本文对垂直于滑动方向的面内振动对滑动摩擦的影响进行了理论分析。与前人对这种摩擦主动控制模式的研究不同，我们详细考虑了摩擦学接触刚度的影响，并表明在小的振动幅度下，接触刚度起着核心作用。在本文中，我们考虑了位移控制系统的情况，其中接触刚度与测量系统的刚度相比很小。结果表明，在这种情况下，宏观摩擦系数是无因次滑动速度和无因次振动幅度两个无量纲参数的函数。在极大振荡幅度的极限下，重现了以前文献中报道的已知解。本文首次对小幅度区进行了描述。
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.
