(PTT model) predicts that friction increases nearly logarithmically with speed because at higher speeds there is less time per unit cell for thermally-assisted hopping [6-8], a trend observed in several atomic force microscope (AFM) experiments[2]. Atomic ... WebThe LuGre model is a dynamic model which can capture the dynamic behaviors of the contacting surfaces [3], where friction is related to the deflection of bristles. In this model, the rate-dependent friction phenomenon and the Stribeck effect are all considered. The LuGre model is given by (1.11)
