摘要

本文首先通过理论分析，研究了柔性压电元件应变测量的内在机理。在此基础上，对柔性压电传感器进行了外形设计，并对柔性压电传感器的误差进行了补偿。最后，对柔性压电传感器和应变片进行了比较和测试，得出了一种适用于飞行试验动态应变参数测试的新测试方法。

Research on dynamic strain testing technology based on flexible piezoelectric element

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.
