Resistance strain-gauge transducer is made of to utilize strain-type shift theory.It by experience object being measured stress or
Generated strain when torque, and strain variation dress is changed to resistance variations, voltage or electric current are further converted by electric bridge
Variation.Concrete principle is as follows:
1, strain-type shift theory
Illustrate strain-type shift theory with metallic resistance silk.Section is that the resistance value of circular metallic resistance silk is
R=ρ L/S=ρ L/ π r2 (1)
R-resistance value in formula (1)；
ρ-resistivity；
L-wire length；
S-wire cross-sectional area；
R-wire cross-sectional area radius.
For metallic resistance silk when it receives pulling force and extends dL, cross-sectional area will accordingly reduce dS, and resistivity is then because of gold
The influence for belonging to distortion of lattice factor will also change d ρ, change dR so as to cause the resistance of wire.Formula (1) differential can be obtained into formula
(2), formula (3):
DR=L*d ρ/π r2+ρ*dL/πr2-2ρL*dr/πr3 (2)
DR/R=d ρ/ρ+dL/L-2dr/r (3)
As the resistance wire of one-dimensional beaer, axial strain εL=dL/L and radial strain εr=dr/r meets formula (4):
εr=-μ εL (4)
μ-metallic resistance wire material Poisson's ratio in formula (4).
Formula (5) can be obtained using formula (3), (4):
K=dR/R/ εL=d ρ/ρ * εL+(1+2μ) (5)
K is the gage factor of metal material in formula (5), indicates resistance change rate caused by unit strain.
From formula (5): K is bigger, and the opposite variation of resistance caused by unit deformation is bigger, i.e., sensitiveer.
2, metal strain plate
Metal strain plate can be made in the strain effect of wire.It is generally by sensitive grid, substrate, adhesive layer, lead-out wire
It is formed with cover plate etc..Sensitive grid is made of filament, is fixed in substrate with adhesive.The effect of substrate is will to survey structure
Part is transmitted on sensitive grid without distortion, therefore very thin, generally 0.03-0.06mm.In addition, substrate have it is good insulation,
Moisture resistance and heat resistance, and it is small with change of external conditions deformation.Coating is pasted above sensitive grid, for protecting sensitive grid.It is quick
Feel gate resistance silk both ends and weld lead-out wire, to connect with external circuits.
3, transversal effect and sensitivity
When straight wire is by simple tension, any micro- section of strain experienced is all identical, and each section all extends.Cause
This, each section of resistance of wire rod will all increase, and the increase of all-in resistance is the increased summation of each micro- section of resistance.When the wire rod of same length
When metal strain plate is made, in the curved segment of resistance wire, the change rate and straight section of resistance are significantly different.In this way, foil gauge is sensitive
Coefficient is smaller than the sensitivity coefficient of straight section wire rod.In view of a kind of actual measurement situation, the cross sensitivity C=0.03 of foil gauge, quilt
It surveys workpiece and is in plane stress state, then relative error is ξ=3.9%.
4, the dynamic response characteristic of foil gauge
When dynamic measures, mechanical strain is propagated in the material in the form of the strain waveform for being equivalent to acoustic speed.Strain
Wave, through adhesive, substrate to sensitive grid, needs the regular hour by material for test surface.The above two are all very thin, can ignore not
Meter, but when strain wave sensitive grid length direction upload sowing time, will having time lag, to dynamic (high frequency) strain measurement just
Error can be generated.The dynamic response characteristic of foil gauge is exactly response characteristic when it is changed over time.
5, the temperature error and its compensation of foil gauge
As resistance strain gage, perfect condition is only become with strain in measurement, without being influenced by any other factor.
But in fact, the resistance variations of foil gauge are greatly influenced by temperature.It can be with the examination of free wxpansion when foil gauge is mounted on one
When on part, test specimen is not by the effect of any external force, if environment temperature changes, the resistance of foil gauge also becomes therewith
Change.If being not excluded for this influence in strain measurement, very big error certainly will be brought to measurement.It is this by variation of ambient temperature
Bring error is referred to as the temperature error of foil gauge, also known as thermal output.But if reasonably selecting foil gauge and using component just
It can make additional strain zero caused by temperature.Using the method for bimetallic sensitive grid self compensation piece, it utilizes temperature-coefficient of electrical resistance
Two kinds of resistance wire material in series of different (one is positive, and one is negative) are combined into sensitive grid.The resistance R1 of this two sections of sensitive grids
It is respectively Δ R1 and Δ R2 with R2 resistance variations due to caused by temperature change, they are equal in magnitude, and symbol is on the contrary, reach
The purpose of temperature-compensating.
6, electrical bridge principle
The strain for being measured generation can be incuded using foil gauge, the resistance value for obtaining resistance changes.Then pass through electricity
The variation that the resistance value of resistance occurs is converted into voltage or current signal by bridge.
