Resumo: In order to determine the durability of agricultural machines, it must firstly understand stresses level of the components in analysis. The level of stresses can be obtained by experimental tests which demand high costs for prototypes and instrumentation, or analytically which demands timing and most of cases, calculations become unfeasible due to geometry complexity. An alternative which helps agriculture engineering for the stresses calculation is the Finite Element Method, but the use of this method for straw cutting seeder is still incipient. This work proposes finite element analysis of a four bars mechanism, similar to a real one, used in straw cutting seeder, for stresses evaluation. Von Mises stresses were extracted and analyzed from commercial software. Results demonstrated consistent when compared to analytical data, taking in consideration that statistical methods for comparing the results were not adopted. Values lower than 275 N mm-2 (yield strength of the material adopted in the simulations) were found, which showed the potentiality on the Finite Element Method application for straw cutting seeder projects.

O nível de tensões pode ser obtido experimentalmente, o que demanda custo elevado de protótipos e instrumentação, ou por meios analíticos, o que demanda tempo e na maioria dos casos, os cálculos tornam-se inviáveis pela complexidade geométrica. Uma alternativa que tem auxiliado engenheiros agrícolas no cálculo de tensões é o Método dos Elementos Finitos, porém o seu uso ainda é incipiente em mecanismos de corta-palhas de semeadora-adubadoras. Este trabalho propõe o uso do Método dos Elementos Finitos para avaliar o nível de tensões nas barras acionadoras e seguidoras de uma semeadora-adubadora, análogo a um mecanismo real, usado no corte de palhada de uma semeadora. Tensões de von Mises foram extraídas e analisadas em um programa comercial e os resultados mostraram coerência quando comparados com valores analíticos, levando-se em consideração que não foi adotado método estatístico para comparação dos resultados. Valores inferiores a 275 N mm-2 (tensão de escoamento do material adotado nas simulações) foram encontrados, o que demonstra a potencialidade na aplicação do Método dos Elementos Finitos em projetos de mecanismos de corta-palhas de semeadora-adubadoras.Universidade Federal de Viçosa - UFV2016-10-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/58610.13083/reveng.v24i4.649Engineering in Agriculture; Vol. 24 No. 4 (2016); 368-374Revista Engenharia na Agricultura - REVENG; v. 24 n. 4 (2016); 368-3742175-68131414-398410.13083/reveng.v24i4reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/586/396Volpato, CarlosMagalhães, RicardoBarbosa, JacksonCarvalho, Wanielleinfo:eu-repo/semantics/openAccess2023-01-19T13:31:24Zoai:ojs.periodicos.ufv.br:article/586Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:31:24Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
