Abstract：The inevitable mistuning in aeroengine bladed disks can lead to considerable increase in vibratory amplitude
and stress, and thus deteriorate the structural integrity and reliability. Therefore, the dynamic characteristics of mistuned
bladed disks have been drawn great attention in both academic and engineering fields around the world. This paper
presents a review of the modeling and analysis methods for mistuned bladed disks, with particular emphasis on the geometric
mistuning of integrally bladed rotors and multistage bladed disks. The recent researches on mathematical representation
and reduced-order modeling of geometric mistuning are introduced. Important developments and future research directions
in this area are highlighted.
