Using the same encapsulated piezoelectric stack, an inertial-type actuator and a frame-type actuator are constructed for performance comparison. The experimental results are also used to validate the recently established actuator models, whilst the mechanical and piezoelectrical parameters of the models are experimentally identified. The performance of the actuators is described by the transmitted force(s) and input power flow from the actuators to the base structure with reference to the same electrical input voltage to the stack. The validation is deemed successful due to the strong agreement observed between the measured and predicted actuator performances. Additionally, it is discovered that the frame-type actuator has the capacity to produce significantly higher transmitted forces and input power flow to the base structure compared to the inertial-type actuator. The mechanism underlying the performance disparity between these two types of actuators is also examined. This paper clarifies the mechanism, shedding light on the design and optimization of piezoelectric actuators.<\/jats:p>","DOI":"10.3390\/s24123950","type":"journal-article","created":{"date-parts":[[2024,6,19]],"date-time":"2024-06-19T08:06:06Z","timestamp":1718784366000},"page":"3950","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Experimental Validation of Two Types of Force Actuators: A Performance Comparison"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3507-3360","authenticated-orcid":false,"given":"Xishan","family":"Jiang","sequence":"first","affiliation":[{"name":"Department of Instrument Science and Engineering, Zhejiang University, Hangzhou 310027, China"}]},{"given":"Ning","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Instrument Science and Engineering, Zhejiang University, Hangzhou 310027, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9584-5692","authenticated-orcid":false,"given":"Jing","family":"Zheng","sequence":"additional","affiliation":[{"name":"Department of Instrument Science and Engineering, Zhejiang University, Hangzhou 310027, China"}]},{"given":"Jie","family":"Pan","sequence":"additional","affiliation":[{"name":"Department of Instrument Science and Engineering, Zhejiang University, Hangzhou 310027, China"},{"name":"Department of Mechanical Engineering, University of Western Australia, Crawley, WA 6009, Australia"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"182","DOI":"10.5772\/59099","article-title":"Recent advances in the control of piezoelectric actuators","volume":"11","author":"Chi","year":"2014","journal-title":"Int.
