Abstract

To accurately predict the dynamics of most structures, a representation of damping must be used. This paper focuses on structural damping and the identification of structural damping for complex systems with cyclic symmetry such as bladed disks and integrated (one-piece) bladed disks (blisks) with mistuning. The damping identification methodology is demonstrated together with two measurement filters for a complex structure, namely an integrated bladed disk with stiffness mistuning.
