Modal-based diagnostics of cracked rotors

Sawicki, Jerzy T. / Gyekenyesi, Andrew L. / Baaklini, George Y.

Different approaches are used to sense and to localize a damage of rotating structures. Most of the methods take advantage of the dynamic behavior of the structural model [1-7]. This paper uses the modal and sensor norms, as defined in [8], to determine damage locations. The proposed approach allows localization of damaged elements within a structure, and provides information concerning the impact of the damage on the structure's natural modes of vibration.
