ARTICLE ANNOTATION

quote
This article investigates the relationship between the working width, operational productivity, and specific fuel consumption of a combined machine aggregated with the ARION 630C tractor based on mathematical modeling methods. As a result of the study, the dependence of fuel consumption and operational productivity on the working width was expressed using second-order regression equations. The coefficients of determination for the obtained models were R² = 0.98 and R² = 0.96, respectively, indicating their high accuracy. The significance of the regression coefficients and the adequacy of the model were confirmed using Student’s t-test and the Fisher criterion. The calculations showed that the optimal working width of the aggregate is 4.1 m, at which the fuel consumption is minimized and the operational productivity is close to its maximum value. The research results provide an opportunity to substantiate the design parameters of combined aggregates and develop practical recommendations for their efficient utilization.
