Abstract

The static force of friction between two bodies moving in a random potential and coupled by a randomly oscillating bond is studied as a function of the oscillation amplitude. It is shown that this dependence can be used for reconstructing the spectral density of the random potential. These results provide a basis for the experimental determination of the characteristic scale of friction processes from the law of friction of oscillating tribosystems.
