Abstract The authors propose a new philosophy and theory for rubber friction and wear that are significantly different from the existing classical theories. Several distinctive features of rubber friction such as the exceedingly high friction coefficient and the intense stick-slip motion during frictional sliding all result from the sticky surface behavior exhibited by a cross-linked rubber, where there is a meniscus force brought about at the interface between the rubber and the rigid surface. The total friction coefficient μall incorporates three factors including an adhesion term μadh, a deformation term μdef and a crack formation term μcrac. This generates an equation μ all = μ adh + μ def + μ crac ≒ K 1 ηv [ 1 + K 2 ( tanδ 2 ) + 2 K e c ) E - 7 / 6 W 1 / 6 ] where η is the viscosity of the uncross-linked phase, E the modulus of the cross-linked rubber, v sliding velocity, c crack length, W normal load, K1, K2, Keare all coefficients whose characteristics also govern rubber wear. The adhesion term is the most dominant factor during rubber friction, which roughly contributes about 70–80% of the total friction coefficient according to a very rough estimation. The close relationships between the observed stick-slip motion, abrasion pattern formation and wear have been verified experimentally. The abrasion pattern is initiated by the high frequency vibration and the steady abrasion pattern together with steady wear is promoted by the stick-slip motion. Steady wear rate V ˙ could be estimated theoretically as a function of the steady abrasion pattern distance Dab using an equation V ˙ = k’Dab3, which indicates that many of the characteristics observed in rubber wear are also fundamentally governed by the intense stick-slip motion induced by the sticky rubber surface.

一种新的橡胶摩擦磨损广义哲学和理论

摘要 作者提出了一种与现有经典理论显着不同的橡胶摩擦磨损理论和新理论。橡胶摩擦的几个显着特征，如摩擦滑动过程中极高的摩擦系数和强烈的粘滑运动，都是由交联橡胶表现出的粘性表面行为引起的，在交联橡胶之间的界面处产生弯月面力。橡胶和刚性表面。总摩擦系数 μall 包含三个因素，包括粘附项 μadh、变形项 μdef 和裂纹形成项 μcrac。这产生了一个方程 μ all = μ adh + μ def + μ crac ≒ K 1 ηv [ 1 + K 2 ( tanδ 2 ) + 2 K ec ) E - 7 / 6 W 1 / 6 ] 其中η是粘度未交联相，E 交联橡胶的模量、v 滑动速度、c 裂纹长度、W 法向载荷、K1、K2、Keare 所有系数，其特性也控制橡胶磨损。粘合项是橡胶摩擦过程中最主要的因素，根据非常粗略的估计，它大约占总摩擦系数的 70-80%。观察到的粘滑运动、磨损模式形成和磨损之间的密切关系已通过实验得到验证。磨损模式由高频振动引发，稳定磨损模式与稳定磨损一起由粘滑运动促进。稳定磨损率 V ˙ 可以从理论上估计为稳定磨损模式距离 Dab 的函数，使用方程 V ˙ = k'Dab3，
