The stress analysis resistance strain gauge possesses the characteristics of novel and unique appearance, small size and high qualified rate, and can reduce production cost and solve the problem of paster limitation.
Description
Technical field
The utility model 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 made up 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.
Utility model content
Technical assignment of the present utility model 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 one 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 utility model solves the technical scheme that its technical matters adopts: 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.
A kind of stress analysis of the present utility model with strain ga(u)ge compared to the prior art, there is following outstanding beneficial effect: the utility model size is little, can solve the limited difficult problem of testing element paster area; This strainometer appearance design uniqueness, can weld after first lamination, has improved the features such as production qualification rate.
