Fuel consumption of a sugarcane harvester in different operational settings
(Univ Federal Campina Grande, 2016-06-01)
The interventions performed during the mechanized harvesting are essential to improve the operational performance of sugarcane harvesters and reduce operational costs. The objective of the present study was to evaluate the ...
Design and optimization of electromagnetic transducer for aeroelastic energy harvesting
(2019-08-01)
The energy harvesting from oscillations of structures immersed in a moving fluid has received attention from the scientific community in recent years. Particularly, oscillations resulting from dynamically stable non-linear ...
SHIFTS AND HARVESTING SYSTEMS ON QUALITY OF IMPURITIES SAMPLES IN SUGARCANE
(Soc Brasil Engenharia Agricola, 2017-05-01)
Semi-mechanical and mechanical harvesting methods may influence the content of impurities in harvested sugarcane. This study aimed to evaluate the quality of three mechanical methods of sugarcane harvesting: one semi-mechanical, ...
On energy harvesting from ambient vibrations through an oscillating pendulum system fixed to a suspended plataform
(2020-01-01)
In this paper, we present numerical investigations of a pendulum system to harvest energy from the ambient. The mathematical model of the pendulum is obtained considering a harmonic displacement of its base. For power ...
Monitoring of soybean mechanical harvesting as a function of plot shapes
(2017-01-01)
Information on harvester performance is important in the management and optimization of mechanized agricultural systems. In this sense, the aim of this study was to monitor the operation quality of soybean mechanical ...
Harvesting Systems, Soil Cultivation, and Nitrogen Rate Associated with Sugarcane Yield
(2018-09-01)
The adoption of mechanical harvesting of green cane gives rise to concerns as to whether systems developed under burnt cane harvesting are applicable to a green cane harvesting system. In particular, tillage, which is an ...
Implementation of an energy harvesting system by piezoelectric elements exploiting the human footsteps
(Institute of Electrical and Electronics Engineers Inc., 2017)
The fundamental idea of this research work is to present an approach to energy harvesting, which basically uses piezoelectric technology and is implemented in a shoe. It takes advantage of the energy that the user waste ...
