This paper deals with the self-excited vibrations of a rotating Mindlin circular plate subjected to a concentrated frictional force as a function of relative slip velocity exerted on its outer circumference. It turns out from the averaging method and a direct numerical integral method that only single modes are stable, the generating modes are fixed in space even if the circular plate rotates and the resulting modes deviate from those generated in a stationary circular plate in the rotating direction due to rotation. Furthermore, the self-excited vibration becomes unstable or the steady-state solutions cease to exist, as the rotating speed is increased. The analytical results are confirmed by the experiment.
