Title: Automatic Process For The Determination Of Modal Supersets Of Residual Flexibilities Used In The Modal Synthesis Method
Author: Kurka P.R.G.

Abstract: The work presents an automatic process for the selection of modes of substructures with the purpose of buiding the superset of a residual flexibility model. This superset in used in the modal synthesis method for the experimental analysis of large structures. The qualitative indication of modes to be eliminated in a substructure plays an important role in the precision of the synthesis process. Actual mode elimination techniques are based on arbitrary user decisions which could lead to the extinction of modes which would have an important contribution to the synthesis of the complete structure. The technique is applied here for systems without damping. Such a technique relies on a relative weighting of the modes of the substructures, based on Euclidian norm calculations.
