Application of Krylov subspace reduction methods in frequency based substructuring

摘要

The scope of this paper is the application of Krylov subspace reduction methods in frequency based substructuring. For that purpose the structure will be subdivided into substructures; these substructures will be condensed by a Krylov subspace reduction method and afterwards assembled to represent the dynamic behavior the structure. The method applied will be explained and the performance of the technique will be demonstrated using a benchmark example.
