Abstract
Coupled free vibration characteristics of practical bladed disks are computed using triangular shell element and cyclic symmetry. Potters' method is used for solution of the eigenvalue problem. Blade-disk joint constraints are applied based on Love-Kirchhoff hypothesis. Blade to blade variation of looseness at the blade-disk joint is also considered. Results of three practical bladed disks with different blade aspect ratios and having approximately the same disk radii ratio are presented. For large aspect ratio of blades, the bladed disk vibration behavior is simple. For the medium and small aspect ratio blades, complex mode behavior is observed.
