当两个接触的固体在没有润滑的情况下缓慢地相互滑动时，可能会观察到间歇性振动现象。这种速率相关的摩擦行为被称为粘滑运动，这种运动可以损害机器和结构的稳定性。本研究的目的是提出一种数值方法来分析粘滑运动；该方法基于使用速率相关摩擦模型实现的有限元方法。首先，我们通过将速率相关摩擦模型的结果与不同材料和动态条件下的实验结果进行比较，证明了该模型的能力。然后，对速率相关的摩擦滑动行为（包括粘滑运动）进行了简单的有限元分析，以检验材料、几何特性和边界条件对数值结果的影响。这种数值方法不仅考虑了摩擦和材料的特性，而且考虑了边界条件的变化。
When two solid bodies in contact slide slowly past each other without lubrication, an intermittent vibration phenomenon might be observed. Such rate-dependent frictional behaviors are referred to as stick–slip motions, and such motions can impair the stability of machines and structures. The aim of this study is to propose a numerical approach for analyzing stick–slip motion; the approach is based on the finite element method implemented using a rate-dependent friction model. First, we demonstrate the capability of the rate-dependent friction model by comparing its results with experimental results obtained under various material and dynamic conditions. Then, a simple finite element analysis of rate-dependent frictional sliding behavior, including stick–slip motion, is carried out to examine the effect of the material and geometric properties and boundary conditions on the numerical results. The present numerical approach can consider not only the properties of friction and materials but also variations in boundary conditions.
