Thermohydrodynamic study of misaligned plain journal bearings - comparison between experimental data and theoretical results

Hydrodynamic journal bearings are essential components of high speed machinery. Under severe operating conditions, manufacturing defects or thermal distortions may induce running problems such as misalignment. The aim of this paper is to present a realistic numerical model in order to predict the misaligned plain journal bearing performance under steady-state conditions. Therefore, a three-dimensional thermohydrodynamic (THD) analysis has been developed and the predictions obtained with the proposed numerical model are validated by comparison with measurements carried out on our test device.
