Forced response of mistuned bladed discs in gas flow: a comparative study of predictions and full-scale experimental results
For the first time, an integrated experimental-numerical study of forced response for a mistuned bladed disk, using full chain high-fidelity modelling of gas flow and nonlinear vibrations was performed for mistuning predictive analysis of a bladed disc with and without friction dampers. The simulation results were validated on a full-scale test rig with the excitation by aerodynamic force from gas flow.
