Theoretical Analysis and Experimental Research of Surface Texture Hydrodynamic Lubrication

This paper established a mathematical model of hydrodynamic lubrication through theoretical analysis, solved the key variables of the mathematical model through simulation and validated the mathematical model using the experimental results. The purpose is to summarize a set of surface texture theory and optimal selection equations for complex working conditions. After comparing the experimental results with the results obtained by the mathematical model, it is found that the two are basically the same in the ranking of the anti-friction properties of different textures, and there is an error of 10%-40% in the friction coefficient value.
