Model and Experiment Researches of the Bimorph Cantilevered Vibration Energy Harvester
摘要
Abstract
For the mass effects of the cantilevered piezoelectric vibration energy harvester(PVEH),a modified lumped-parameter model,which takes into account the effects of the tip mass on the vibration amplitude,are derived by considering the amplitude correction coefficient when the bimorph cantilevered PVEH is excited by a harmonic vibration. The model parameters are identified with the impedance analysis and admittance circle analysis methods, and the electromechanical transferring functions of the PVEH are also derived. Finally,the experimental system of the PVEH is set up;and the experimental results are good agreement with the theoretical simulation results,which testifies the validity of the modified model proposed in this paper.关键词
