Model-updating for self-adjoint quadratic eigenvalue problems
This paper concerns quadratic matrix functions of the form L(λ) = Mλ2 +Dλ+K where M,D,K are Hermitian n× n matrices with M > 0. It is shown how new systems of the same type can be generated with some eigenvalues and/or eigenvectors updated and this is accomplished without “spill-over” (i.e. other spectral data remain undisturbed). Furthermore, symmetry is preserved. The methods also apply for H...
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...
متن کاملA New Model Updating Method for Quadratic Eigenvalue Problems
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 کاملDiagonalizable Quadratic Eigenvalue Problems
A system is defined to be an n× n matrix function L(λ) = λ2M + λD +K where M, D, K ∈ Cn×n and M is nonsingular. First, a careful review is made of the possibility of direct decoupling to a diagonal (real or complex) system by applying congruence or strict equivalence transformations to L(λ). However, the main contribution is a complete description of the much wider class of systems which can be...
