Abstract
The invention discloses a resistance strain gauge for stress analysis and belongs to strain gauges. The structure of the strain gauge comprises a marking base and a strain gauge body. The strain gauge body comprises a first layer of strain gauge sheet, a second layer of strain gauge sheet and a third layer of strain gauge sheet. A sensitive grid is arranged on the upper portions of the first layer of strain gauge sheet, the second layer of strain gauge sheet and the third layer of strain gauge sheet respectively. A protection layer is arranged on the upper portion of the sensitive grid of the third layer of strain gauge sheet. Wire grid axes of the sensitive grids on the upper portions of the first layer of strain gauge sheet, the second layer of strain gauge sheet and the third layer of strain gauge sheet are distributed at 45 degrees, 135 degrees and 90 degrees, welding discs of the sensitive grids are distributed at the same angle, leads are arranged on each of the welding discs, and the whole strain gauge outline dimension is smaller than 3mm*3mm. The strain gauge has the advantages of being novel and unique in appearance, small in size, high in yield and capable of reducing production costs and solving the problem of the limitation of patches.
Description
Technical field
The present invention relates to a kind of strainometer, especially a kind of stress analysis strain ga(u)ge.
Background technology
Stress analysis is mainly done stress analysis, is measured use with strainometer, and along with scientific and technological development, stress analysis is widely used in industry-by-industry with strainometer.General stress analysis is comprised of 3 angled sensitive grids of axes intersect with the sensitive grid region of strainometer, can measure the stress of three directions, and area is generally larger.At present conventional stress analysis is counted three axle lamination types with strain, complex manufacturing technology, and qualification rate is lower.
This type of common strainometer size is generally greater than 3mm * 3mm at present.And for the limited testing element in some paster region, harsher to the dimensional requirement of this type of strainometer, the stress analysis of common size is difficult to meet the demands with strainometer.
At present, the solution also not had.
Summary of the invention
Technical assignment of the present invention is to provide a kind of stress analysis strain ga(u)ge for above-mentioned deficiency of the prior art, it is novel unique that this kind of stress analysis has strainometer outward appearance with strain ga(u)ge, size is little but qualification rate is high, can reduce production costs and solve the limited difficult problem of paster.
The technical solution adopted for the present invention to solve the technical problems is: it comprises marking substrates and strainometer body, described strainometer body is arranged on the top of marking substrates, described strainometer body comprises ground floor strainometer sheet, second layer strainometer sheet and the 3rd ply strain meter sheet, described ground floor strainometer sheet, second layer strainometer sheet and the 3rd ply strain meter sheet set gradually from top to bottom, described ground floor strainometer sheet, the top of second layer strainometer sheet and the 3rd ply strain meter sheet is respectively arranged with sensitive grid, the top of the sensitive grid of the 3rd ply strain meter sheet is provided with protective seam, ground floor strainometer sheet, the wire grid of the sensitive grid that second layer strainometer sheet and the 3rd ply strain meter sheet top arrange is axially respectively 45 °, 135 °, 90 ° of distributions, ground floor strainometer sheet, the pad of the sensitive grid that second layer strainometer sheet and the 3rd ply strain meter sheet top arrange is same angular distribution, on each pad, be respectively arranged with lead-in wire, the physical dimension of whole strainometer is less than 3mm * 3mm.
Square or rectangular is counted in whole strain.
The physical dimension of described marking substrates is 2.5mm * 2.7mm.
With strain ga(u)ge compared to the prior art a kind of stress analysis of the present invention, has following outstanding beneficial effect: size of the present invention is little, can solve the limited difficult problem of testing element paster area; This strainometer appearance design is unique, can after first lamination, weld, and has improved the features such as production qualification rate.
