As part of my thesis, I have carried out modal analysis of a compressor rotor blade with and without fouling mass accumulation and plotted this on a Campbell diagram as shown.
Only considering the design rpm case, I have tried to simulate the blade vibration amplitudes using harmonic response on ansys workbench using the force exerted by the gas on the blade. But I want to implement the excitation frequencies (multiples of running frequency from campbell diag.) into the model and see the effect on blade vibration amplitudes. Is this possible?
