Abstract A nonlinear developed model for various PZT wind energy harvesters with arbitrary dimensions and location of electroceramics has been prepared. This model can describe unimorph and bimorph harvesters with different cantilever cross-sections attached to a tip body with different shapes. The system model has been validated with results reported in the literature. A set of parametric studies has been conducted to examine the influences of the cantilever shape in addition to the shape of the tip body. Furthermore, the impacts of load resistance and wind speed on the output power have been analyzed. The effects of number, position, and dimensions of piezoceramics on the harvester performance have also been investigated. It is found that by increasing the total area of electroceramics (including the length, width, or the number of PZT patches), the peak of the wind critical speed and the middle resistance range where the instability speed is very sensitive to the electrical load shifts toward the lower resistances. Moreover, several instrumental points to design efficient and affordable vibrating wind harvesters at low and high flows have been obtained.

考虑不同贴片、横截面和尖端体的 PZT 陶瓷流动能量收集器的建模与分析

摘要 建立了具有任意尺寸和位置的电陶瓷的各种PZT风能收集器的非线性开发模型。该模型可以描述具有不同悬臂横截面的单压电晶片和双压电晶片采集器，它们连接到具有不同形状的尖端主体。该系统模型已经通过文献中报告的结果进行了验证。已经进行了一组参数研究，以检查除尖端主体形状之外悬臂形状的影响。此外，还分析了负载电阻和风速对输出功率的影响。还研究了压电陶瓷的数量、位置和尺寸对收割机性能的影响。发现通过增加电瓷的总面积（包括长度、宽度或PZT贴片的数量），风临界速度的峰值和不稳定速度对电力负载非常敏感的中间电阻范围向较低的电阻移动。此外，已经获得了在低流量和高流量下设计高效且价格合理的振动风力收割机的几个重要点。
