This paper deals with a self-excited vibration of a rotating Mindlin circular plate subjected to a concentrated frictional force exerted on its outer circumference. The authors discussed the internal resonance of the circular plate with imperfections. As typical of the imperfections, they considered the additional masses for the circular plate without imperfections. It turned out from the method of multiple scales the (1) the imperfections have a tendency to suppress the occurrence of the self-excited vibrations of not only single modes but also internal resonance, (2) the optimal arrangement of the masses to quench the internal resonance between two modes is the same as that for the lowersingle mode, and (3) the resulting vibration shows the waveforms with beat, and the waveforms of the higher mode are affected by the lower mode in the internal resonance.
