VIBRATION MODE RECONSTRUCTION OF A THIN PLATE BY USING SHAPED PVDF SENSORS

摘要

We developed a novel vibration measurement method using distributed sensors for detecting vibration of flexible structures. In this study, being performed precise simulations and experiments, we obtained quantitatively good agreements between experiments and theoretical calculations. The errors in the case of omitting higher order PVDF shapes are also predicted. Both experimentally and theoretically, we have confirmed the efficacy of the method based on our theory, namely the Fourier series shape affixing method, in which PVDF sensors are used and strain distributions are multiplied by weights and integrated.
