Abstract
The problem of low efficiency of vibration energy collection in the environment is the focus of the research on piezoelectric power generation technology.In order to improve the collection efficiency of the vibration energy in the environment,the piezoelectric power generation technology for multi-direction collecting environment vibration energy is studied.First,the mathematical model of the piezoelectric cantilever is built by the basic theory of the piezoelectric power generation technology,and the vibration mechanics analysis is carried out.Then,the piezoelectric cantilever is analyzed using ANSYS finite element simulation,and the structure is optimized so that the natural frequency of the vibration frequency is consistent with the environment.And finally,the multi-direction piezoelectric device is developed,and its theoretical analysis and experimental testing are finished.The experimental results show that the multi-direction vibration of piezoelectric power generation key technologies can effectively improve the collection efficiency of vibration energy.关键词
