Determining Optimal Boundary Conditions for Modal Analysis of Axial Turbomachine Rotors

The analysis of modal characteristics in axial compressor/turbine rotors is hindered by inconsistent practices regarding constraints and boundary conditions. Specifically, there is debate over how to properly constrain the rotor for modal analysis, particularly for integrally bladed blisks. The lack of standardization leads to varying results and uncertainty in selecting the most appropriate method.
