A cyclic symmetry approach to the structural dynamic analysis of bladed discs

This paper presents the development of a cyclic symmetric approach to the complete stress, free vibration, transient and stationary response analysis of rotating tuned bladed disc systems taking into account all the complications involved. Starting from Biezeno's approach to the analysis of individual blades and discs, the continuing development of different methodologies and their limitations as applied to practical systems are discussed. The advantages, versatility and usefulness of the present approach are demonstrated by means of the results obtained for a number of cases both by theoretical and experimental means.
