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