Nonlinear Study of Rotor-AMB System Subject to Multi-Parametric Excitations

摘要：

　　The non-linear response of a rotor supported by active magnetic bearings (AMB) under multi-parametric excitations is investigated.The method of multiple scales is applied to analyze the response of two modes of a rotor–AMB system near the primary resonance case.The steady-state response of the system is studied numerically,applying the frequency response function method.It is shown that the system exhibits many typical non-linear behaviors including multiple-valued solutions,jump phenomenon,hardening non-linearity.The effects of the different parameters on the steady state solutions are investigated and discussed.
