Abstract

Purpose

The purpose of this study is to investigate the hydrodynamic characteristics of journal bearings in a high-speed and heavy-load press system by considering thermal influence and cavitation.

Design/methodology/approach

A proper and effectual computational method is presented for steady-state analysis of fluid interaction in a rotor-bearing press system by combining computational fluid dynamics techniques.

Findings

The influences of eccentricity ratio, rotational speed and oil-film thickness on the hydrodynamic behavior of the journal bearing are studied.

Originality/value

The computational method can be used for creating a precise lubrication design for a journal bearing of a lubrication system.
