Abstract

This article establishes a mathematical measurement model for calibrating adhesive resistance strain gauges based on the definition of strain values. Through experimental research, the influence of tensile coaxiality on strain measurement results was analyzed, and two different eccentric forms of tensile morphology were discovered in the experiment. A metal flat strip tensile morphology monitoring method based on three-point angle monitoring method was proposed. In addition, combined with finite element numerical simulation, the influence of lateral force on the measurement results was studied. The results showed that when the axial load was loaded to 10%, there was an approximately linear relationship between the axial strain of the metal strip and the tensile load. The research results provide theoretical basis and technical support for strain gauge calibration and optimization of testing methods.
