A Continuous Model for the Dynamical Analysis of Mistuned Bladed Rotors
Figure 4
Eigenmodes of the imperfect rotor, evaluated according to the HOM model, the L-HOM model, and the EB model. The imperfection is introduced by increasing the mass of the fourth blade of the perfect rotor described in Section 4.1 by , with respect to its nominal value. – – green: perfect rotor, — red: imperfect rotor using HOM model, blue: imperfect rotor using L-HOM model, – · – black: imperfect rotor using the EB model.
