Mathematical modeling of the interaction of the main parts of a wheel tractor and the numerical determination of the operator’s seat oscillation

Abstract

In article is given mathematically modeling of fluctuation, movement and kinematic forward axle, suspension bracket of a skeleton, engine, cabin and seat of the wheel tractor. It is given an analytical type of the equation, the describing vertical fluctuations and longitudinally angular fluctuations of a cabin and the main parts of the tractor. Using this model will be found as far as distances are displaced the main parts of the tractor at vibration. The equations of linear system fluctuation with one degree of freedom of the under cabin damper, which shock-absorber of the tractor, are described.

Technical and technological ways to reduce soil compaction to preserve its fertility

“…For standard tires, the indicators reach 1.2-2.0 kgf / sm 2 -for light tractors, up to 2.5-3.5 kgf / sm2 -for heavy ones, up to 3-5 kgf / sm 2 -for combines and trailers in a static condition at full load [11][12][13]. Soil compaction depending on the number of tractor passes in the field, 0-0.30 cm, g/sm 3 The density was measured in layers of 0...10 sm, 10...20 sm, and 20...30 sm [14][15][16]. Suppose the T-150K tractor makes 5…6 passes.…”

The importance, methods of land leveling and analysis of equipment for their implementation

“…Cotton and other crops are well developed on the levelled lands. When machine-tractor units work on uneven fields, the traction resistance of the tool changes, resulting in reduced speed, increased vertical vibrations, which negatively affects the operation of the machine-tractor unit and increase the moisture content of the soil surface [20][21][22][23][24][25][26]. Therefore, high-quality levelling of the ploughed soil is required before the implementation of technological processes and surface irrigation in the cultivation of crops [1,2].…”

Digital Agriculture: “Internet of Things”

“…Today's generation is witnessing the beginning of revolutionary changes in agriculture [16][17][18][19][20][21][22][23][24]. We are talking about a new generation of Agro technology -the so-called precision farming.…”

“…The main directions of development of agriculture in the future will be organic and eco logical products [23,24,28,29]. The Internet of Things technologies will add to their effectiveness, with the help of which it is possible to obtain information about soil moisture, the optimal ratio of feed for livestock, harvesting and yield.…”
