    This work proposes an analytical model for the stick-slip friction of a solid mass on oiled surfaces. The dynamic friction was described as Fd = λAv, where λ is a parameter related to the surface conditions, A is the contact area and v is the sliding velocity. A mass-spring system with a dashpot with damping constant c (=λA) was used to determine the slip motions of the solids. The applicability of the model is examined by comparing the experimental slip displacements of rubber samples on oiled smooth glass surfaces. The model represents the important aspects of slip motions and suggested that an abrupt change in the acceleration force from positive to negative magnitudes was responsible for the unstable stick-slip phenomenon.
