Data-driven modelling of TEHL line contacts: ANN-based prediction of friction, film thickness, and temperature

Tribology International
Conventional Thermo-Elastohydrodynamic Lubrication (TEHL) simulations, while accurate, are computationally expensive and impractical for system-level analyses. In this study, Artificial Neural Network (ANN)-based surrogate models were developed for predicting key TEHL outputs, including Coefficient of Friction (CoF), rolling friction, maximum ...
