Description
Technical field
This utility model is related to the structural strain fields of measurement of engineering mechanics, proposes a kind of two ends and carries two-dimentional code labeling
Strain measurement wire.
Background technology
General elastomeric objects can produce certain deforming under being acted on by external force, and the degree of deformation claims to strain.Strain has
Normal strain (line strain), shear strain (angular strain) and body strain.Wherein, normal strain formula is ε=Δ L/L, and in formula, L is deformation
Front length, Δ L is the elongation after its deformation.
At present, widely used electrical measuring method in strain measurement method.Electrical measuring method make use of metallic resistance silk to bear stretching or press
During compression deformation, resistance is also by the principle changing.Resistance wire is back and forth coiled into special shape (as palisade) so that it may make resistance
Foil gauge.Before measurement, resistance strain gage is pasted at the position of strain to be surveyed with special adhesive, when housing is made by load
During with deforming, the resistance wire in resistance strain gage deforms therewith together, leads to resistance wire length and the change of sectional area, from
And cause the change of its resistance value.It can be seen that, the change of resistance has certain corresponding relation with strain.By resistance strain gauge, just
Corresponding change can be recorded.Recycle Hooke's law or other theoretical formulas so that it may try to achieve stress value.
It can be seen that, used in electrical measuring method, measurement hardware mainly includes：Resistance strain gage, resistance strain gauge, resistance strain gage
Connecting wire and between deformeter, other electric supply installations etc..This utility model is aiming between resistance strain gage and deformeter
Connecting wire and put forward.
When static(al) or dynamic experiment are carried out to large scale structure, particularly Chinese large-sized guided missile, heavy launcher shell
Body experimental verification scene, in order to obtain the mechanical response in the case of loaded load of structure, is answered to structure using electrical measuring method
Become the core measuring often this experiment, and strain measuring point often up to hundreds of, this results in resistance-strain
Connecting wire between piece and resistance strain gauge measurement port is excessively so that strain corresponding between measuring point and resistance strain gauge port
Relation is extremely complex.In formal experimentation, generally require the strain measurement value of monitoring of structures specific location measuring point at the scene
Situation of change, this is accomplished by straining measuring point numbering according to specific location searches the corresponding connecting wire number of this measuring point, then root
Search the resistance strain gauge measurement end slogan of this wire connection according to connecting wire number, just permissible at resistance strain gauge control software end
Obtain the strain measurement value at the resistance strain gage that this measurement port is connected according to measurement end slogan.By above corresponding relation
Search operation just can obtain the strain measurement value of the structure specific location measuring point specified.If needing supervision in experimentation
Measuring point is enough, then corresponding relation search operation amount as described above will greatly increase, and considerably increases out
Wrong risk.In addition, it is also desirable to recycle connection to lead according to resistance strain gauge measurement end slogan in experimental data last handling process
The measuring point numbering obtaining its corresponding resistance strain gage reversely searched by line.
As fully visible, when strain measurement being carried out to structure using electrical measuring method, need following corresponding relation：1) structural strain is surveyed
The corresponding relation at the connecting wire end that point is numbered and at this, resistance strain gage is connect；2) company being connect according to resistance strain gage at this
Connect conductor wire end by touch line, take out line, looking for the methods such as line to obtain the connecting wire other end and this connecting wire institute connecting resistance at this should
Become the corresponding relation of instrument measurement port numbering；3) correspondence of resistance strain gauge measurement port numbering and strain value measured by this port
Relation.Structural strain measuring point numbering and the strain measurement value of this measuring point can be obtained using above 3 corresponding relations.
During traditional experiment, structure measuring point number is typically less, and above corresponding relation is very simple, experimenter or even energy
Remember this relation, so just can rapidly obtain structure somewhere in experimentation to strain the resistance strain gauge port corresponding to measuring point
Number and this port numbers measured by strain value, thus obtaining the strain measurement value of structure measuring point at this.But based on country to leading
Bullet, the development increase in demand of heavy launcher housing large scale structure, the medium-and-large-sized structure of engineering problem widely use and engineering
The characteristic such as problem is increasingly sophisticated, in present structural strain measurement experiment, strain measuring point number also greatly increases, often up to hundreds of,
The connecting wire that this results between resistance strain gage and resistance strain gauge measurement port is excessively answered so that straining measuring point with resistance
The corresponding relation becoming between instrument port is extremely complex, is touched line, is smoked line, looks for the methods such as line to obtain connecting wire two ends by traditional
Resistance strain gage and resistance strain gauge port corresponding relation are not real and efficient, and the risk of this error in operation is very
Greatly.
In sum, it is necessary at present to propose the strain measurement wire that a kind of two ends carry two-dimentional code labeling, thus simplifying
According to structural strain measuring point numbering obtain this at strain measurement value, according to measured by resistance strain gauge measurement port and this port
Strain value obtains the operating process of this port corresponding structural strain measuring point numbering, improve such strain measurement experiment efficiency and
Accuracy.
