摘要
为了提高拾振机构在微弱激励下的响应振幅,实现双稳态振动,采用变刚度拾振机构,通过AMESim建立一种变刚度双稳态电磁式振动发电机的完整模型,仿真结果表明,对比单一刚度拾振机构,增大了响应振幅,拓宽了频带,提高了发电功率。
In order to improve the response amplitude of the vibration harvester mechanism to the weak excitation and make the mechanism to realize bistable vibration, the variable stiffness vibration harvester mechanism was used. Based on AMESim a simulation model of variable stiffness electromagnetic vibration generator was established. The simulation results show that compared with the single stiffness vibration harvester mechanism, it can enhance the response amplitude, broaden the frequency band and improve the generated power.
