This force transducer elastomer structure can realize the scalar force measurement after passing through the paster, and has rigidity big, and the precision is high, characteristics such as processing simple manufacture.
Description
Technical field
The utility model relates to strain-type mechanics sensor elastic body, specifically a kind of scalar force snesor elastomer structure.
Background technology
When the normal force measuring rotating object, often only need to measure stressed size, and requirement is not done to the direction of power, namely only the scalar of power is measured.Such as, when aerogenerator works, thrust size suffered by it be measured, due to heading to face all the time wind come to.In wind direction not timing, heading will constantly change, and thrust direction just cannot be determined.If with traditional single component sensors, sensor just must be integrated on aerogenerator, rotates with aerogenerator, just thrust can be measured.The moment of inertia that such sensor own wt produces can affect aerogenerator and run, and blower fan does not have enough spaces in order to sensor installation yet, makes surveying work become difficulty.In addition, during measurement, sensor must ensure enough rigidity, and rigidity is large, and the strain of generation is just little, causes measuring accuracy not high.
Summary of the invention
The purpose of this utility model is to solve the problem, and provides a kind of scalar force snesor elastomer structure, has the sensor of this elastomer structure, and no matter how wind direction changes, can Measurement accuracy scalar power, and meets the requirement of high rigidity.
Realizing the technical solution of the utility model is: a kind of scalar force snesor elastomer structure, comprises lower frame, upper ledge, brace summer, brace table and strain beam; Described brace summer lower end is connected with lower frame upper surface, and its upper end is connected with upper ledge lower surface; Described brace table lower surface connects lower frame upper surface; Described strain beam lower end is connected with brace table upper surface, and its upper end is connected with upper ledge lower surface.
Around described brace table, many brace summers are evenly installed.
Described brace summer is preferably four.
Be provided with many with the strain beam be evenly arranged between described brace table upper surface and upper ledge.
Described strain beam is preferably four.
Described strain beam and upper ledge lower surface, brace table upper surface are vertical.
Described lower frame, upper ledge, brace summer, brace table and strain beam are processed by block of metal.
The beneficial effects of the utility model are:
1, the measurement of different directions variable force can be realized; No matter thrust F from which direction comes, and can resolve into F
1and F
2, and these two power to be all foil gauge by being attached to fore-and-aft direction and left and right directions directly measure, during such aerogenerator work, no matter how wind direction changes, and the size of suffered thrust is always F=(F
1 2+ F
2 2)
1/2, conveniently realize the measurement of thrust scalar.
2, measuring accuracy is high and elastic body rigidity is large; During use, lower frame is fixed, the stressed generation displacement of upper ledge, because brace summer is all connected with upper ledge with strain beam upper end, the displacement that namely brace summer and the upper end of strain beam produce is the same, the brace summer and the strain beam that connect upper ledge and lower frame will produce distortion, namely form strain.Brace table is comparatively large due to rigidity own, and producing distortion can ignore relatively.At this moment the relative displacement that brace summer and strain beam produce is equal, but is greater than strain beam due to brace summer length, and therefore strain beam can produce relatively large strain.Brace summer rigidity, much larger than strain beam, achieves while the high rigidity ensureing whole sensor elastomer, can realize high-acruracy survey again.
3, because no matter how wind direction changes, F can be passed through with sensor of the present utility model
1and F
2obtain the size of the power F that will measure, just do not need sensor to be arranged on aerogenerator to play rotation with one.This addresses the problem when measuring with traditional single component sensors, the impact that the moment of inertia that sensor own wt produces is run aerogenerator.
4, the utility model structure is simple, easy to process.

Specific embodiments
As shown in Figure 1, a kind of scalar force snesor elastomer structure, comprises lower frame 1, upper ledge 5, brace summer 3, brace table 2 and strain beam 4, is processed by block of metal; Described brace summer 3 lower end is connected with lower frame 1 upper surface, and its upper end is connected with upper ledge 5 lower surface; Described brace table 2 lower surface connects lower frame 1 upper surface; Described strain beam 4 lower end is connected with brace table 2 upper surface, and its upper end is connected with upper ledge 5 lower surface.Four brace summers 3 have been evenly arranged around described brace table 2.Four strain beams be evenly arranged 4 are installed between described brace table 2 upper surface and upper ledge.
As shown in Figure 2, the force cell 6 with scalar force snesor elastomer structure is a 2 D force sensor in fact, and dimension sensor measures the stressed size F in respective direction respectively

2 2)
1/2.
As shown in Figure 3, during use, lower frame 1 is fixed, the stressed generation displacement of upper ledge 5, because brace summer 3 is all connected with upper ledge 5 with strain beam 4 upper end, namely the displacement that brace summer 3 and the upper end of strain beam 4 produce is the same, the brace summer 3 and the strain beam 4 that connect upper ledge 1 and lower frame 5 will produce distortion, namely form strain.Brace table 2 is comparatively large due to rigidity own, and producing distortion can ignore relatively.At this moment the relative displacement that brace summer 3 and strain beam 4 produce is equal, but is greater than strain beam 4 due to brace summer 3 length, and therefore strain beam 4 can produce relatively large strain.In addition, brace summer 3 rigidity, much larger than strain beam 4, therefore realizes the high rigidity of whole sensor elastomer.
Described force snesor elastomer structure, during use, upper ledge 5 and lower frame 1 can exchange.
