Projeto, dimensionamento e simulação de um conjunto trator-implemento de propulsão híbrida.

Abstract

The article presents an analytical method for the development of an agricultural tractor with regard to the use case of planting, where it draws a row crop planter with traction from a hybrid produlsion system, where the specific goal is the sizing of the internal combustion and electric machines. With basis on operating and soil property parameters, it is possible to predict the torque and power requirements from the tractor at all of the high demand points and, hence, establish the peak power values for the system. The presented methodology is tested considering a soybean planting operation, in which a power-split planetary gearing topology of the hybrid powertrain is considered, and the results shows a possible configuration that has the best overall efficiency of the system.
