Desempenho Do Trator De 157kw Na Condição Manual E Automático De Gerenciamento De Marchas

Abstract: Resumo: O sistema de gerenciamento automático de marchas permite ao trator, na rotação de trabalho estabelecida no motor, extrair o máximo de desempenho de tração do trator. Neste trabalho, os benefícios de gerenciamento automático de marchas foram comprovados através da comparação da velocidade, patinagem, consumo horário de combustível, rendimento e potência na barra de tração, força e consumo específico durante deslocamento do trator nas condições manual e automática de gerenciamento de marcha. O experiment… Show more

“…The tractors had the engine speed adjusted to 1970 RPM during the experiment, with the FWD activated and full fuel tank. The instrumentation described below was connected to the data acquisition system made on a printed circuit board, with a 1-Hz acquisition frequency (Jasper et al, 2016).…”

“…The modernization of agriculture in recent years allowed using mechanized assemblies in many agricultural operations. Therefore, validations under laboratory and field conditions are necessary to reproduce the worst operating conditions of these machines, ensuring maximum operational performance (Jasper et al, 2016, Beckmann & Santana, 2019. Gomes et al (2016) assessed operational performance by applying 15.4 and 20.5 kN of force to the drawbar and obtained the best fuel efficiency when the tractor dragged a load of 20.5 kN, confirming the importance of the correct dimensioning of the assembly.…”

“…A principal utilização do trator agrícola é a movimentação e transmissão de energia a implementos para a realização de trabalhos no campo. Em tratores acima de 130 Kw, essa utilização se dá em 90% dos casos pela barra de tração (JASPER et al, 2016).…”
