MODELING OF MACHINE-TRACTOR UNITS WORKFLOW ON THE USE OF BIOFUELS
It is considered in the work integrated mathematical model of the machine-tractor units (MTU) that takes into account the physic-chemical properties of biofuel. The novelty of this model is that it takes into account the impact of the working processes in the structural elements of the MTU, one by one influencing each other. This scientific approach to the calculation of the MTU provides the opportunity to evaluate objectively the impact of biofuel on the operational and technological indicators, taking into account the weather conditions, the physical and mechanical properties of the soil and other conditions that may diminish the impact of biofuel on the operation of the unit and distort the final results. In addition the model is adapted to use computer applications, which makes it possible to reduce significantly the complexity of the calculations and reduce the influence of the human factor.
