Updating of Finite Element Models Including Damping [PDF]
Transactions of the Korean Society for Noise and Vibration Engineering, 2012 Finite element models are updated in two stages in this paper. In the first stage, damping is neglected, and mass and stiffness matrices of a finite element model are updated using an optimization technique. The objective function for optimization consists of natural frequencies and mode shapes obtained from experimental modal testing data and finite ...
