| Abstract: | The theoretical model for measuring the vibration parameters through measuring strains with PVDF piezoelectric films and the equivalent model and sensing equations for PVDF piezoelectric films sensitive component for vibration parameters are explored, and the composition of signal processing systems are presented and also the method of estimating the modal coordinates and displacement response. The results compared with the non-contact vibration-displacement measuring instrument are presented. |
