Vpliv razmerja med drsenjem in kotaljenjem na koeficient trenja v mazanem kontaktu med polimerom in jeklom : zaključna naloga Univerzitetnega študijskega programa I. stopnje Strojništvo - Razvojno raziskovalni programŽumer, AndražV tem delu smo raziskovali vpliv razmerja med drsenjem in kotaljenjem (SRR) na koeficient trenja. Obravnavali smo mazan kontakt med polimerno kroglico in jeklenim diskom. Za testiranje smo uporabili ... napravo Mini Traction Machine, ki je omogočala nastavitev poljubnih SRR in celo spreminjanje SRR tekom testa. Tako smo ves čas testa ohranjali ostale pogoje v kontaktu nespremenjene. Meritve testov smo numerično obdelali in rezultate predstavili v obliki diagramov. Ti so pokazali, da se v večini obratovalnih pogojev koeficient trenja povečuje, če povečujemo |SRR|. Izjema so bili testi, izvedenih pri nižji obremenitvi in negativnih vrednostih SRR. Pri njih se je koeficient trenja pri povečevanju |SRR| zmanjševal. Kontakt med polimerom in jeklom je izkazoval nižji koeficient trenja pri višji obremenitvi v primerjavi s testi opravljenimi pri nižji obremenitvi. Na podlagi tega predvidevamo, da se na jekleni površini tvori več polimernega filma pri višji obremenitvi, kakor pri nižji.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
