This research project aims at continue the cooperation between EPUSP and Universita Politecnica delle Marche. The focus herein is on studies associated with nonlinear dynamics for renewable energy systems. Besides technical discussions, the participants will plan the submission of proposals to research agencies. Finally, the participants will discuss aspects regarding the organization of …
Since the structures are becoming lighter and slender, their dynamic behavior have been considered of great relevance in modern engineering applications. In a classical engineering approach, structural responses are undesired and methods for suppressing them are pursued. The dynamic loads can be either monochromatic or polychromatic. In the case of polychromatic excitations, it is well kn…
Flow-induced vibrations (FIV) are commonly found in several technological applications and concern the existence of self-excited oscillations that may impact the structural lifespan. Hence, it is of interest the development of studies focusing on solutions that mitigate these vibrations. Among the suppression techniques, focus is placed on the passive one. Passive suppression does not nee…
In the offshore engineering scenario, oscillations of slender structures such as risers and TLP tethers are common problems. Particularly, two classes of problems are of interest: parametric instability phenomenon and vortex-induced vibrations (VIV).Parametric instability problems are caused by the temporal modulation of traction. Such a modulation is caused by the motions of floating uni…
Studies that aim at the vibration control of structural oscillations have marked importance in engineering design. Projects focused on passive suppression of vibrations are receiving efforts from the scientific community.In this context, the present research project focuses on the development of systems for nonlinear passive control of vibrations using nonlinear energy sinks (NESs) for sh…
This research project is associated with another project sponsored by FAPESP (grant 22/02995-9). Herein, focus is placed on the numerical-experimental study of a piezoelectric energy harvesting system. The problem at hand consists of a beam fitted with a piezoelectric patch. The governing equations of the solid-electric system will be derived by mean of Analytical Mechanics. Following, a …
The phenomenon of internal axial-flow-induced vibrations is one among many different types of fluid-structure interactions and is present in many engineering applications such as systems of pipes conveying fluid in heat exchangers, water supply networks and in the oil & gas industry. Since, in their myriad of applications, these systems are susceptible to flow-induced vibrations which can…
Systems in which one or more parameters of the governing equation of motion depend explicitly one time may be subjected to parametric excitation. Particularly, if the only time-dependent parameter is the stiffness, which varies following a harmonic and monochromatic function, the equation of motion assumes the form of the classical Mathieu's Equation. Depending on the parameters that char…
Vortex-induced vibration phenomenon (VIV) is very common in several engineering applications, particularly in offshore engineering. Slender structures, such as risers, are subject to this fluid-structure interaction phenomenon, which can accelerate the structural lifespan due to fatigue.VIV is a self-excited and self-limited phenomenon observed when the vortex-shedding is close to a natur…
Slender structures found in offshore engineering present a rich dynamic behavior from the scientific point-of-view and, consequently, demand a complex analysis. Both linear and nonlinear phenomena coexist and, hence, the complete analysis of this dynamics is not a trivial task. This research project will focus on two particular phenomena, namely, parametric excitation problems and Vortex-…

The phenomenon of internal axial-flow induced vibrations in pipes conveying fluid is one of several ways in which fluid-structure interactions manifest themselves. These vibrations may occur in many engineering applications such as production risers in offshore applications, ocean mining procedures, industrial heat exchangers and in in-flight refueling scenarios. Due to its wide array of …
The parametric excitation problem is governed by a non-autonomous and homogeneous equation. In this case, the parameters of the mathematical model explicitly depend on time. A particular case of parametric excitation problem is that in which the stiffness harmonically varies in time. In the latter case, the equation of motion is know as Mathieu's equation and, depending on the values of a…
Risers are slender cylindrical structures that convey oil and gas from the seabed to the floating unit and their dynamic behavior is the main technological motivation of this research plan.A particular phenomenon of interest in risers's dynamics is named vortex-induced vibration (VIV), a class of flow-induced vibrations problem characterized by oscillation amplitudes close to one structur…
