目的
粘弹性材料的各向异性表面起到滑动摩擦的作用；本文的目的是研究各向异性表面对接触面积和摩擦系数的影响。
设计/方法论/途径
基于考虑部分接触和粗糙度斜率变化的可拓佩尔森理论，使用复弹性模量和各向异性功率谱来计算摩擦系数。
研究结果
得到不同角度和偏心率下相对接触面积随速度变化的比率，并且需要考虑弹性模量的影响。平行于运动方向的摩擦系数随着角度的增大或偏心率的减小而减小。当角度或偏心率增大时，垂直方向的摩擦系数发生不规则变化。
原创性/价值
Persson 工作的扩展考虑了部分接触和粗糙度的有效均方斜率，应用于研究滑动摩擦，并考虑了弹性模量对接触面积的影响。
Purpose
The anisotropic surfaces of viscoelastic materials play a role in sliding friction; the purpose of this paper is to study the effect of the anisotropic surfaces on contact area and the friction coefficient.
Design/methodology/approach
A complex elastic modulus and an anisotropic power spectrum are used to compute the coefficient of friction based on the extension Persson theory which considers the partial contact and the variation in the roughness slopes.
Findings
The ratios of the relative contact area that varies with velocity are obtained with different angles and eccentricities, and the effect of the elastic modulus needs to be considered. The coefficients of the friction parallel to the direction of motion decrease as the angle increases, or as the eccentricity decreases. The friction coefficients in the vertical direction change irregularly when the angles or eccentricities increase.
Originality/value
An extension of Persson’s work considering the partial contact and the effective mean square slope of the roughness is applied to study sliding friction, and the effect of the elastic modulus on contact area is considered.
