High frequency vibration was observed in operation of a soot-blower. To clarify its mechanism analysis and experiment was done on a system consisting of a flexible shaft rotating slowly, on which friction acts tangentially at an intermediate position. Analytical results show that the real part of an eigenvalue does not always decrease monotonically with the order of mode. Therefore, some higher modes may appear more prominently. Large vibration is observed in experiment where real part of an eigenvalue is large.
