Sažetak
Predlaže se jedan novi model mešovitog podmazivanja u okviru metode redukcije dimenzionalnosti ili MDR-a. Kod njega se dinamički podmazani kontakt valjanja između grubih povšrina simulira na osnovu rezultata elastohidrodinamičkog podmazivanja (EHL-a). Da bismo objasnili prekid dodatnog graničnog sloja na lokalnoj mikrokontaktnoj površi uvodimo i dopunski kriterijum. Upoređenja radi, postavlja se testirna oprema od dva diska radi merenja električnog otpora između dve podmazane valjane površine pod različitim normalnim silama, rotacionim brzinama i temperaturama. Ispitali smo verovatnoću proboja graničnog sloja i za eksperiment i za simulaciju i utvrdili dobro slaganje.
