论文摘要

我们概述了一个现象学模型,以评估相互接触中两个物体之间界面的摩擦。尽管该方法是一般的,但激发该方法的应用程序是离散元素方法。摩擦过程的运动学是根据相互接触中两个表面上接触点的相对3D运动表示的。该模型产生三种摩擦载荷的表达式:滑动力,滚动扭矩和自旋扭矩。该方法的基石是在相互接触中跟踪两个物体表面上接触点的演化/路径的过程。该模型的显着属性在于其在3D设置中同时计算幻灯片,滚动和旋转摩擦载荷的能力,可为任意几何体平滑体,同时考虑静态和运动学摩擦系数。

We outline a phenomenological model to assess friction at the interface between two bodies in mutual contact. Although the approach is general, the application inspiring the approach is the Discrete Element Method. The kinematics of the friction process is expressed in terms of the relative 3D motion of the contact point on the two surfaces in mutual contact. The model produces expressions for three friction loads: slide force, roll torque, and spin torque. The cornerstone of the methodology is the process of tracking the evolution/path of the contact point on the surface of the two bodies in mutual contact. The salient attribute of the model lies with its ability to simultaneously compute, in a 3D setup, the slide, roll, and spin friction loads for smooth bodies of arbitrary geometry while accounting for both static and kinematic friction coefficients.
