Abstract

AbstractThis paper proposes a Dual-Cylinder Piezoelectric Energy Harvester (DC-PEH). The cylinders generate vortex-induced vibration under the action of wind, driving the cantilever beam to deform. During the vibration process, the cantilever beam produces two types of bending modes, namely U-shaped vibration and S-shaped vibration. According to the experimental results, as the wind speed increases, the output power of the DC-PEH first increases and then decreases. When the diameter of the cylinders at both ends of the DC-PEH is 36 mm and the wind speed is 4.3 m/s, the output power can reach 7.812 mW.Keywords: Piezoelectric energy harvestingfluid energyvortex-inducedmultiple vibrations Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by the Shandong Provincial Natural Science Foundation (ZR2022ME053, ZR2021QF092), The Youth Innovation Team Development Program of Shandong Provincial Higher Education Institutions (Grant No. 2022KJ234), National Natural Science Foundation of China (No.51975303) and Shandong Provincial Key Laboratory of Precision Manufacturing and Nontraditional Machining.

一种利用风能的双缸压电能量收集器

摘要提出了一种双缸压电能量采集器(DC-PEH)。气缸在风的作用下产生涡激振动，驱动悬臂梁变形。在振动过程中，悬臂梁产生两种弯曲模式，即u型振动和s型振动。实验结果表明，随着风速的增大，DC-PEH的输出功率先增大后减小。当DC-PEH两端气缸直径为36 mm，风速为4.3 m/s时，输出功率可达7.812 mW。关键词:压电能量收集流体能量涡激多重振动披露声明作者未报告潜在利益冲突。项目资助:山东省自然科学基金项目(ZR2022ME053, ZR2021QF092)，山东省高校青年创新团队发展计划项目(批准号:2022KJ234)，国家自然科学基金项目(No.51975303)，山东省精密制造与非传统加工重点实验室。
