Abstract
The effect of mistuning on the vibration of bladed disks has been extensively studied in the past 30 years. Most of these analyses typically cover the case of small variations of the elastic characteristics (mass and stiffness) of the blades. In this work we study the not so common case of the forced response of a stable rotor with damping mistuning. We use the Asymptotic Mistuning Model (AMM) to analyze this problem. The AMM provides a simplified model that describes the effect of blade to blade damping variation, and gives information on the underlying mechanisms involved in its action.
