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.","PeriodicalId":50451,"journal":{"name":"Ferroelectrics Letters Section","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135482616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
