| 摘 要： | 根据Ｍ－Ｂ分形接触模型对静摩擦系数进行预测。对分形参数Ｄ、Ｇ及材料参数φ对静摩擦系数的影响进行研究。结果表明静摩擦系数随载荷的增加而增加。这与在极低载荷下静摩擦系数很小的试验事实吻合，因此，Ｍ－Ｂ分形接触模型可能仅适用于载荷极小的情况。

| Abstract: | M-B fractal contact model is used to predict the static friction coefficients in this paper. Effects of the surface fractal parameter D, C,and the material parameter on the static friction coefficient are discussedThe predicted static friction coefficient increases with the increases of normal load. This coincides with the experimental results that static friction coefficient is very low under very small normal load condition, thus, the M-B fractal contact model could be used under small normal load condition., |
