This paper deals with summed-and-differential harmonic and super-summed-and-differential harmonic oscillations in a rotating shaft system which are caused by quartic nonlinearity. We theoretically analyze these oscillations, paying special attention to the nonlinear components represented by the polar coordinates. We clarify which kind of nonlinear component has an influence on each oscillation. In experiments, the shaft was supported by double-row angular contact ball bearings, and the restoring force had nonlinear spring characteristics involving quartic nonlinearity, in addition to quadratic and cubic ones. Experimental results were compared with the theoretical results regarding the probability of occurrence and the shape of the resonance curve. As the result, it has become clear that such analysis is very effective in predicting the occurrence of oscillations in a practical rotating shaft system.
