Identification of constitutive properties of a laminated rotor at rest through a condensed modal functional

Abstract

Predicting the dynamic behavior of laminated rotors in bending requires the identification of the bending rigidity of the laminated core. An identification of constitutive properties is proposed on the rotor at rest, which is a first step for rotordynamics prediction. Modal parameters predicted and measured are included in a functional based on a hybrid Rayleigh quotient and combined with the Guyan method, the master degrees of freedom corresponding to the measurement points. The laminated core rigidity is extracted through a Levenberg-Marquardt minimization.
