Modeling of Tractor Fuel Consumption

In this paper, the energy diagnostic of tractor performance consists in evaluating (fuel consumption per hectare—dm3 ha?1) for a given agricultural operation and combining it with working capacity, also called productivity (area productivity—ha h?1). One methods solving problem is identification functioning process machine unit. A model unit was developed, considering rear linkage system implement force control adjustment system. order to analyze system, mathematical function built: tractor-implement-soil, defining physical connections interdependencies between individual subsystems Based on model, simulation developed implemented Matlab/Simulink environment. The Simulink package used test set. efficiency indicators according adopted criteria were calculated evaluation block. To evaluate process, technical operational parameters tractor, type tool, soil properties taken into account. results studies obtained validated are consistent experimental data from appropriate conditions.
