Hydrodynamic lubrication is an effective method for connecting various relatively moving structural components in engines, rotors, manipulators, and other systems.Surface texturing can enhance the performance of such contacts.Initially, a theoretical framework for modeling textured surfaces of journal bearings is introduced, which is then employed to analyze the dynamic behavior of rotors.Additionally, a pinon-disc approach for determining the properties of a lubricated textured surface is presented.The objective of utilizing the pin-on-disc method is to enhance computational models of lubricated textured pins by comparing experimental measurements with numerical simulation results.The knowledge gained can be applied to optimize parameters in computational models of hydrodynamic contact for textured surfaces in various applications, such as the model presented for journal bearings.
