英文摘要：

According to the dynamics structure of the cantilever beam, a voltage prediction model of Gafenol cantilever beam vibration energy harvester was presented in this paper. The proposed model was based on the spring-damper-mass model, giant magnetostrietive material linear constitutive equation and Faraday＇ s law of electromagnetic induction. Then a simulation system was established by using the given model. Finally, the proposed model is verified by experiments. The simulation results are close to the experimental data. The given model can accurately predict the output voltage of the Galfenol cantilever beam vibration energy harvester.
