Bearing characteristic of journal bearing applied biomimetics
Tribology International, 2020Abstract Journal bearings have been improved by reducing friction and increasing stability via various methods. However, if future applications require even better performance, a new approach will be required. In this study, we aimed to improve the bearing characteristics of journal bearings by incorporating biomimetics.

Experimental investigation into surface texture effect on journal bearings performance
Tribology International, 2019Hydrodynamic sliding bearings are designed to operate under fully flooded conditions to enable adequate film formation. In actual operating conditions, journal bearings could operate in a mixed or even boundary lubrication regime, for example, during the

An approach of simulating journal bearings-gear pump system including components' cavitation
Simulation modelling practice and theory, 2020The present study aims to solve a system-level problem about journal bearings-gear pump based on a novel simulation model. The model developed consists of different modules: a fluid dynamic model for pump, a lubrication model for bearings, a model for ...
