Abstract
Scratches on bearing surfaces can significantly affect the performance and lifespan of journal bearings. This study investigates the impact of scratches on two-lobe journal bearings through both theoretical and numerical analyses. The theoretical approach provides insights into how scratches influence lubrication, while the numerical simulations investigate how the three key scratch parameters, namely width, position, and depth, affect bearing performance. Key metrics analyzed include pressure, velocity distributions, temperature profiles, eccentricity, attitude angle, minimum film thickness, and maximum temperature. The findings offer valuable guidance for optimizing bearing design, maintenance, and condition monitoring, contributing to enhanced reliability and operational efficiency.
期刊介绍：
Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International.
Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
