Original abstract
In this study, the effect of high slide-roll ratio on thermal elastohydrodynamic lubrication in line contacts is explored numerically. The surface dimple produced by the heat transportation of the surface is explained. Furthermore, the deformation of the surface waviness under zero entrainment velocity is analyzed. The results show that, under high slide-roll ratios, similar to those under rolling or rolling–sliding conditions, the deformation of the surface waviness depends on the slide-roll ratio and the wavelength of the harmonic waviness.

V této studii je numericky studován vliv velkého prokluzu na chování elastohydrodynamicky mazaného kontaktu. Deformace třecího povrchu v důsledku tepelného ovlivnění je vysvětlena. Kromě toho, je analyzována deformace povrchového zvlnění při nulovém vstupní rychlosti. Výsledky ukazují že, deformace povrchu závisí na prokluzu a vlnové délce harmonické nerovnosti.
