Keywords:
Active magnetic bearing, computer model of dynamics of a flexible rotor on active magnetic bearings, dynamics influenced by structural deviations, flexible rotorAbstract
An algorithm for accounting for identification of the structural deviations impacting the dynamics of a flexible multispan rotor on full electromagnetic suspension in an actively developed computer model of dynamics of a flexible rotor on active magnetic bearings is presented. The algorithm is illustrated by applying it against the scale model of a rotor on active magnetic bearings.
