Abstract
In order to effectively use the piezoelectric cantilever generator to collect the ambient vibration energy, it is necessary to study the influence of the structural parameters on the operating frequency, output voltage and output power of the piezoelectric cantilever beam. Firstly, the influence of the length, the thickness and the width ratio of the substrate and the piezoelectric ceramic on the output voltage and natural frequency of the piezoelectric cantilever beam are analyzed. Then, the influence of the output voltage and the quality of the mass block on the output power of the trapezoidal piezoelectric cantilever beam under harmonic excitation is analyzed. Finally, the influence of the external load resistance on the output power of the piezoelectric generator and the influence of the mass block on the internal resistance of the piezoelectric cantilever beam are studied. The results show that the triangular piezoelectric ceramic piece has the strongest power generation performance, followed by the trapezoidal piezoelectric ceramic piece, the rectangular piezoelectric ceramic piece is worst under the condition of the same length, thickness and upper width of the substrate and the piezoelectric ceramic piece, and there is an optimal length and thickness of the piezoelectric ceramic piece; The shape of the substrate has a greater influence on the resonant frequency of the piezoelectric energy collector than that of the piezoelectric ceramic;Increasing the quality of the mass block can significantly improve the output power of the piezoelectric energy collector and improve its internal resistance.
