摘要

A frequency domain transformation is the basis for a general approach to the identification of finite element modeling errors. The transformation provides information as to the location of modeling errors and provides the error matrices of stiffness, mass, and damping. The transformation is shown to have the unique property of directly revealing that the process of instrumenting an actual structure with a finite number of response transducers defines a reduced order system, with an attendant set of singular frequencies responsible for the nonlinear distortion imposed on the corrective parameters of stiffness, mass, and damping. Actual test data demonstrating this phenomenon will be presented.
