A Brief History of 30 Years of Model Updating in Structural Dynamics,appropriateness of a model has always preoccupied developers and practicing engineers. Because of the early focus on predicting the linear vibrations of coupled systems for aerospace and civil engineering applications, test-analysis reconciliation initially consisted in updating the FE matrices such

An Improved Expansion Process for Guyan Reduced Models: Technique for Improved Guyan Expansion Recoel reduction scheme available in all of the commercial finite element codes. As long as a sufficient number of active DOF are utilized, the Guyan reduction can produce reasonable results. However, there are errors due to the reduction and subsequent expansion of the reduced model back to the full sp

Identification of Independent Inputs and Their Spatial Positions,he outputs. It is shown that the number of independent inputs can be obtained from the effective rank of a matrix that can be formulated from the Fourier transform of the response signals and that the input location information is encoded in the image of the same matrix. A scheme to identify the tim

Parameter Identification for Nonlinear Dynamic Systems via Multilinear Least Square Estimation,is method the identified nonlinear model is expressed in a linear modal space with additional terms representing the nonlinear behaviour. These additional nonlinear terms are obtained by performing least square regression in a modal space. Implementing this methodology in a structure, a large number
