Oscillations around 1/2 order subharmonic resonance are investigated in a rotor system with a radial clearance between the bearing and the casing by numerical simulations and experiments. The following phenomena due to impact in the bearing are found: (1) Combination oscillations of [p_fーp_b=ω] and [3p_fーp_b=2ω] occur in lower speed range of + (1/2)ω resonance. (2) Entertainment phenomena occur in the speed range of +(1/2)ω resonance. (3) Oscillations of ωーp_f occur around the speed range of +(1/2) ω resonance with self-excited oscillation of p_f. Furthermore entrainment phenomena and coupling between self-excited oscillation of p_f and oscillation of ω-p_f are explained theoretically by a similar self-excited and forced oscillation model of nonlinear van der Pol's equation. |
