悬臂梁压电发电机的基频谐振频率与功率
First-order resonance frequency and power output of a cantilever piezoelectric generator
摘要
Abstract
In order to eliminate the errors caused by the length of tip mass of Roundy model on the cantilever vibration piezoelectric generator, under the premise of considering the length of tip mass, this paper takes the deflection of cantilever where mass center of tip mass acts upon as degree of freedom, and establishes the theoretical model and derives the equation of the first order resonant frequency , output voltage and output power of the cantilever vibration piezoelectric generator. The proposed model was compared with Roundy model by numerical simulation, and the result shows when the length of tip mass is close to the length of cantilever, the deviation between the proposed model and Roundy model is larger, and when the difference between length of tip mass and length of cantilever is bigger, the deviation between the proposed model and Roundy model is smaller. The experimental results show that the errors between the proposed model and experiment is less than Roundy model, the accuracy of the proposed model is better than Roundy model.关键词
