Zusammenfassung:The sensitivity method is applied for bearings stiffness parameter estimation of an experimental rotor system. For model updating, critical shaft speeds are used. The reliability of the sensitivity method is tested on a simple example. The results show that this method can be successfully applied to adjust the finite element model to the experimental data.
