Desenvolvimento de uma planilha eletrônica para a determinação da potência disponível na barra de tração de tratores agrícolas.

Abstract

This work deals with a development of an electronic sheet, implemented from algorithm developed in Visual Basic, to determine the drawbar available power. The procedure used allows the determination of the traction force, speed, drawbar available power, fuel consumption, specific fuel consumption and the traction coefficient of tractor obtained from a trial. Besides, calculates the drawbar available power considering the “Factor 0,86” rule proposed by Wendel Bowers, yield traction equation and the ASAE D497 – 4 rules. The electronic sheet developed can be considered a fast and efficiency tool for analysis related to the drawbar effective power of a tractor.
