Abstract:
In 2006, de Klerk, Rixen, and de Jong introduced the Lagrange multiplier frequency based substructuring method (LM FBS) as an alternative to the classical frequency based substructuring method (FBS). LM FBS has several advantages over FBS, as it easier to implement and more efficiently handles problems with more than two substructures. LM FBS has also been shown to be quite adaptable and has recently been extended to include flexible connection elements at the interfaces between substructures. One other advantage of the LM FBS that has not been fully exploited to date is the fact that the dimension of the mobility matrix of the coupled system remains the same as the block-diagonal uncoupled system. This feature allows the LM FBS to be more easily interpreted in terms of structural modification and offers the analyst the option to use the normal modes of the uncoupled system as a basis for tracking and quantifying the influence of substructure coupling on the dynamic response of the coupled system. This talk will demonstrate such a structural modification framework utilizing LM FBS.
