Identification of constitutive properties of a laminated rotorat rest through a condensed modal functional
Published online by Cambridge University Press: 24 December 2010
Abstract
Predicting the dynamic behavior of laminated rotors in bending requires theidentification of the bending rigidity of the laminated core. An identification ofconstitutive properties is proposed on the rotor at rest, which is a first step forrotordynamics prediction. Modal parameters predicted and measured are included in afunctional based on a hybrid Rayleigh quotient and combined with the Guyan method, themaster degrees of freedom corresponding to the measurement points. The laminated corerigidity is extracted through a Levenberg-Marquardt minimization.
