Mixed and thermal elastohydrodynamic simulation of a low-loss gear considering the gear system

Friction
The reduction of load-dependent gear power loss is one of the key aspects in gear design. Therefore, a detailed power loss prediction and the local investigation of its drivers are essential. In this study, the model of Farrenkopf et al.

Thermal Elastohydrodynamic Lubrication Analysis of Grease in Tripod Sliding Universal Couplings

Lubricants
The tripod sliding universal coupling (TSUC) is a novel type of coupling developed through independent research. This study theoretically investigates the effects of the grease flow index and initial viscosity on thermal elastohydrodynamic lubrication ...

Coupling Study on Quasi-Static and Mixed Thermal Elastohydrodynamic Lubrication Behavior of Precision High-Speed Machine Spindle Bearing with Spinning

Machines
In this work, a modified numerical algorithm that couples the quasi-static theory with the mixed thermal elastohydrodynamic lubrication (mixed-TEHL) model is proposed to examine the mechanical properties and lubrication performance of the spindle bearing

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 ...
