Multidimensional energy harvesting and broadband work are integrated into one structure through the combined action of oblique angle, mass blocks, and piezoelectric beam. The mechanical model of the beam is established for theoretical analysis; the output characteristics of the structure are analyzed by finite element simulation; a piezoelectric energy harvesting experimental bench is built. The results show that: The structure has a wider harvesting band, multi-order resonant frequency, multi-dimensional energy harvesting, and higher output voltage and power than the traditional cantilever structures. The output performance of the specimens with 45\u00b0 oblique angle, 5 g:5 g mass ratio, and 0.2 mm thickness of piezoelectric substrate is good in the frequency band of 10~40 Hz. When the excitation frequency is 28 Hz, the output voltage of the sextuple array structure reaches 19.20 V and the output power reaches 7.37 mW. The field experiments show that the harvester array can meet the requirements of providing auxiliary energy for wireless sensor nodes in the process of active vibration control of stiffened plates.<\/jats:p>","DOI":"10.3390\/s22186720","type":"journal-article","created":{"date-parts":[[2022,9,8]],"date-time":"2022-09-08T04:18:32Z","timestamp":1662610712000},"page":"6720","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Research on the Characteristics and Application of Two-Degree-of-Freedom Diagonal Beam Piezoelectric Vibration Energy Harvester"],"prefix":"10.3390","volume":"22","author":[{"given":"Tianbing","family":"Ma","sequence":"first","affiliation":[{"name":"State Key Laboratory of Mining Response and Disaster Prevention and Control in Deep Coal Mines, Anhui University of Science and Technology, Huainan 232001, China"},{"name":"College of Mechanical Engineering, Anhui University of Science and Technology, Huainan 232001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5305-7604","authenticated-orcid":false,"given":"Kaiheng","family":"Sun","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mining Response and Disaster Prevention and Control in Deep Coal Mines, Anhui University of Science and Technology, Huainan 232001, China"},{"name":"College of Mechanical Engineering, Anhui University of Science and Technology, Huainan 232001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shisheng","family":"Jia","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mining Response and Disaster Prevention and Control in Deep Coal Mines, Anhui University of Science and Technology, Huainan 232001, China"},{"name":"College of Mechanical Engineering, Anhui University of Science and Technology, Huainan 232001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5975-3195","authenticated-orcid":false,"given":"Fei","family":"Du","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Anhui University of Science and Technology, Huainan 232001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhihao","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mining Response and Disaster Prevention and Control in Deep Coal Mines, Anhui University of Science and Technology, Huainan 232001, China"},{"name":"College of Mechanical Engineering, Anhui University of Science and Technology, Huainan 232001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3848","DOI":"10.1016\/j.istruc.2021.06.061","article-title":"Progressive-models method for evaluating interactive stability of steel box girders for bridges-Extension of progressive collapse method in ship structures","volume":"33","author":"Bai","year":"2021","journal-title":"Structures"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1350","DOI":"10.1016\/j.engfailanal.2021.105575","article-title":"Buckling fatigue behavior of 2A97 Al-Li alloy stiffened panels under shear loading","volume":"128","author":"Peng","year":"2021","journal-title":"Eng.
