WebMar 24, 2010 · This paper presents a study of the spinning influence on film thickness and friction in EHL circular contacts under isothermal and fully flooded conditions. Pressure and film thickness profiles are computed with an original full-system finite element approach. Friction was thereafter investigated with the help of a classical Ree–Eyring model to … WebMar 23, 2015 · In the third case the target ball is placed on a plane with friction (plane B in figure 9(B)). The target ball departs from the collision sliding on the plane, but along the motion kinetic friction produces a decrease in linear velocity and an increase in rotational velocity, until the pure rolling condition is reached.
