3917 ピエゾケーブルセンサーを用いたひずみ検出(S17-3 強度・変形・ひずみ評価,S17 実験力学における最近の展開)

抄録

Piezoelectric film is noticed as a sensor for the monitoring recently. Because, amplifier and power are unnecessarily. In this study, the strain measurement which uses the piezo cable a built-in piezoelectric film was tried. In the experiment, in order to know the tensile characteristic of a piezo cable simple substance first, the static tensile examination was performed. And cyclic tensile load applied to the piezo cable, various influences which it causes to output voltage were inspected. Especially, it changed cable length, load frequency, load amplitude. As a result, I understood that the output voltage of a piezo cable increased in proportion to the displacement amplitude. Therefore, the possibility was discovered where it can utilize the piezo cable as the strain sensor.
