According to the structural dynamic modification theory, perturbed mode shapes can be expressed as a linear combination of unperturbed through transformation matrix T. This is proposed in this paper powerful technique determine whether discrepancies between two models attributed differences stiffness, mass, or both. It demonstrated that T becomes rotation when there are no mass discrepancies. In case discrepancies, and stiffness differences, decomposed into product containing information...
Model correlation techniques are methods used to compare two different models, usually a numerical model and an experimental model. According the structural dynamic modification theory, mode shapes estimated by modal analysis can be expressed as linear combination of through transformation matrix T. In this paper, T is proposed novel technique detect discrepancies between models in terms mass. The stiffness identified combining natural frequencies This methodology applied correlate results...
Modal mass is one of the modal parameters that are required to define dynamic behavior a structure when model used. In experimental analysis (EMA), masses least reliable parameter, while in operational (OMA), cannot be estimated because exciting forces not measured. this paper, concept cross-length between mode shapes formulated for continuous and discrete systems, important properties derived from definition. It demonstrated zero all modes constant density systems. For structures consisting...
Due to the brittle nature of glass, study response glass elements subjected dynamics loadings is great interest, mainly when human injury resulting from breakage may occur. Laminated consists two or more layers monolithic and one viscoelastic interlayers. In this paper, a technique predict dynamic (deflections stresses) laminated using linear elastic model proposed validated. first step, modal parameters are calculated superposition technique. Then, coordinates element estimated equations...
