The model of a double-belt friction oscillator is proposed, which exhibits multiple discontinuity boundaries in the phase space. The system consists of a visco-elastic oscillator dragged by two different rough supports moving with constant driving velocities. The evolution of steady-state attractors as the discontinuity parameters are varied is described. The presence of multiple discontinuity boundaries leads to nonsmooth responses which are studied here by means of analytical and numerical tools.
