A model of dynamic effect during low amplitude oscillations of surfaces comparable with the pre
liminary displacement and the first acts of sleep under the oscillating tangential loading of the contact is
developed. Solving a system of differential force balance equations has yielded the main characteristics of the
process of the dynamics of a nominally stationary contact depending on the governing parameters of the sys
tem. Regularities of the friction characteristic at low sliding velocity are determined with allowance for the
preliminary displacement phenomenon, the Stribeck effect, as well as the parameter of the plasticity and vis
cosity of friction. The model allows one tracing the evolution of relative displacements and slip velocities, cal
culating phase diagrams, as well as deriving the friction characteristic and real slip amplitudes typical of the
mixed friction mode and low amplitude fretting.
