Evaluation of wear resistance by the friction coefficient of a modified radial bearing with account of non-linear factors
https://doi.org/10.46973/0201-727X_2025_3_180
Abstract
A computational model of a modified radial bearing design is proposed. This model considers nonlinear factors describing the movement of a micropolar lubricant within the bearing clearance with a non-standard bearing profile adapted to friction conditions. Unlike previous approaches, the developed model makes it possible to more accurately calculate the distribution of pressure and velocity in a layer of micropolar lubricant when determining the load capacity and the value of friction coefficient. The novelty of the study lies in the simultaneous consideration of nonlinear factors and rheological properties of the micropolar lubricant of a modified radial bearing with a support profile adapted to friction conditions, as well as in the comprehensive verification of the model using experimental data, ensuring its practical significance.
