Self-excited forced vibrations with solid friction of a block lying on a moving surface of nonconstant speed are treated theoretically, using an averaging method, in the case of the cubic friction-velocity characteristic curve. First approximate solutions of the harmonic vibration types of [ I ] and [ II ] can occur in the cubic case, as well as the linear one. In the present report, we studied several features of steady-state vibrations and stabilities of the harmonic solutions of these types. Furthermore, the behavior of a block in the vicinity of singular points is shown, using various trajectories in the R-ε plane, and vibrations of the nonharmonic type, accompanied by the occurrence of limit cycles, are studied. Finally, these first approximate solutions calculated by the averaging method are compared with the ones obtained through the use of the precise piecewise linear approximation method.
