Sistemas concentrados e distribuídos através da análise modal adjunta
Este estudo visou a utilização direta da análise modal adjunta em sistemas não-clásicos de natureza concentrada e distribuída, explorando o conceitos de biortogonalidade modal e da resposta impulso evolutiva e estacionária. Discutiu-se a natureza do espectro para diversas classes de sistemas, em …

Análise modal assintótica da estabilidade de estruturas reticuladas espaciais
This work presents a solution, by the Finite Element Method, for non-linear asymptotic analysis of elastic stability for space frames under conservative loads. The general non-linear equilibrium and critical equilibrium equations are obtained through a Lagrangian formulation, by analysing the …

Análise modal operacional de uma bomba centrífuga submersa utilizando a decomposição melhorada no domínio da frequência
The identification of modal parameters of electrical submersible pumps (ESP) is part of the process of increasing the reliability of this equipment, which is installed in places that are inaccessible, from a maintenance point of view, for oil exploitation, such as offshore oil wells and seabed, so …

Avaliação da estabilidade a pequenos sinais em sistemas CA/CC em paralelo
… link controls. The studies are performed using modal analysis techniques for power systems, as well as linear and nonlinear time domain simulations. The small signal theory is used to identify the critical modes of oscillation from the HVDC, in detriment of the stability margin. The simulations …
