Application of passive control to energy harvester efficiency using a nonideal portal frame structural support system
(Sage Publications Ltd, 2014-03-01)
An analysis of a new energy harvester model is presented, based on a simple portal frame structure, considered a nonideal system due to the kind of excitation influenced by the response of the system, such as a direct ...
Three-dimensional formulation of a strain-based geometrically nonlinear piezoelectric beam for energy harvesting
(Sage Publications Ltd, 2021-01)
In this paper, the authors introduce a model of a strain-based geometrically nonlinear piezoelectric beam for modeling energy harvesters. A nonlinear shear-underfomable 3-D Rayleigh’s beam theory is used to model the ...
Demanda energética na colheita de híbridos de milho para silagem em função do estádio de maturidade e tamanho de partícula
(2014-02-26)
Corn is the crop most used for making silage. The efficiency of the process should also be evaluated by cost per kg of dry matter harvested (kgDM). The objective of this study was to evaluate energy consumption in the ...
Offshore Energy Harvesting of a Marine Floating Pendulum Platform Model
(Latin Amer J Solids Structures, 2019-01-01)
This work presents an analysis of an ocean wave energy harvesting system. This system is composed of a direct current (DC) power generator attached at the middle-top of a floating platform. A pendulum is connected to the ...
Using saturation phenomenon to improve energy harvesting in a portal frame platform with passive control by a pendulum
(2016-01-01)
A new model of energy harvester based on a simple portal frame structure subjected to saturation phenomenon is presented. Energy is collected via a piezoelectric device whose nonlinearities are considered in the mathematical ...
