Summary
Dynamic models are widely used for simulating friction phenomena, however, the examination of the models is often limited to numerical simulations. In this paper, new models based on the Generalized Maxwell-Slip (GMS) model − the SGMS-Coulomb and the SGMS-Stribeck model − are examined. These models form a surprisingly interesting phase space, even with the use of only a single internal state variable. We apply these models through a simple mechanical example and perform phase space analyses. We present different types of discontinuities, special points, equilibria, and bifurcations, which may remain hidden if we rely solely on numerical simulations. The results of the study indicate further, deeper research work in the field of the family of GMS models.
