STRANGE NONCHAOTIC ATTRACTORS AND COMPLICATED QUASI-PERIODIC CASCADES INDUCED BY BIFURCATIONS IN A DRY-FRICTION OSCILLATOR UNDER QUASI-PERIODIC EXCITATION

This paper explores the crossing bifurcation, switching-sliding and grazing-sliding bifurcations in a dry-friction oscillator on a moving belt under quasi-periodic excitation with two frequencies. We present a concrete method to approximate the largest Lyapunov exponent. By apply...
