Abstract
The invention relates to a cover (A) for a test stand of performing aerodynamic measurement on vehicles (P). The cover comprises at least one transfer belt (2) which extends at least in the bottom area between front wheels and back wheels of the vehicle, and a plurality of support elements (4) which can be covered by plastic materials.
Description
Technical field
The present invention relates to the overcover of a kind of laboratory table for carrying out aerodynamics measurement at vehicle place, this overcover has at least one conveyer belt extended at least bottom section between the front wheels and rear wheels of vehicle.
Background technology
According to prior art, it is applied in the conveyer belt system in this kind of laboratory table or base material and generally makes by very thin steel band (tape thickness is less than 1mm) and/or by the very thin base plate (being made up of metal material or plastics) having micropore.The structure of these conveyer belts structure is significant for certainty of measurement.In order to reach this certainty of measurement, these structure mechanical failure to occurring during continuous operation are especially sensitive with pollution.
Summary of the invention
General object of the present invention be to provide a kind of construct for this conveyer belt overcover, especially bottom cover thing, this overcover can relatively robust and less expensive ground build and substantially insensitive in the application and be prone to repair.
According to the present invention, this purpose is accomplished by: this overcover for laboratory table is made up of substantially rigid support component, and this support component can be coverd with (bespannbar) with plastic material.
This overcover is preferably able to be assembled by the independent component of modular.
Particularly preferably, it is provided that artificial leather is as plastic material.
These support components be preferably able to by fibre-reinforced, especially carbon fiber reinforced plastic material constitute.At this, these support components are inserted in the satchel constituted in a plastic material, and wherein these satchels sew upFormed in plastic material or by being bonded in its lateral edge place.
The independent component of this overcover should by experiment platform application flexibility or in order to open maintenance feasibility and can be interchangeably inserted in overcover.At this, the particular advantage of the present invention is in that the material structure of this module, because these independent modules have relatively small weight.
For the size of the support component being made up of fibre-reinforced plastics and plastics/artificial leather material, equally exist higher motility, and having proven to as advantageously, the thickness of artificial leather thickness and carbon fiber reinforced support component selects respectively in the order of magnitude of 1mm.Therefore, meet the requirement of the mechanical load due to overcover on the one hand, meet the requirement for its weight and weight on the other hand.
The inwardly or outwardly rolling (Auf-undAbrollen) of this module is guaranteed in optimal manner during in order to work on check-out console, desirably, ratio between width and the width of carbon fiber reinforced support component of bag-like element (insertion for fibre reinforced support component) is chosen as about 4:3, that is, when the width of the support component being housed in satchel is 30mm, this satchel has the width of such as 40mm.
Accompanying drawing explanation
Below by way of the embodiment schematically shown, the details of present subject matter, feature and particular advantage are described in detail.
Wherein:
Fig. 1 illustrates the laboratory table (air channel) for measurement and positioning vehicle in laboratory table in the diagram, and for simulated roadway, conveyer belt is movably disposed in the lower section of this vehicle；
Fig. 2 illustrates the overcover according to the present invention in a top view；And
Fig. 3 illustrates the structure of the overcover according to the present invention in the sectional views.
Detailed description of the invention
Fig. 1 schematically shows the structure of the laboratory table according to the present invention, for instance the working region in air channel.Car P is positioned in the measured zone in air channel by positioner 1.Conveyer belt 2 is arranged on the lower section of this car P, this car P should be exposed to real air-flow behavior in air channel, and this conveyer belt is such as formed as the road moved in under-vehicle relative to this vehicle by two roller (not shown) being arranged on side as endless belt conveyer.The remainder of bottom or its main surface portion are designed to breathe freely, and therefore a part of air-flow can flow out or sucking-off down down.
Bottom cover thing A according to the present invention is modularly made up of assemblnig independent component 3 (see Fig. 2).Each independent component 3 is made up of multiple support components 4.These support components 4 are configured to lath-shaped in an illustrated embodiment, and are preferably made up of carbon fiber reinforced plastics for weight and stability reasons.These support components 4 preferably sew up on all sides in bag-shaped accommodation portion 5 or insert in accommodation portion 5, and these accommodation portions can be formed by the bonding of the plastic material at pocket lateral edges place.In order to roll this independent component 3 or overcover A without any problems and economical space saving, desirably, the ratio between the width x and the width y of carbon fiber reinforced support component 4 in bag-shaped accommodation portion is set as about 4:3 by outside rotating direction.
Material for this bag-shaped accommodation portion 5 is plastics, it will be preferred that artificial leather.Therefore module sane, that easily roll is created.Then, it is possible to be bonded into complete overcover A by many this modules 3.
Preferably by connecting device common to those skilled in the art, these independent components 3 are fitted together so that without influence on transmission band smoothly to outer rolling.
The overcover A that the physical dimension of these independent components 3 and modularity are constituted is configured to variable to a great extent.At the thickness of artificial leather when the thickness also about 1mm of the order of magnitude of about 1mm and support component 4, this weight can at about 3-4kg/m2The order of magnitude.
Except changing whole independent component 3 from overcover, it is also contemplated that, these support components 4 are removably arranged in its bag-shaped accommodation portion 5.
By the structure of the independent component 3 according to the present invention or overcover A, when weight is minimum due to the material used by composite construction, except higher absorb the effect clashed into except, additionally it is possible to pressure is evenly distributed on surface.Additionally, this structure also exhibits good rolling characteristics except high bearing capacity.Additionally, this device can also relatively easily clean, and can keep in repair without any problems by changing when single independent component damages.
