Increasing the efficiency of using the SUTB technology in the operation of agricultural units

Abstract

The article proposes a method for determining the energy parameters of a machine-tractor unit to increase the efficiency of using the SUTB (shifted-up and throttled-back) technology for stepped transmissions of agricultural tractors. The theoretical substantiation of the new method and the results of practical testing in real field conditions are presented.

Power balance of all-wheel drive mobile power vehicle

“…To assess all the components of the energy balance, it is necessary to determine the torques and rotational speed of the power take-off shaft and the axle shafts of the driving wheels, the speed of the machine, the pulling force on the hook, engine speed, fuel consumption and other indicators [10]. The authors were given the following tasks:  Obtaining initial data for the development of a mathematical model for calculating the performance of an all-wheel drive mobile power vehicle of the traction and energy concept of class 0.6 based on the components of the power balance;  Study of the potential possibility of using the experimental sample as a sprayer and as a tractor of traction class 0.…”
