These wheels are increasingly being used in combined transport applications, where they are installed in various bogie configurations and subjected to different operational environments. However, due to the unique characteristics of reduced-diameter wheels, their lifespan has been scarcely studied. To accurately build this model, an in-depth investigation of the rolling phenomenon was required, addressing key issues in the track\u2013vehicle interaction and establishing relationships between these factors. After constructing the rail\u2013wheel interaction model, it was applied to calculate the lifespan of wheels with standard, medium, and reduced diameters under identical conditions for comparison. This approach makes it possible to determine the lifespan of reduced-diameter wheels relative to standard ones, as well as to observe how lifespan changes with wheel diameter, and it is observed how lifespan diminishes non-linearly with decreasing diameters. The underlying reasons for this variation are explained through a comprehensive understanding of the rolling phenomenon, enabled by the full analysis.<\/jats:p>","DOI":"10.3390\/a17100437","type":"journal-article","created":{"date-parts":[[2024,10,1]],"date-time":"2024-10-01T05:26:33Z","timestamp":1727760393000},"page":"437","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Theoretical Study of the Wear of a Reduced-Diameter Wheel for Freight Wagons, Based on Its Diameter"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7876-3177","authenticated-orcid":false,"given":"David S.","family":"Pellicer","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, University of Zaragoza, 50018 Zaragoza, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5857-8003","authenticated-orcid":false,"given":"Emilio","family":"Larrod\u00e9","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, University of Zaragoza, 50018 Zaragoza, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Pellicer, D.S., and Larrod\u00e9, E.
