Frequency Domain Structural Identification.

Abstract

The Structural Synthesis Transformation is used to conduct structural system identification in the frequency domain. For spatially complete where each of the frequency response functions at every degree of freedom of each of the coordinates of the modeled system are available it shown that the theory exactly identifies all modeling errors. For spatially incomplete cases where the frequency response functions are available only at a proper subset of the degrees of freedom of the finite element model, single mode solutions are computed over intervals about modes of the experimental system using matrices and complex valued line integrals. Methods of forming multiple mode solutions from the single mode solutions are explored.
