“…As in the case of out-of-plane oscillations discussed in Ref. [33], there is qualitatively different behavior in the case of oscillation amplitudes smaller than some critical value (which in the present case is given by 0 0 y l  ) and in the case of large oscillation amplitudes.…”

The present paper is devoted to a theoretical analysis of sliding friction under the influence of in-plane oscillations perpendicular to the sliding direction. Contrary to previous studies of this mode of active control of friction, we consider the influence of the stiffness of the tribological contact in detail and show that the contact stiffness plays a central role for small oscillation amplitudes. In the present paper we consider the case of a displacement-controlled system, where the contact stiffness is small compared to the stiffness of the measuring system. It is shown that in this case the macroscopic coefficient of friction is a function of two dimensionless parametersa dimensionless sliding velocity and dimensionless oscillation amplitude. In the limit of very large oscillation amplitudes, known solutions previously reported in the literature are reproduced. The region of small amplitudes is described for the first time in this paper.

“…From the viewpoint of guidelines for mechanical structure design, to examine the stabilizing effect in more practical sliding systems, the above fundamental theory was extended to a two-degree-of-freedom (2DOF) sliding system [7]. First, the stabilizing effect of the YAM method in the 2DOF sliding system was confirmed by numerical simulations.…”

The stability of a two-degree-of-freedom (2DOF) sliding system with the velocity-weakening friction was examined by the eigenvalue analysis, where the in-plane anisotropy and the in-plane asymmetry were considered. The obtained eigenvalues were organized by using the minimum modal damping ratio as the stability maps. Selecting a stable point in the stability map corresponds automatically to embedding the Yaw-Angle-Misalignment (YAM) method in the mechanical structure design to avoid the instability. If we accept the mechanical structure design of sliding systems with the in-plane anisotropy and the in-plane asymmetry, we can find new stable conditions spread widely in the two-dimensional space, which are invisible from the conventional point of view.
