Abstract EN
Mechanical vibrations have been an important sustainable energy source, and piezoelectric cantilevers operating at the resonant frequency are regarded as one of the effective mechanisms for converting vibration energy to electricity.
This paper focuses on model and experimental investigations of multiple attached masses on tuning a piezoelectric cantilever resonant frequency.
A discrete model is developed to estimate the resonant frequencies’ change of a cantilever caused by multiple masses’ distribution on it.
A mechanism consisted of a piezoelectric cantilever with a 0.3 g and a 0.6 g movable mass along it, respectively, is used to verify the accuracy of the proposed model experimentally.
And another mechanism including a piezoelectric cantilever with two 0.3 g attached masses on it is also measured in the designed experiment to verify the discrete model.
Meanwhile, the results from the second mechanism were compared with the results from the first one in which the single attached mass is 0.6 g.
Two mechanisms have wildly different frequency bandwidths and sensitivities although the total weight of attached masses is the same, 0.6 g.
The model and experimental results showed that frequency bandwidth and sensitivity of a piezoelectric cantilever beam can be adjusted effectively by changing the weight, location, and quantity of attached masses.
