Research of the process of a technological module aggregation with a mobile energy vehicle of the “Autotractor” type

Abstract

Purpose. Create a mathematical model that will make it possible to establish relationships between the main design parameters of a mobile energetic means of the type “Avtotractor” (MEM) and technological modules (TM) during the execution of the aggregation process. Methods. Used analytical methods and mathematical modeling of the process of operation of agricultural units, tractor and car theory. Numerical modeling was carried out using a personal computer. Results. A system of differential equations has been created, which allows simulating and analyzing the movement processes and modes of operation of the unit. In particular, by varying the weight of the vehicle, parameters of the running system (pressure in the tires of the wheels, dynamic rolling radius of the wheels, the number of driving axles), the resistance of the agricultural machine or equipment, the gear ratio of the transmission etc. Conclusions. A mathematical model of the movement process of the agricultural unit based on the MEM-115 “Avtotractor” was obtained, which makes it possible to describe the relationship between the main design parameters of the MEM and its operating modes. Keywords: equivalent dynamic model, system of differential equations, motion process, slip coefficient, weight utilization coefficient.
