Abstract

The formulation and method for solving the contact problem of the rigid cylinder sliding over the wavy surface of the viscoelastic layer bonded to the rigid base is presented under the assumption that the cylinder axis is perpendicular to the surface waviness cross-section. The calculation results allow assessing the effects of sliding velocity, surface layer microgeometry, and its relaxation properties on the contact characteristics (the position and size of the actual contact region and the contact pressure distribution) and on the friction force’s deformation component. Depending on the sliding velocity, the contact region may be solid or consisting of discrete contact spots with high values of the maximum contact pressure for the same surface waviness. It is also established that the friction force increases with increasing waviness amplitude and viscosity of the surface layer.

波浪形粘弹性基底上圆柱体滑动接触时的摩擦特性计算

摘要

在假定圆柱体轴线垂直于表面波纹横截面的假设下，提出了解决刚性圆柱体在粘结到刚性基底的粘弹性层的波浪形表面上滑动的接触问题的配方和方法。计算结果允许评估滑动速度，表面层微观几何形状及其松弛特性对接触特性（实际接触区域的位置和大小以及接触压力分布）以及摩擦力变形分量的影响。取决于滑动速度，接触区域可以是实心的或由具有相同表面波纹度的最大接触压力的高值的离散接触点组成。
