Abstract
The present invention relates to a kind of device for fixing wind-tunnel wedge, belong to wind-tunnel simulation of wind device and method.This device includes detachable base, metal cap, screw mandrel, nut, rubber spacer and wedge vertical pivot；Detachable base is the metallic plate being provided with T-shaped groove, is arranged on bottom wedge vertical pivot, adheres to one layer of rubber spacer in T-shaped groove and bottom metallic plate；Metal cap top adheres to one layer of rubber spacer；Wedge vertical pivot one end is fixed in T-shaped groove, and the other end connects has screw mandrel, screw mandrel to cover in metal cap；By the nut on rotary screw, the metal cap being buckled in screw mandrel top is promoted to move up so that it is to compress with wind-tunnel top, fixing wedge.Base groove of the present invention constrains wedge local deformation unstability, and base adds the contact area bottom wedge with wind-tunnel bottom surface, adds the stability of wedge；Multilayer rubber bed course makes wedge more uniform with wind-tunnel top board and contacts baseplate, adds anti-slide performance between the two, makes the fixing relatively reliable of wedge.
Description
Technical field
The present invention relates to a kind of new method wedge device used by wind tunnel test being carried out and reliably fixing, specifically relate to
And to the base fixing device set up for wedge with T-shaped groove, in base groove and base plate and metal
One layer of rubber spacer is respectively set up in crown face, so that wedge is fixing relatively reliable.
Background technology
Wind tunnel test is one of important method of research structure wind resistance, passive in air near-earth boundary region
In simulation, frequently with fixing wedge as turbulent flow generator.The Normal practice of wind1 tunnel laboratory is: first
Wedge is vertically placed on appointment position, wedge bottom directly and wind-tunnel contacts baseplate, then at its top screw mandrel
On cover cylinder with groove (hereinafter referred to as metal cap, generally aluminum material), finally by rotating wire
Nut on bar, makes metal cap upwards withstand on wind-tunnel end face, and wedge is vertically clamped in wind-tunnel end face and bottom surface
Between, the effect of wind load can be resisted to a certain extent.But, with metal cap and wind-tunnel bottom wedge
Base plate, top plate contact area are little, and be all by hard metal material between frictional force resist wind load.
Owing to frictional force (coefficient) is less, therefore it is susceptible to wedge by accident of blowing down.In order to Accident prevention occurs,
The test wind is the most relatively low, it is impossible to meet test requirements document well.
Summary of the invention
The technical problem to be solved in the present invention is, easy for existing for the existing conventional fixing means of wind-tunnel wedge
By wind or the relatively low problem of the test wind, a kind of relatively reliable fixing means is proposed, and can be significantly
Improve the test wind.
For achieving the above object, this method the technical scheme is that
A kind of device for fixing wind-tunnel wedge includes detachable base, metal cap, screw mandrel, nut, rubber
Rubber cushion layer and wedge vertical pivot；Described detachable base is the metallic plate being provided with T-shaped groove, detachable base
It is arranged on bottom wedge vertical pivot, adheres to one layer of rubber spacer in T-shaped groove and bottom metallic plate, be used for retraining
Wedge, strengthens its stability, improves the anti-slide performance between base and wind-tunnel base plate；Wedge vertical pivot one end is fixed
In T-shaped groove, the other end connects screw mandrel, and screw mandrel distal hood is in metal cap；By on rotary screw
Nut, promote being buckled in the metal cap on screw mandrel top and move up, so that it compresses with wind-tunnel top board；Can
Dismounting base-plate and metal cap top adhere to one layer of rubber spacer, under pressure, rubber spacer and wind
Contacting more uniform between top, hole, base plate, and coefficient of friction is also largely increased, wedge is fixing the most reliable.
Described detachable base uses 1cm thickness aluminium sheet to make, and there is deep T-shaped recessed of 5-6mm on surface thereon
Groove, recess width and length are mated with wedge dimensions.
Described rubber spacer thickness is 2-3mm.
As a kind of novel reliable wedge fixing means, the method is gathered around and is had the advantage that
1, this method is that wedge adds detachable base, and the T-shaped groove of base both can firmly limit wedge
Mobile, wedge local resistance to compression stability can be improved again；
2, this method metal cap upper surface, base groove and lower surface set up rubber spacer, under stress can
Making it contact evenly with wind-tunnel end face and bottom surface by deformation, closely, friction resistant ability is higher.Therefore solid
Fixed the most reliable, test wind speeds is wider.
Accompanying drawing explanation
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 schematic 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 base plate rubber spacers；
5 wedge vertical pivots；6 screw mandrels；7 nuts；8 metal caps；9 top board rubber spacers；10 wedge main bodys.
Detailed description of the invention
Below in conjunction with the accompanying drawings and technical scheme, the detailed description of the invention of the present invention is further illustrated.
As it is shown in figure 1, inlay rubber spacer 3 in the groove 2 of detachable base 1, glue at base end face
Patch rubber spacer 4.
As in figure 2 it is shown, at wedge vertical pivot 5 welded top one screw mandrel 6, (diameter is generally 2-3cm, length
8-10cm), screw mandrel overlaps a nut 7, metal cap 8 is buckled in screw mandrel 6 and pushes up, viscous at metal cap 8 top
Patch rubber spacer 9.
As it is shown on figure 3, wedge main body 10 is an entirety with wedge vertical pivot 5 and screw mandrel 6 consolidation, by removable
Unloading base (1-4) and lie in the position specified, wedge is vertically bumped in groove 2 so that it is be pressed on bed course 3.
By the nut 7 on rotary screw 6, promote metal cap 8 to move up and compress with wind-tunnel top board.Wind lotus
Carry effect under, nut top and wedge base plate rubber spacer 9 and 4 respectively with wind-tunnel top board and base plate
Between produce frictional force so that wedge device keeps stable.
Described detachable base uses aluminium sheet thick for 1cm to make, and surface has and can make to embed bottom wedge thereon
T-shaped groove deep for 5-6mm, 2mm thickness rubber spacer can be laid in groove；Adhere at aluminium sheet lower surface
The rubber spacer that 2-3mm is thick.Described metal cap top rubber cushion thickness 2-3mm, its size and shape according to
Metal cap determines.
