| description | In this work, a numerical model simulating <i>friction hysteresis</i> for lubricated rough and textured surfaces in contact is presented. <i>Friction hysteresis</i> occurs in sliding contacts that are subjected to a non-constant (e.g., sinusoidal) motion. It refers to the phenomenon where the observed friction force during acceleration differs from that during deceleration. Besides the dynamics of the sliding system, a classic mixed friction model is adopted, in which the transient Reynolds equation for the description of the thin lubricant film is combined with a statistical Greenwood–Williamson model for the description of rough surface asperity contacts. The model enables the prediction of the <i>friction hysteresis</i> for predefined contact descriptions (i.e., surface profile and roughness, lubricant, etc.) and allows the study of the physics and parametric influences of dynamically sliding contacts. In this paper, it is shown that (i) <i>friction hysteresis</i> is captured by classic transient models for mixed lubrication; (ii) system parameters, such as roughness, applied load, viscosity and velocity, including the offset, amplitude and motion reversal, influence the shape and area of <i>friction hysteresis</i>; and (iii) the selection of the aforementioned parameters may minimize <i>friction hysteresis</i>. |
