... constraint equation. It is required because the Eqs. ( 21 ) are underdetermined. To understand the cause of this indeterminacy, consider a rotor in which each sector is mistuned the same amount. Due to the symmetry of the mistuning, the rotor’s mode shapes will still look tuned, but its frequencies...

... of a mistuned bladed disk from distortion of a structural mode. In this approach, the mistuned mode is represented as a sum of the tuned modes, where the coefficients of the tuned modes in the modal summation represent the amount of distortion present in the mode. It was shown that for small damping...
