Abstrakt
Anisotropic friction can produce friction force which is not collinear with a sliding
direction. How much friction deviates from a sliding direction is described with a so-called
sliding potential or equivalently a sliding rule. A sliding potential is often described with an
ellipse or a superellipse. In this paper we propose an oval curve which provides piecewise continuous
mathematical description for a sliding rule and fits better to the experimental results
than a typical superepllipse. For an exemplary mechanical system it is shown, that an anisotropic
sliding potential can lead to an unstable equilibrium position in the system. Furthermore,
for what parameters the unstable equilibrium occurs differs between sliding potential models.
We have tested four different geometrical models of sliding potential in this regard.
