In this paper, the forced response of mistuned bladed disc is studied when excitation frequencies are high and high families of modes are excited. A model reduction technique is developed for the computationally efficient analysis of high-frequency forced response for bladed discs using high-fidelity finite element models. The finite element model of a sector of a tuned bladed disc is used to provide primary information about modal properties, which are used in the analysis of mistuning structures. The blade mistuning is modelled by specially defined mistuning matrices used for simulating experimentally measured scatter of blade natural frequencies. The effects of mistuning on high-mode forced response of bladed disc are discussed.
