论文摘要
压电振动能量收割机引起了很多关注，因为它有可能取代当前流行的电池并提供可持续的电源。许多研究人员提出了提高压电能量收获者（如带宽，工作频率和输出性能）的性能的方法。在此贡献中，我们提出了使用弹性扩展来调整压电能量收割机的性能的方法。得出和分析了所提出的设备的数学模型。进行数值模拟是为了研究派生参数的影响，例如长度比λ_l，弯曲刚度比λ_b和线密度比λ_m。结果表明，弹性扩展确实改变了提议的设备的运动，并有助于调整压电能量收割机的性能。
Piezoelectric vibration energy harvesters have attracted much attention due to its potential to replace currently popular batteries and to provide an sustainable power sources. Many researchers have proposed ways to increase the performance of piezoelectric energy harvesters like bandwidth, working frequency and output performance. Here in this contribution, we propose the method of using elastic extensions to tune the performance of a piezoelectric energy harvester. Mathematical model of the proposed device is derived and analyzed. Numerical simulations are done to investigate the influences of the derived parameters, like length ratio λ_l , bending stiffness ratio λ_B , and line density ratio λ_m . Results show that the elastic extension does change the motion of the proposed device and help tune the performance of piezoelectric energy harvesters.
