摘要

本文提出了一种新的摩擦控制方法，该方法将内部刚度不均匀性引入到在粗糙表面上滑动的软材料表面。这种方法包括将硬颗粒嵌入软材料中以控制摩擦。当这些颗粒在滑动过程中遇到粗糙表面上的凹凸不平时，它们会触发局部的粘滑运动，导致能量耗散和宏观摩擦增加。通过一个具有三角形周期一维粗糙度的简化装置的实验证明了该概念的有效性。该方法可用于各种软质材料滑动面的设计。

Friction control in soft materials enabled through local stick-slip motion at contact interface

This paper presents a novel friction control method that introduces internal stiffness inhomogeneity into soft material surfaces that slide on rough surfaces. This approach involves embedding hard particles within a soft material to control friction. When these particles encounter asperities on a rough surface during sliding, they trigger a local stick-slip-like motion that leads to energy dissipation and increased macroscopic friction. The validity of the concept was demonstrated through experiments using a simplified setup with triangular periodic one-dimensional roughness. This method is expected to be useful for designing various soft material sliding surfaces.
