reduction excellent performance are provided, be convenient to component maintenance and maintenance such as the floating car running mechanism of magnetic again, can satisfy the maglev vehicle compartment composite floor board of high-speed maglev train operating needs.
In order to achieve the above object, a kind of maglev vehicle compartment composite floor board that the utility model provides, comprise one and compartment bonded assembly floor covering, it is characterized in that, described floor compartment surface layer has one deck light foam core at least by being connected the sandwich structure that material panel of double layer of metal up and down on longitudinal floor beam and the lower edge beam framework and/or composite material face and middle one deck light foam core are formed between described interlayer.
Described panel can be the aluminum alloy plate materials panel and/or be galss fiber reinforced resin sheet material.
Described light foam core can be a multi-cellular structure PMI foam core material.
The utility model also comprises with described longitudinal floor beam, crossbeam and with the floor of being made up of special-shaped extruded aluminium section and composite panel that bearing links together and covering.Form floor cover frame frame after several the special-shaped extruded aluminium section Combination Welding, crimping wraps formation floor, special-shaped extruded aluminium section edge lid around the top panel of the composite panel of double layer of metal material panel and/or composite material face and middle one deck light foam core composition up and down.
The utility model has following beneficial effect than the railway car floor panel structure of prior art:
The panel of foam sandwich construction is the main stressed member of sandwich structure.When structure stress, mainly bear tension and compression load in the face that causes by moment of flexure by upper and lower panel, the foam core material then plays a part to connect and support panel in sandwich structure, is bearing the shearing stress that is produced by transverse force.This composite sandwich structural transmits load in the mode that is similar to H-girder.In total, the distance between the two panels has been kept in the adding of core, thereby has increased the sandwich structure cross sectional moment of inertia, has improved bending stiffness.Foam core material is as sandwich material, sound insulation, heat-insulating function have been had both, changed on the conventional train and must adopt special sound insulation, thermal insulation material but very less and the present situation of gaining in weight the contribution of rigidity of structure intensity, realized the application of foam core material sandwich structure on train body, for sandwich structure is applied to the practical experience that large-sized structural parts provides aspects such as design, technology, manufacturing.And because the density of core is low, under the condition of same load-carrying capacity, foam sandwich construction is compared with non-sandwich construction, and the deadweight of structure greatly alleviates, and has satisfied high strength, high rigidity, lightweight requirement.In addition, the sound insulation of the foam core material of open texture, heat-proof quality are better.The composite sandwich structural that the utility model adopted, number of parts is few, and simple shape is easy to manufacture, and is easy for installation, is convenient to other associated components Maintenance and Repair, satisfied the each side operating needs on floor, high speed train compartment.
