The results determine the acceleration and the mass of the tractor MTZ-80

The performance of machine-tractor units depends on many factors and production conditions, and primarily on the energy intensity of the process. The main indicator of the energy intensity of the process is the traction resistance of the aggregated agricultural machine. The absence of a simple and reliable method for determining this indicator leads to the heterogeneity of the devices used, often manufactured on their own, and this entails different reliability of the results. Therefore, the development of methods and means of determining the traction resistance of agricultural machines, acceptable not only for testing stations, but also for specific farms, is very relevant and of considerable interest. In this paper, we propose an operational method for determining the traction resistance of mounted agricultural machines, based on the analysis of parameters of transient acceleration modes of machine-tractor units with an instantaneous increase in fuel flow. The aim of the work is to develop and complete the measuring and computing complex, as well as to conduct experimental studies to determine the values of acceleration of the tractor and its reduced weight on one of the increased gears, allowing to implement this method of determining the resistance of agricultural machines. For the realization of left targets was developed and assembled measuring and computing complex determine the dynamic characteristics of machine-tractor units, through which with the aid of patented techniques on the base station «Kislyakovskaya» Kushchevskaya district of Krasnodar region was carried out experimental studies to determine the acceleration values of the tractor MTZ-80 and its given mass in one of the elevated gear. The obtained results allow to implement the proposed method for determining the traction resistance of agricultural machinery.
