Dynamic Condensation for Eigensolutions and Eigensensitivities
The substructuring methods reduce the global model into a modal space spanned by a few substructural master modes, based on which the dynamic analysis, sensitivity analysis, and model updating are implemented accurately and efficiently. In this chapter, model condensation method is introduced to compute the eigensolutions and eigensensitivities of large-scale structures. The model condensation method reduces the global model in the physical coordinates determined by a few master DOFs. If the DOFs associated with the selected elemental parameter are chosen as the additional master DOFs, the eigensensitivity of the reduced model is obtained by directly performing iterations on the stiffness and mass matrices of the master DOFs.
