Experimental Study of the Influence of Rotor Dynamics on the Temperature Distribution of a Gas Foil Bearing

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