The main goal of this study is to investigate the dynamic interactions between a flexible portal frame and a nonlinear electrical support excitation. The numerical analysis shows a complex behavior of the system, which can be observed by phase spaces, Poincare sections and bifurcation diagrams.1093-1101engElectro-dynamical shakerflexible portal framenonlinear dynamicsArtigo10.3233/SAV-130824WOS:000327249900006Acesso abertoWOS000327249900006.pdf
