The research presents the strength calculation for the bearing structure of an open wagon with consideration of the engineering solutions proposed. It was found that the maximum equivalent stresses appeared in the bottom section of the centre sill behind the back support; they amounted to about 315 MPa and did not exceed the allowable values. The maximum displacements were detected in the middle section of the centre sill and amounted to 9.6 mm. The maximum deformations were 1.17 \u00d7 10\u22122. The research also presents the strength calculation for a weld joint in the maximum loaded zones of the bearing structure of an open wagon and gives the results of a modal analysis of the bearing structure of the improved open wagon. It was found that the critical oscillation frequencies did not exceed the allowable values. The results of the research may be useful for those who are concerned about designing innovative rolling stock units and improving the operational efficiency of railway transport.<\/jats:p>","DOI":"10.3390\/ma14123420","type":"journal-article","created":{"date-parts":[[2021,6,20]],"date-time":"2021-06-20T22:00:02Z","timestamp":1624226402000},"page":"3420","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Research into the Strength of an Open Wagon with Double Sidewalls Filled with Aluminium Foam"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2387-9946","authenticated-orcid":false,"given":"Oleksij","family":"Fomin","sequence":"first","affiliation":[{"name":"Department of Cars and Carriage Facilities, State University of Infrastructure and Technologies, Kyrylivska Str., 9, 04071 Kyiv, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mykola","family":"Gorbunov","sequence":"additional","affiliation":[{"name":"Department of Railway, Automobile Transport and Handling Machines, Volodymyr Dahl East Ukrainian National University, Central Avenue 59a, 93400 Sewerodonetsk, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3928-0567","authenticated-orcid":false,"given":"Juraj","family":"Gerlici","sequence":"additional","affiliation":[{"name":"Department of Transport and Handling Machines, University of Zilina, Univerzitna 1, 010 26 Zilina, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Glib","family":"Vatulia","sequence":"additional","affiliation":[{"name":"Department of Structural Mechanics and Hydraulics, Ukrainian State University of Railway Transport, Feuerbach Square 7, 61050 Kharkiv, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alyona","family":"Lovska","sequence":"additional","affiliation":[{"name":"Department of Wagon Engineering and Product Quality, Ukrainian State University of Railway Transport, Feuerbach Square 7, 61050 Kharkiv, Ukraine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3775-6288","authenticated-orcid":false,"given":"Kateryna","family":"Kravchenko","sequence":"additional","affiliation":[{"name":"Department of Transport and Handling Machines, University of Zilina, Univerzitna 1, 010 26 Zilina, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"00030","DOI":"10.1051\/matecconf\/201823500030","article-title":"Design of a new railway wagon for intermodal transport with the adaptable loading platform","volume":"235","year":"2018","journal-title":"MATEC Web Conf."},{"key":"ref_2","unstructured":"Zhong, Y.-G., Zhan, Y., and Zhao, G.
