title = "Mode localization in a satellite system due to parameters detuning",
abstract = "When modeling structures consisting of numerous repeated segments, structural dynamicists typically assume that the geometry and material properties of repeated elements are identical. The mode shapes obtained from this idealized model are global in nature, and the modal response extends throughout the structure. However, the presence of small irregularities in nominally periodic structures may localize the modes of free vibration and inhibit the propagation of vibration. The finite element method is used to study localization of a satellite with solar panels which the symmetry condition would be violated. Then, a measure for the degree of mode localization is defined and used in the numerical analysis. The results show that small deviations of the solar panel lengths lead to the occurrence of strongly localized modes. The values of localization factors increase with the ratio of imperfections.",
