Research on dynamic strain testing technology based on flexible piezoelectric element

Abstract

This paper first studies the internal mechanism of strain measurement of flexible piezoelectric elements through theoretical analysis. Then, based on this, the flexible piezoelectric sensor is designed in form, and the error of the flexible piezoelectric sensor is compensated. Finally, the flexible piezoelectric sensor and the strain gauge were compared and tested, and a new test method suitable for the dynamic strain parameter test of flight test was obtained.
