Resumo: | The tire inflation pressure, among other factors, determines the efficiency in which a tractor can exert traction. It was studied the effect of using two tire inflation pressures, 110.4 kPa in the front and rear wheels, 124.2 kPa in the front wheel and 138 kPa in the rear wheels, the energetic efficiency of an agricultural tractor of 147 kW of engine power, in the displacement speed of 6.0 km.h-1, on track with firm surface, with the tractor engine speed of 2000 rpm. For each condition of the tire pressure, the tested tractor was subjected to constant forces in the drawbar of 45 kN and 50 kN, covering 30 meters. It was used a randomized complete block with a 2x2 factorial arrangement (tire pressure and drawbar power) with four replications, totaling 16 experimental units. Data were subjected to analysis of variance, using the Tukey test at 5% probability for comparison averages. The lowest hourly and specific fuel consumption, the lowest slippage of the wheelsets and the highest efficiency in the drawbar was obtained with the tire inflation pressure of 110.4 kPa in the front and rear tires of the tractor, highlighting that lower pressures improve energetic and operational performance of the tractor. |

Estudou-se o efeito da utilização de duas pressões de inflação dos pneus 110,4 kPa nos rodados dianteiros e traseiros, 124,2 kPa nos rodados dianteiros e 138 k Pa nos rodados traseiros , na eficiência energética de um trator agrícola de 147 kW de potência no motor, na velocidade de deslocamento do trator de 6,0 km.h-1, em pista com superfície firme, com rotação do motor do trator em 2.000 rpm. Para cada condição de pressão dos pneus, o trator ensaiado foi submetido a forças constantes na barra de tração de 45 kN e 50 kN, percorrendo 30 metros. Utilizou-se o delineamento experimental em blocos ao acaso, com um arranjo fatorial de 2x2 (pressão dos pneus e força na barra de tração), com quatro repetições, totalizando 16 unidades experimentais. Os dados foram submetidos à análise de variância, aplicando o teste de Tukey a 5% de probabilidade, para a comparação das médias. O menor consumo horário e específico de combustível, a menor patinhagem dos rodados e o maior rendimento na barra de tração foram obtidos com a pressão de inflação dos pneus de 110,4 kPa nos pneus dianteiros e traseiros do trator, evidenciando que pressões mais baixas melhoram o desempenho energético e operacional do trator.Universidade Federal do Ceará Depto. de Engenharia AgrícolaUniversidade Federal do Ceará Centro de Ciências Agrárias Depto. de Engenharia AgrícolaUNESP Faculdade de Ciências AgronômicasUniversidade Federal do Ceará Departamento de Engenharia MecânicaInstituto Federal CatarinenseUNESP Faculdade de Ciências AgronômicasAssociação Brasileira de Engenharia Agrícola (SBEA)Universidade Federal do Ceará (UFC)Universidade Estadual Paulista (Unesp)Instituto Federal CatarinenseMonteiro, Leonardo De A.Albiero, DanielLanças, Kleber Pereira [UNESP]Bueno, André V.Masiero, Fabricio C.2014-09-30T18:18:21Z2014-09-30T18:18:21Z2013-08-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article758-763application/pdfhttp://dx.doi.org/10.1590/S0100-69162013000400015Engenharia Agrícola.
