Circumferential Film Thickness Measurement Data from a Bespoke Journal Bearing Test Platform

This data provides the raw and processed film thickness measurement results from a bespoke journal bearing test platform. Lubricant film thickness has been determined in the present work via a range of ultrasonic techniques, observing changes in signal amplitude, phase and resonant frequency. Test cases include steady state shaft-aligned, shaft-misaligned and shut-down operating conditions. Film thickness results are compared against the Raimondi-Boyd theoretical prediction model and gap sensor measurements.
