摘要

本文介绍了一种高效风能收集装置的设计。该装置可以利用压电薄膜的有效振动作用，将随机风能转化为电能，为低功耗无线传感器网络等供电。采用有限元法对矩形、梯形和三角形PVDF悬臂梁的静态特性进行了分析，结果表明，三角形压电悬臂梁的输出电压特性最优。数值分析了几何参数和材料参数对压电梁输出电压的影响。给出了不同风速与输出电压的关系，为设计提供了依据。

Design and simulation of wind power generation device by PVDF piezoelectric thin film

This work presented a design of an efficient wind energy collection device. This device can transform random wind energy into electrical energy by an effective vibration action of the piezoelectric film, which can supply the power for the low-power wireless sensor networks and so on. The static characteristics of rectangular, trapezoidal and triangular PVDF cantilever beams were analyzed by finite element method, and the results showed that the triangular piezoelectric cantilever beam had the optimal characteristics for the output voltage. The effects of the geometrical and material parameters on the output voltage of the piezoelectric beam were analyzed numerically. The relationship between the different wind speed and the output voltage was given for the design.
