Study of Eliminating Calculation Errors in Large-Strain Measurement with Strain Gauges

Abstract:

Resistance strain gauge is common used in strain measurement, particularly in small elastic strain measurement, it has many advantages. However when the measured strain increases, the output nonlinearity of the Wheatstone bridge will become obvious; in this paper the nonlinearity error of the output in large-strain measurement is analyzed, and based on this a mathematical algorithm for nonlinearity compensation is proposed; finally the effect of the algorithm for nonlinearity compensation is proved by theoretical research and experimental treatment.
