When a rotor system is supported by single-row deep groove ball bearings, nonlinear spring characteristics appear due to clearance of bearings. In such rotor systems, the vibration characteristics change due to the effect of nonlinearities. In this paper, we studied vibration control of nonlinear rotor systems with a dynamic absorber. We clarified that the nonlinearity influences on the vibration characteristics of controlled rotor systems. If the rotor system has a isotropic symmetrical nonlinearity, we cannot use fixed points theorem for the optimization of the dynamic absorber, because the vibration increases due to the effect of this nonlinearity. We also clarify that the vibration control of the nonlinear rotor systems with a dynamic absorber can be achieved by considering such effects of nonlinearity in designing the parameters of dynamic absorber.
