Special Issue Information

Dear Colleagues,

This Special Issue of Lubricants, titled "Surface Machining and Tribology", aims to explore the latest advancements and research at the intersection of surface machining and tribology. Surface machining processes, such as grinding, milling, turning, and polishing, play a crucial role in defining the surface characteristics of materials, directly impacting their tribological performance, including friction, wear, and lubrication. Understanding the intricate relationship between surface machining parameters and tribological properties is essential for optimizing material performance in various industrial applications, from automotive to aerospace and biomedical engineering.

This Issue welcomes contributions from researchers and professionals working on experimental, theoretical, and computational approaches to surface machining and tribology. Topics of interest include, but are not limited to, advanced surface finishing techniques, surface texture analysis, tribological behavior of machined surfaces, wear mechanisms, novel lubricants and coatings, and the impact of machining-induced microstructural changes on tribological performance. By bringing together insights from these interconnected fields, this Special Issue aims to provide a comprehensive understanding of how machining processes can be tailored to enhance surface functionality and durability, driving innovation in the design of high-performance materials and components.

The rotation speed directly influences the vibration and lubrication behaviors of gear pairs, but studying the effects of time-varying rotation speeds during their operation poses substantial challenges. The present work proposed an approach to analyzing the dynamic response and lubrication performance of spur gear pairs under time-varying rotation speeds. A single-degree-of-freedom torsional dynamics model was established to capture the vibration responses and meshing forces of a gear pair, with the meshing stiffness modulated by the time-varying rotation speed. Additionally, a transient elastohydrodynamic lubrication model of the gear system was proposed to obtain the pressure pro-file and film shape, incorporating the effects of time-varying rotation speeds. Three types of time-varying rotation speeds were investigated: acceleration, deceleration, and oscillation. The results reveal that the time-varying rotation speed induces chaotic motion of the gear system, resulting in significant changes in the dynamic meshing force, entrainment velocity, and curvature radius of the gear pair compared to those in constant-speed scenarios. The lubrication performance under time-varying rotation speeds also shows diverse dynamic characteristics, highlighting significant differences from that observed under a constant rotation speed. These insights contribute to a more comprehensive understanding of gear dynamics under realistic operating conditions, enhancing gears’ performance and reliability in practical applications.
