Abstract

The present invention relates to a kind of for fixing the device of wind-tunnel wedge, belong to wind-tunnel simulation of wind device and method.The device includes detachable base, metal cap, screw, nut, rubber spacer and wedge vertical pivot;Detachable base is the metallic plate equipped with T-shaped groove, is arranged on wedge vertical pivot bottom, T-shaped groove is interior and metallic plate bottom adheres to one layer of rubber spacer;One layer of rubber spacer of adherency at the top of metal cap;Wedge vertical pivot one end is fixed in T-shaped groove, and the other end is connected with screw, and screw is covered in metal cap;By the nut on rotary screw, the metal cap for being buckled in screw top is pushed to move up, make it with being compressed at the top of wind-tunnel, fixed wedge.Base groove of the present invention constrains wedge local deformation unstability, and pedestal increases the contact area of wedge bottom and wind-tunnel bottom surface, increases the stability of wedge;Multilayer rubber bed course makes wedge and wind-tunnel top plate and contacts baseplate more uniform, increases anti-slide performance between the two, the fixation for making wedge is relatively reliable.

Description

A kind of device for being used to fix wind-tunnel wedge
Technical field
The present invention relates to a kind of new methods being reliably fixed to wedge device used in wind tunnel test, and in particular to for Wedge adds the base fixing device with T-shaped groove, in base groove and base plate and metal cap top surface respectively add one layer Rubber spacer, so as to make the fixation of wedge relatively reliable.
Background technology
Wind tunnel test is one of important method of research structure wind resistance, the passive simulation in air near-earth boundary layer In, frequently with fixed wedge as turbulent flow generator.The Normal practice of wind1 tunnel laboratory is:Wedge is placed on to finger vertically first Positioning is put, and cylinder with groove (following letter directly with wind-tunnel contacts baseplate, is then covered in wedge lower part at the top of it on screw Claim metal cap, generally aluminum material), finally by the nut on rotary screw, metal cap is made to withstand on wind-tunnel top surface upwards, point It splits and is clamped in vertically between wind-tunnel top and bottom, the effect of wind load can be resisted to a certain extent.However, wedge bottom Portion and metal cap and wind-tunnel bottom plate, top plate contact area are little, and are resisted by the frictional force between hard metal material Wind load.Since frictional force (coefficient) is smaller, wedge easily occurs and is blown down accident.Accident occurs in order to prevent, experiment Wind speed is often relatively low, it is impossible to meet test requirements document well.
Invention content
The technical problem to be solved by the present invention is to easy by wind present in for the existing common fixing means of wind-tunnel wedge Blow down or the problem of the test wind is relatively low, propose a kind of relatively reliable fixing means, and the test wind can be greatly improved.
To achieve the above object, this method the technical solution adopted is that:
It is a kind of for fix wind-tunnel wedge device include detachable base, metal cap, screw, nut, rubber spacer and Wedge vertical pivot;The detachable base is the metallic plate equipped with T-shaped groove, and detachable base is arranged on wedge vertical pivot bottom, T In type groove and metallic plate bottom adheres to one layer of rubber spacer, for constraining wedge, enhances its stability, improves pedestal and wind-tunnel Anti-slide performance between bottom plate;Wedge vertical pivot one end is fixed in T-shaped groove, and the other end is connected with screw, and screw main header casing is in gold Belong in cap;By the nut on rotary screw, the metal cap for being buckled in screw top is pushed to move up, so as to make itself and wind-tunnel top Plate compresses;One layer of rubber spacer of adherency at the top of detachable base-plate and metal cap, under pressure, rubber spacer and wind-tunnel It is contacted between top, bottom plate more uniformly, and friction coefficient is also largely increased, wedge is fixed more reliable.
The detachable base is made of 1cm thickness aluminium sheets, and there is the T-shaped groove of 5-6mm depths on surface on it, and groove is wide Degree and length are matched with wedge dimensions.
The rubber spacer thickness is 2-3mm.
As a kind of novel reliable wedge fixing means, this method possesses advantages below:
1st, this method increases detachable base for wedge, and the T-shaped groove of pedestal not only can firmly limit wedge movement, but also can To improve wedge part resistance to compression stability;
2nd, rubber spacer is added in this method metal cap upper surface, base groove and lower surface, can pass through deformation under stress It is made to be contacted with wind-tunnel top and bottom evenly, closely, anti-friction ability is stronger.Therefore fixed more reliable, the test wind Range is wider.
Description of the drawings
Fig. 1 is the detachable base schematic diagram of wind-tunnel wedge fixing means device of the present invention.
Fig. 2 is the upper metal cap schematic diagram of wind-tunnel wedge fixing means device of the present invention.
Fig. 3 is the overall structure diagram of wind-tunnel wedge fixing means device of the present invention.
In figure:1 detachable base;2 base grooves;Rubber spacer in 3 grooves;4 bottom plate rubber spacers;5 wedge vertical pivots;6 Screw;7 nuts;8 metal caps;9 top plate rubber spacers;10 wedge main bodys.
Specific embodiment
Below in conjunction with the accompanying drawings and technical solution, the specific embodiment further illustrated the present invention.
As shown in Figure 1, inlaying rubber spacer 3 in the groove 2 of detachable base 1, rubber spacer is pasted in base end face 4。
As shown in Fig. 2, in 5 one screw 6 (diameter is generally 2-3cm, length 8-10cm) of top welding of wedge vertical pivot, screw A nut 7 is above covered, metal cap 8 is buckled in screw 6 pushes up, and pastes rubber spacer 9 at 8 top of metal cap.
As shown in figure 3, wedge main body 10 is an entirety with wedge vertical pivot 5 and the consolidation of screw 6, by detachable base (1- 4) position specified is lain in, wedge is bumped into vertically in groove 2, it is made to be pressed on bed course 3.Pass through the nut on rotary screw 6 7, metal cap 8 is pushed to move up and is compressed with wind-tunnel top plate.Under the action of wind load, nut top and wedge base plate rubber Rubber cushion layer 9 and 4 generates frictional force between wind-tunnel top plate and bottom plate respectively so that wedge device keeps stablizing.
The detachable base is made of the aluminium sheet of 1cm thickness, and there is the 5-6mm that can be embedded in wedge bottom on surface on it Deep T-shaped groove can be laid with 2mm thickness rubber spacers in groove;In the rubber spacer of aluminium sheet lower surface adherency 2-3mm thickness.Institute Metal cap top rubber cushion thickness 2-3mm is stated, size and shape are determined according to metal cap.
