Modelagem de máquina pneumática recolhedora de frutos de café em terreiro usando análise por elementos finitos

Abstract: Teve-se o objetivo de desenvolver um modelo matemático por meio de análise de elementos finitos, utilizando o programa computacional ANSYS®, versão 5.7, para otimizar o projeto de máquina recolhedora de frutos de café no terreiro. A modelagem da máquina foi realizada com base no levantamento das características aerodinâmicas dos frutos de café e da vazão de ar necessária para o transporte pneumático dos frutos. Foram obtidas, experimentalmente, as pressões estáticas nos dutos da máquina, sendo esses valores co… Show more

“…Labor shortages in rural areas, increases in crop-growing areas, and the need for reductions in processing times have led to an increased demand for mechanization in coffee production (MAGALHÃES et al, 2006). In a country such as Brazil, which is a leading coffee producer, research institutions and the national coffee industry must find solutions to these problems.…”

“…The use of computer software has proven to be an important tool in the development of success and reliability of successful and reliable products, offering countless possibilities for assessing the technical and economic viability of products without physical models needing to be built (MAGALHÃES et al, 2006). The use of computeraided design (CAD) makes it possible to reduce costs and increase safety by facilitating the prediction of possible operational and material failures.…”

Important results were obtained in agricultural engineering using structural simulations, such as in Magalhães et al (2006), Celik et al (2011), Nilnont et al (2012, Li et al (2013), Oliveira et al (2014), Silva et al (2014) and Hernandez et al (2016), and also in studies on vibration conducted by Pinho et al (2014) and Almeida et al (2015).…”
