The results indicated that the centrifugal force reduces the localization; when the Young's modulus of all blades are in the tolerance of 5%, the blade-disc can regarded as an cyclic symmetry system. The study results given in the present paper have provided a variety of effective numerical methods for the study of vibration characteristics of blade, disc and the blade-disc system. These research results can also serve as a helpful guide to the vibration study of other rotating components.
