THE DESIGN AND DEVELOPMENT OF A HIGH SPEED JOURNAL BEARING TEST RIG FOR MEASURING DYNAMIC CHARACTERISTICSOF OIL FILM BEARINGS

摘要

This paper outlines the design and development of a test rig used to determine the dynamicrncharacteristics of oil film journal bearings. Some background is given on the main design,rnoperating parameters, and instrumentation systems. Recent developments include the ability torntest at higher speeds using a specially designed drive motor and new test and analysis techniques.rnNewly commissioned software and detailed design improvements have also been incorporated tornenable the rig to be used on a continuing basis for a range of bearing types and sizes. Somerntypical output plots are given for a 5 pad pivoted shoe bearing. A tribute is given to the late KeithrnBrockwell, a respected colleague and fellow researcher in the field.
