These geometric structure parameters include the difference between the inner and outer radius, thickness, and equivalent radius. The magnetic field distribution around the probe is simulated and analyzed under different parameters, and the detection performance of the probe is judged in combination with the change rate of the magnetic field around the probe coil. The simulation results show that at a closer position, increasing the difference between the inner and outer radii, reducing the thickness, and reducing the equivalent radius are beneficial to improve the resolution of the probe coil. At a far position, reducing the difference between the inner and outer radii, increasing the thickness, and reducing the equivalent radius are beneficial to improve the resolution of the probe coil. At the same time, the accuracy of the simulation data is verified by comparing the theoretical values with the simulated values under different conditions. Therefore, the obtained conclusions can provide a reference and basis for the optimal design of the probe structure.<\/jats:p>","DOI":"10.3390\/s23146610","type":"journal-article","created":{"date-parts":[[2023,7,24]],"date-time":"2023-07-24T03:03:25Z","timestamp":1690167805000},"page":"6610","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Research on the Influence of Geometric Structure Parameters of Eddy Current Testing Probe on Sensor Resolution"],"prefix":"10.3390","volume":"23","author":[{"given":"Mengmeng","family":"Song","sequence":"first","affiliation":[{"name":"College of Information, Mechanical and Electrical Engineering, Ningde Normal University, Ningde 352000, China"}]},{"given":"Mengwei","family":"Li","sequence":"additional","affiliation":[{"name":"College of Information, Mechanical and Electrical Engineering, Ningde Normal University, Ningde 352000, China"},{"name":"College of Mechanical and Electrical Engineering, Fujian Agriculture and Forestry University, Fuzhou 350000, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2978-4131","authenticated-orcid":false,"given":"Shungen","family":"Xiao","sequence":"additional","affiliation":[{"name":"College of Information, Mechanical and Electrical Engineering, Ningde Normal University, Ningde 352000, China"},{"name":"College of Mechanical and Electrical Engineering, Fujian Agriculture and Forestry University, Fuzhou 350000, China"}]},{"given":"Jihua","family":"Ren","sequence":"additional","affiliation":[{"name":"Dongguan Xinghuo Gear Co., Ltd., Dongguan 523000, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,22]]},"reference":[{"key":"ref_1","unstructured":"Ding, S., and Liu, F.
