【 摘 要 】

For harvesting the low-frequency and weak-amplitude vibration energy in real environment, a two-degrees-of-freedom bistable piezoelectric vibration generator is designed. And the dynamic model of the piezoelectric vibration generator system is established. And the influence of the external excitation on the output characteristics of the two-degree-freedom piezoelectric vibration generator system is simulated and analyzed. The results show that the two-degrees-of-freedom bistable piezoelectric vibration generator would do better in harvesting and converting for the low-frequency and weak-amplitude vibration energy.
