Abstract
This article presents an experimental study carried out on a rotor operating on two foil bearings. One of the bearings was built in a way to measure the temperature and deformation of the top foil of the foil bearing. The dynamic performance of the two bearing journals is presented herein using the vibration trajectories and journal positions in the foil bearing sleeve. Based on these results, a method for predicting the temperature distribution on the top foil was developed. Then, the correlations between the temperature distribution and the operating parameters of the bearing journal were illustrated. It has been observed that the symmetry of the temperature distribution on the top foil depends on the eccentricity of the rotor operation. The shape and size of the vibration trajectory had no significant effect on the temperature value in the bearing, unlike the position of the journal in the bearing. The process of loss of the gas lubricating film was observed, which provides insight into the phenomena that occur during the first few seconds of rotor operation. The areas in the bearing from which fresh air had been drawn into the gap between the journal and the top foil were also determined.
