This paper deals with subharmonic and ultra-subharmonic oscillations in a rotating shaft system with nonlinear spring characteristics involving quartic terms. When the shaft is supported by double-row angular contact ball bearings, nonlinear terms of the fourth order appear in the restoring force in addition to the second and the third terms. Owing to this quartic nonlinear component, subharmonic oscillations of the order 1/4 and ultra-subharmonic oscillations of the orders 3/2 and 2/3 will probably appear. We analyzed these oscillations theoretically paying attention to the nonlinear components represented by the polar coordinates and investigated the probability of occurrence and the shapes of the resonance curves. We also conducted experiments and compared their results with the theoretical ones.
