Abstract: Purpose This study aims to use a machine learning (ML) model for the prediction of traction coefficient and asperity load ratio for different surface topographies of non-conformal rough contacts. Design/methodology/approach The input data set for the ML model is generated using a mixed-lubrication model. Surface topography parameters (skewness, kurtosis and pattern ratio), rolling speed and hardness are used as input features in the multi-layer perceptron (MLP) model. The hyperparameter tuning and fivefold c… Show more

“…It is believed that understanding the surface topography effect on the CoF by developing a simple and accurate numerical model will helps designing advanced machining processes for producing desired surface topography to achieve significant reduction in the CoF. Also, the present numerical model can be used to generate huge data sets for training of artificial neural network models considering different surface topography as an input, and to predict the optimum surface topography (Prajapati et al, 2023). In the present work, the extensive rheological properties of SQL facilitate the use of advance rheological relations and accurate value of Eyring stress for specified load and temperature (Xu et al, 2023).…”
