The Hopf bifurcation behaviour of a symmetric rotor/seal system was investigated using Muszynska's non-linear seal #uid dynamic force model. For a perfectly balanced system, the instability from certain critical equilibrium positions is proved to be the result of Hopf bifurcation and only the superc
