The non-linear response of a rotor supported by active magnetic bearings is investigated, and both primary and internal resonances are considered. The method of multiple scales is used to obtain four "rst order ordinary di!erential equations that describe the modulation of the amplitudes and phases

A procedure for estimation of non-linear stiffness parameters of rolling element bearings supporting a flexible rotor, based on analysis of the random response signals picked up from the bearing caps, is developed. The non-linear multi-degree-of-freedom equations, governing the motion of a flexible
This study attempts to explore the possibility of estimation of linear and non-linear stiffness parameters of rolling element bearings in rotor systems experiencing harmonic excitation from unknown imbalance as well as random excitation from a variety of sources, primarily the progressive random det
