摘　　要：基于稳态滑动摩擦系统模型,采用球-盘摩擦副定量分析研究法向载荷、滑动速度、初始表面纹理和摩擦副材料对稳态摩擦因数的影响,得到稳态摩擦因数在不同工况下的变化规律。结果表明:滑动摩擦的稳态摩擦因数与磨损率正相关,周向纹理表面的稳态摩擦因数最大,无纹理表面的稳态摩擦因数次之,径向纹理表面的稳态摩擦因数最小;无论何种初始表面形貌,随着转速的增加,稳态摩擦因数先减小后增大,随着法向载荷的增大,稳态摩擦因数呈增长趋势;较深较宽的表面纹理具有更大的稳态摩擦因数和更大的瞬时波动;稳态摩擦因数也与摩擦副材料的选取有关。Based on steady-state sliding frictional model,the influences of normal loading,sliding speed,initial surface texture and material on steady-state frictional coefficient were researched quantitatively with ball-disk friction pair. Rules of steady-state frictional coefficients under different operating condition were obtained. The results show that steady-state frictional coefficients of sliding friction are positively correlated with wear rates. Steady-state frictional coefficients of different surfaces in morphology descending order are circumferential texture,untextured and radial textures. Regardless of the initial surface,frictional coefficient decreases first and then increases with the increase of revolving speed. With the increase of normal loading,it presents an upward trend. Deeper or wider textured surfaces have higher frictional coefficients and larger instantaneous fluctuation. Moreover,frictional coefficients also associate with the selection of friction pair materials.
