When designing rolling bearings, great efforts are made to optimise bearing geometries. However, under unfavourable operating conditions, edge pressures caused by the truncation of contact ellipses cannot be completely ruled out. However, such edge pressures cannot be evaluated in a physically sound manner with the established bearing design methods, which are based on elastic contact calculations. Therefore, in this work, an approach has been\ndeveloped to evaluate edge pressures based on simulations of repeatedly rolled-over elastic-plastic contacts. The approach is based on semi-analytical methods (SAM), which are based on half-space theory. A fast, partially transient approximation method for the simulation of repeatedly rolled-over elasto-plastic contacts has been developed. Furthermore, the characteristics of edge pressures or contacts with truncated contact ellipses were investigated\nand the suitability of the SAM for their simulation was evaluated. Finally, the evaluation approach for rolled-over contacts with edge pressures was formulated and its potential as well as existing challenges and possible solutions were discussed.<\/p>","protected":false},"excerpt":{"rendered":"
Bei der Auslegung von W\u00e4lzlagern werden gro\u00dfe Anstrengungen zur Optimierung der Lagergeometrien unternommen. Dennoch lassen sich, bei ung\u00fcnstigen Betriebsbedingungen, Kantenpressungen durch das Abschneiden von Kontaktellipsen nicht vollst\u00e4ndig ausschlie\u00dfen. Solche Kantenpressungen sind jedoch mit den etablierten Methoden der Lagerauslegung, die auf elastischer Kontaktberechnung basieren, nicht physikalisch fundiert bewertbar. Im Rahmen dieser Arbeit wurde deshalb ein Ansatz […]<\/p>\n","protected":false},"featured_media":4576,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[34],"product_tag":[],"class_list":{"0":"post-4575","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-fau-studien-aus-dem-maschinenbau","7":"has-post-title","8":"has-post-date","9":"has-post-category","10":"has-post-tag","11":"has-post-comment","12":"has-post-author","13":"","15":"first","16":"instock","17":"taxable","18":"shipping-taxable","19":"purchasable","20":"product-type-simple"},"acf":{"autor":"J\u00fcttner, Michael","orcid":"0000-0002-8910-0707","ror":"00f7hpc57","herausgeber":"","orcid_hrsg":"","rorhrsg":"","bearbeiter":"","sonstige_beteiligte_personen":"","untertitel":"","zusatz":"","jahr":"2024","zeitschrift":"","serie":"","serie_name":false,"serie_band":"","serie_jahr":"","serie_titel_band":"","vortrage":"","issn":"","isbn":"","isbn13":"978-3-96147-713-5","seiten":"xii, 162","sonstiges":"","band":433,"auflage":"","opus":"","dspace":"30492","e-isbn_pdf":"978-3-96147-714-2","doi":"https:\/\/doi.org\/10.25593\/978-3-96147-714-2","epub":"","e-isbn_epub":"","doi_epub":"","html":"","e-isbn_html":"","doi_html":"","e-isbn_reader":"","doi_reader":"","digibib":"","urn":"urn:nbn:de:101:1-2024020904022329822968","supplementary_material":"","sprache":["Deutsch"],"ausgabe":"Softcover","suche":" 9783961477135 9783961477142 ","lizenz":"BY-NC-4","bemerkung":""},"builder_content":"","_links":{"self":[{"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product\/4575","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/comments?post=4575"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/media\/4576"}],"wp:attachment":[{"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/media?parent=4575"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product_brand?post=4575"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product_cat?post=4575"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product_tag?post=4575"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
