Abstract

为了提高压电悬臂梁发电能力，本文提出了一种将压电悬臂梁银电极分段发电的方法，首先确定了压电振子分段的方式，并对分段方式进行了理论分析，得出每段电极输出电压的表达式。然后进行了压电悬臂梁不同分段发电能力测试，进行了三种不同分段方式的测试，得出最佳分配比例为1:2:3，最大发电量达到15 V，为压电悬臂梁发电优化设计提供了理论依据和技术参考。 In order to improve the power generation capacity of a piezoelectric cantilever beam, a method of segmented power generation by the silver electrode of a piezoelectric cantilever beam is proposed in this paper. First, the sectional mode of the piezoelectric vibrator is determined, and the sectional mode is theoretically analyzed, and the expression of the output voltage of each section is obtained. Then the power generation capacity of three different sections of the piezoelectric cantilever beam is tested. The optimum distribution ratio is 1:2:3, and the maximum power generation capacity is 15 V. It provides a theoretical basis and technical reference for the optimal design of a piezoelectric cantilever beam.
