Description

A kind of skirt plate of railway vehicle
Technical field
The invention belongs to skirtboard field used for rail vehicle more particularly to a kind of skirt plate of railway vehicle with sound insulation function.
Background technique
Rail vehicle tends to take up stone, ice cube or other sundries, to track during running at high speed forward The bottom of vehicle causes to impact, and damages interior important equipment and cable circuit.Existing technical solution is in track vehicular sideview Skirtboard is installed, it is desirable that skirtboard high-impact, light-weight, sound insulation, resistance to folding is tired and facilitates overhaul of the equipments.
Chinese patent CN105383142A discloses a kind of technique of composite material production high-speed rail equipment compartment apron board, the equipment Cabin skirtboard is made of mainboard surrounding press strip, and mainboard belongs to aramid fiber honeycomb sandwich structure, and press strip preimpregnation material bag is pressed;The skirtboard Mainboard aramid fiber honeycomb and the unidirectional carbon fiber prepreg adhesive-free film of two sides are excessive, and the ability for bearing shearing and removing is weak.
Chinese patent CN 206344819U discloses a kind of skirt plate of railway vehicle structure, skirt design hinge function, Support function and installation function are in the novel mounting base of one.But the novel mounting base and skirtboard are what matching die squeezed out Profile, weight is big, and type face is complicated, not easily molded.
Chinese patent CN104742923A discloses a kind of Straddle type monorail vehicle car body, the connection including bottom skeleton sum Apron board structure, upper layer skirtboard include the outer layer of the glass reinforced plastic formation of internal layer made of Pierced Aluminum Plank and pre-buried supporting rib.But The apron board structure weight is big, is not suitable for the maintenance to equipment in bogie.
It can be seen that the skirtboard of the rail vehicles such as existing high-speed rail, EMU, subway mostly use greatly aluminum honeycomb, aluminum profile and Glass reinforced plastic, there are weight big, poor rigidity, installation and maintenance difficult, moulding dullness feature, is unfavorable for the quick hair of high-speed railway Exhibition.If developing the method for preparing skirtboard of the light-weight, sound insulation of one kind and high-impact, the quick of high-speed railway will be advantageous to Development.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the shortcomings of to mention in background above technology and defect, provide height Anti-impact, light-weight, sound insulation skirt plate of railway vehicle.
In order to solve the above technical problems, technical solution proposed by the present invention are as follows:
A kind of skirt plate of railway vehicle is layer structure, is followed successively by aramid fiber/carbon fiber shuffling scrim cloth from outside to inside A, froth bed, aramid fiber/carbon fiber shuffling scrim cloth B and sound insulation lamella.
Above-mentioned skirt plate of railway vehicle, it is preferred that the aramid fiber/carbon fiber shuffling scrim cloth A and aramid fiber/ Carbon fiber shuffling scrim cloth B with a thickness of 0.3~0.7mm;The froth bed with a thickness of 7.5~9mm;The sound insulation lamella With a thickness of 1~2mm.
Above-mentioned skirt plate of railway vehicle, it is preferred that the material of the sound insulation lamella is any one in PVC, EVA or TPU Kind.Select these types of material as sound insulation sheet material, molding processibility, chemical stability, fillable can be high, meet railcar The performance requirement of skirtboard.
Above-mentioned skirt plate of railway vehicle, it is preferred that the aramid fiber/carbon fiber shuffling scrim cloth A and aramid fiber/ The surface density of carbon fiber shuffling scrim cloth B is 150~200g/m2;Surface density is too low, then surface impact is poorer;And face Density is excessively high, then does not meet weight loss effect.The surface density of the sound insulation lamella is 500~800g/m2;Surface density is too low, then every Audio fruit is poor;Surface density is excessively high, then flexibility is deteriorated, and is not suitable for being bonded with corner.
Above-mentioned skirt plate of railway vehicle, it is preferred that the material of the froth bed is PET foam, PMI foam, hard PU bubble Any one in foam.These types is light-weight foamed, machinability is strong, rigidity is big, ensure that molding skirtboard specific strength and than rigid It spends all higher.
Above-mentioned skirt plate of railway vehicle, it is preferred that the density of the froth bed is 50~120kg/m3;The density mistake of foam Low, then rigidity is poor, and the anti-pressure ability of skirtboard is weaker;If density is excessively high, weight and machinability are deteriorated, it is difficult to which processing band is bent The structure in face.
Above-mentioned skirt plate of railway vehicle, it is preferred that on the vehicle skirtboard by epoxy construction be adhesive with U-shaped aluminum profile and Gas spring mounting base.U-shaped aluminum profile is mounted at the top of skirtboard, is used for connects hinge, overturns skirtboard;Gas spring is installed, skirtboard is beaten When opening, gas spring can provide upward support force.
Above-mentioned skirt plate of railway vehicle, it is preferred that tensile-sbear strength >=20MPa of the epoxy structural rubber guarantees U-shaped aluminium profiles The gentle spring mounting seat of material is fixedly mounted in skirt plate of railway vehicle.
Compared with the prior art, the advantages of the present invention are as follows:
(1) aramid fiber/carbon fiber shuffling cloth is used in high-impact skirt plate of railway vehicle as skirtboard by the present invention for the first time Exterior skin improves the shock resistance of skirtboard;Meanwhile aramid fiber/carbon fiber shuffling cloth and foam sandwich construction combine, 50% or more loss of weight can be realized relative to aluminum alloy apron board.
(2) present invention is bonded in skirtboard back using sound insulation piece, improves the sound insulation value of skirtboard, so that sound transmission loss is kept In 32dB or more.
(3) skirtboard of the present invention is easy to transport and install, can reduce wheel track noise transmission to car.
