Abstract

Traditionally, the friction force has been the benchmark for quantifying energy dissipation in frictional phenomena. In this study, we introduce an atomic chain friction model that illuminates the conversion of kinetic energy into potential energy through interfacial forces. The energy dissipation process is characterized by the release of partial potential energy in the form of phonons, quantifiable by a frictional damping coefficient. We have determined that this damping coefficient is significantly influenced by the intrinsic dynamic properties of the friction system. To expand on this foundation, we formulate an advanced phononic friction model that accurately predicts the friction forces measured using an atomic force microscope (AFM). Our model reveals that energy dissipation is caused by vibrations occurring both parallel and perpendicular to the sliding motion. These findings profoundly enhance our understanding of the basic mechanics of friction and open new avenues for innovative strategies for the active management and reduction of energy dissipation in diverse mechanical systems.

对滑动摩擦的声子分析

传统上，摩擦力一直是量化摩擦现象能量耗散的基准。在这项研究中，我们引入了一个原子链摩擦模型，该模型说明了动能通过界面力转化为势能。能量耗散过程的特征是声子形式的部分势能释放，可以用摩擦阻尼系数来量化。我们已经确定该阻尼系数受摩擦系统的内在动力特性的显著影响。在此基础上，我们建立了一个先进的声子摩擦模型，该模型可以准确地预测原子力显微镜（AFM）测量的摩擦力。我们的模型表明，能量耗散是由平行和垂直于滑动运动的振动引起的。这些发现深刻地增强了我们对摩擦基本机制的理解，并为主动管理和减少不同机械系统能量耗散的创新策略开辟了新的途径。
