Abstract
A simulation environment for rotordynamical problems has been developed at our institute. The environment is based on a framework for the efficient simulation of multibody systems with unilateral contacts and elastic elements. The simulation comprises the modelling of a 3D flexible rotor, unilateral contacts with and without friction between the rotor and stationary parts and an interface to Matlab/Simulink to co-simulate the feedback control of active elements. The fundamentals of unilateral constraints allow a detailed simulation of processes like contact /detachment, stick/slip or impacts with and without friction. The simulation environment has been tested and verified using experimental results from a rotor test rig with an active auxiliary bearing. In this project the possibilities of controlling a rubbing rotor with an active auxiliary bearing have been investigated in experiments and theory.
