Nonlinear forced oscillations of a rotating circular disk excited at a fixed point in space are considered. For theoretical analysis, modal equations are derived from the governing partial equations. Then, based on these modal equations, the characteristics of oscillations induced by a harmonic excitation are discussed for typical cases. The case considered is one in which the excitation frequency is near the midpoint of the primary resonance points of the forward- and backward-traveling modes. Numerical calculation is conducted. It is shown that oscillation which is composed of the forward- and backward-traveling modes occurs, and that two peaks appear in their response curves. Experimental analysis is conducted, which confirms the validity of the theoretical analysis.
