Abstract The article proposes a mathematical model of vertical oscillations of a wheeled tractor, making it possible to take into account power losses of the drive of the main movement of the tractor due to its vertical oscillations. The model includes a number of empirical factors that make its application more efficient. It is shown that the value of losses associated with vertical oscillations of the tractor is affected by a significant number of factors, including mass, frequency of natural oscillations and speed of tractor movement, as well as energy consumption for deformation of tires and overcoming their resistance to rolling. The most important of these are the frequency of oscillations and the speed of the tractor movement. The use of the developed model makes it possible to assess the influence of the mentioned factors on the additional load of the drive during vertical oscillations of the tractor and to establish the relationships linking them, as well as to assess the influence of these factors on the increase of load of the drive in case of vertical oscillations of the tractor and to develop technically reasonable measures to reduce them. The results of the studies can be used in the analysis of the influence of the features with the drive “ICE — generator — electric motor — transmission” on their operability when used in tractor technology.
