A procedure for determining the sensitivities of the eigenvalues and eigenvectors of damped vibratory systems with distinct eigenvalues is presented. The eigenpair derivatives of the structural and mechanical damped systems can be obtained consistently by solving algebraic equations with a symmetric
An ecient algorithm with proven numerical stability is derived for computation of eigenvalue and eigenvector derivatives of damped vibratory systems with multiple eigenvalues. In the proposed method, adjacent eigenvectors and orthonormal conditions are used to compose an algebraic equation whose ord
The classical inverse sensitivity approach was applied. In the presented application, the deviations between analytical and measured natural frequencies and mode shapes were minimised to update user selected stiffness, mass and geometric parameters. The selection of the updating parameters was based
