Abstract:

The resonant response of integrally bladed rotors at various modes and harmonic excitations is investigated in this work. Two AMM finite element models FEM were created of a 20-bladed IBR. Strain gages in as-manufactured models AMM using this method changes the IBRs predicted mistuning. AMMs generated via optical topography measurements and mesh morphing should be acquired using clean, non-strain gaged rotors or the material properties of strain gaged elements need to be altered to more accurately model the component.
