The effect of global viscoelasticity on rubber friction with Schallamach waves

Abstract A mathematical model developed previously for predicting adhesive sliding friction of rubber on a hard surface in the presence of Schallamach waves is extended here to include global effects of viscoelasticity, besides the previously included viscoelastic effects in the neighborhood of the debond (shear crack) tips; the crack tip model is unchanged. We find that global viscoelasticity limits the maximum sliding speed and minimum wavelength for which a wave train can exist and, as expected, increases the friction force. The model is shown to improve upon the agreement with experimental data on wave speed and wavelength in the previous paper.

全局粘弹性对橡胶摩擦的 Schallamach 波的影响

摘要 先前开发的用于预测存在 Schallamach 波时橡胶在硬表面上的粘附滑动摩擦的数学模型在此扩展到包括粘弹性的全局效应,除了先前包括的脱粘(剪切裂纹)尖端附近的粘弹性效应; 裂纹尖端模型不变。我们发现全局粘弹性限制了波列可以存在的最大滑动速度和最小波长,并且如预期的那样增加了摩擦力。该模型在与前一篇论文中关于波速和波长的实验数据的一致性基础上有所改进。
