A New Model Correcting Method for Quadratic Eigenvalue Problems Using a Symmetric Eigenstructure Assignment
Finite element model correction of quadratic eigenvalue problems (QEPs) using a symmetric eigenstructure assignment technique is proposed by Zimmerman and Widengren 1989, which incorporates the measured model data into the finite element model to produce an adjusted finite element model on the damping and stiffness matrices that matches the experimental model data, and minimizes the distance be...
متن کاملNew Model Correcting Method for Quadratic Eigenvalue Problems Using Symmetric Eigenstructure Assignment
Finite element model correction of quadratic eigenvalue problems (QEPs) using a symmetric eigenstructure assignment technique was proposed by Zimmerman and Widengren (Zimmerman, D., and Widengren, M., “Correcting Finite Element Models Using a Symmetric Eigenstructure Assignment Technique,” AIAA Journal, Vol. 28, No. 9, 1990, pp. 1670–1676) and incorporates the measured model data into the finit...
متن کاملA New Model Updating Method for Quadratic Eigenvalue Problems. II
In this paper, we continue our paper [7] to develop an efficient numerical algorithm for the finite element model updating of quadratic eigenvalue problems (QEPs). This model updating of QEPs is proposed to incorporate the measured model data into the finite element model to produce an adjusted finite element model on the mass, damping and stiffness that closely match the experimental modal dat...

Finite element model updating of quadratic eigenvalue problems (QEPs) is proposed by Friswell, Inman and Pilkey 1998, to incorporate the measured model data into the finite element model to produce an adjusted finite element model on the damping and stiffness that closely match the experimental modal data. In this paper, we mainly develop an efficient numerical method for the finite element mod...
متن کاملSolving Large-scale Quadratic Eigenvalue Problems with Hamiltonian Eigenstructure Using a Structure-preserving Krylov Subspace Method
We consider the numerical solution of quadratic eigenproblems with spectra that exhibit Hamiltonian symmetry. We propose to solve such problems by applying a Krylov-Schur-type method based on the symplectic Lanczos process to a structured linearization of the quadratic matrix polynomial. In order to compute interior eigenvalues, we discuss several shift-and-invert operators with Hamiltonian str...
