The whirl instability of groove compensated journal air bearing is analyzed. The finite element method is used to obtain the numerical solution of the Reynolds equation and the computer simulation method is used to obtain the locus of the shaft center after a step displacement disturbance. From the shaft loci, the effects of various design parameters on the stability of the bearings are discussed.
