AI-Based Mathematical Modeling and Simulation of Thermal Effects in Lubrication of Rolling/Sliding Contacts
Year: 2025
Type: article
Abstract: In this study, we investigated the thermal effects of non-Newtonian fluids in the lubrication of rollers under rolling or sliding contacts, considering both uniform and non-uniform conditions using advanced AI-based mathematical tools. Our findings indicate that temperature influences stability by slightly shifting the position of the pressure peak away from the center line of the contact. Despite this shift, the pressure peak consistently appears near the exit of the film, regardless of thermal effects. Additionally, the squeezing motion of the surfaces significantly impacts the pressure peak, with both cavitation pressure and temperature increasing as the squeezing velocity decreases.
