Vibration Response Characteristics of Bladed Disk with Continuous Ring Type Structure : Vibration Response Characteristics of Bladed Disk Losing Shroud and Stab(<Special Issue>Dynamics & Design Conference 2009)

Abstract

Recently, bladed disks with continuous ring type structure have been used in many kinds of turbo-machinery due to its high reliability. This paper, first, presents a simple analysis method for estimating vibration response characteristics of a bladed disk with continuous ring type structure losing a shroud and a stab. Second, the parametric study on the vibration response characteristics of a bladed disk losing a shroud and a stab is carried out utilizing the analysis method proposed here. From the calculated results, the vibration response characteristics of the bladed disk are clarified. Lastly, the results calculated by the simple analysis method proposed are compared with the results obtained from FEA in order to verify the analysis method.
