Um estudo da influência do comportamento não linear na análise modal experimental
(Universidade Estadual Paulista (Unesp), 2019-07-30)
Os métodos de análise modal tradicionalmente são limitados aos sistemas vibrando em regime linear de movimento. Assim, quando as estruturas sofrem altas amplitudes de excitação ou são muito flexíveis, gerando possíveis ...
Nonlinear oscillations analysis of power systems including facts devices based on the modal series method
(Universidad Michoacana de San Nicolás de Hidalgo, 2012-06)
This thesis describes the procedure followed to represent the nonlinear modal interaction of a power system dynamic based on the modal series method. The method is based on the multidimensional Laplace transform and theorems ...
Caracterização experimental de sistemas mecânicos com comportamento não-linear
(Universidade Estadual Paulista (Unesp), 2015-08-20)
A large number of structural engineering designs are seeking for more economic concepts, which leads to lightweight and flexible structures. These structures have nonlinear beha- vior caused by large deformations. In that ...
