Clarification of the characteristics of a modified radial bearing design taking into account nonlinear factors
Incoming article date: 30.05.2025The paper presents a calculation model for assessing the wear resistance of radial plain bearings with a polymer coating and a groove, taking into account inertial effects and nonlinear properties of the medium under steady-state friction. Clarified analytical dependencies have been developed to improve the accuracy of calculations of the hydrodynamic characteristics of the bearing. The main objective of the study is to create a multifactorial model that takes into account the influence of the bearing geometric parameters (the presence and configuration of the groove), the properties of the polymer coating and the inertial force. The model allows predicting the bearing life in real operating conditions, taking into account the influence of various factors, which increases the accuracy of design and optimization of the design. The results of the work are aimed at improving the operational reliability of plain bearings due to more accurate prediction of their wear resistance and optimization of design parameters.
