Abstract
The purpose. To heighten smoothness of course of specialized wide-track agricultural vehicles by justification of scheme, mechanically-technological and other parameters, and also performances of long- edged profile of unevenness of agricultural background in traces of shaped technological track. Methods. Original positions of theoretical mechanics, statistical dynamics of the theory of autocontrol of linear dynamic systems and theory of tractor, creation of programs and calculations for PC are used. Results. New mathematical models are elaborated of operation of the created specialized wide-track agricultural vehicle for track system of farming agriculture in vertical plane. Their use allows justifying demands to performances of long-edged profile of unevenness of agricultural background in traces of technological track, raising smoothness of a course in view of kinematic and power correlations of its power and technological part. Conclusions. Smoothness of course of specialized wide-track agricultural vehicle as dynamic system, which moves on traces of the fixed technological track, essentially depends on structure of its long-edged profile, rigidness of tires of anvil wheels (which value can be influenced in the fixed limits by changing air pressure). Dynamics of vertical vacillating of technological part is caused by its operation mass.


Key words: track system of farming agriculture, widetrack agricultural vehicle, differential equations, solutions on PC.
