Modelling analysis and identification of misalignment in rotor systems integrated with active magnetic bearings

Abstract

In this work model based identification of misalignment in coupled rotors with integrated active magnetic bearings is studied The stiffness of the coupling is modelled as the sum of static stiffness and time varying additive stiffness The additive coupling stiffness model is developed based on weight dominance criteria and a suitable steering function The steering function is used to mimic the multiharmonic nature misalignment forces as noticed in various experiments The first model of t...
