In order to perform updating on an FE model to be usedrnfor dynamic analysis, a set of data are needed for use as thernreference of the updating process. Usually, reference datarnsets comprise modal properties and/or FRFs which comernfrom modal tests conducted on actual structures. Althoughrnexperimental data can represent the dynamic properties ofrnthe structure with a certain degree of accuracy, there is arnwell-known limitation associated with information from suchrnexperiments in that the data available are incomplete. In thisrnpaper, an application of model updating using reference datarnobtained from a "supermodel" (instead of physical testrnstructure) is discussed.rnA new method is proposed in this paper to address thernquestion: "how can the information from a supermodel bernused in a model updating process?" The information fromrnboth the supermodel and the design model of the samernstructure is used to calculate the so-called the EquivalentrnElement Strain Energy (EESE) and Equivalent ElementrnKinetic Energy (EEKE) parameters. Comparing thesernparameters with those of the Element Strain Energy andrnElement Kinetic Energy from the supermodel, the methodrncan indicate areas in the design model where eitherrngeometrical or material properties need to be modified.rnSome case studies on theoretical models and an actualrnindustrial model are presented in this paper.
