Construction of accessory to СЗ-3,6А drill seeder intended for its technological capabilities enlargement is described. The modernized seeder provides seed sowing into soils cultivated by different ways, namely conventional, minimum tillage and no-tillage ones.
For gearbox of Agromash Ruslan tractor (ЧН-6), rotation frequencies and relative rotation frequencies of discs of friction clutches are determined in parameterized form, in numerical and graphical expression, which are necessary for determination of basic parameters of shifting process.
Results of tests estimating soil compaction by ВТ-150 tractor equipped with different types of caterpillars are given.
Statistical characteristic of thirteen experimentally obtained typical agricultural backgrounds on two and four ruts are calculated using digital filtering. By spectral and correlation analysis, excitation properties from each background for momentary and operating speeds of machine moving are established.
Application and efficiency of electric traction and electric power take-off of agricultural tractors are considered.
The device containing rigid tray, elastic rubber chute and flexible apron was developed. It is intended for cabbage heads delivery from a combine elevator to a carriage body without damage and with free leaves separation.
Analysis of current state of certain development trends of scientific and technical potential in the area of hydrogen power engineering shows that there are a number of positive conditions for promising development and gradual inclusion of specific types of hydrogen resources into energy use pattern of agroindustrial complex.
Disregard of seed treatment technology results in substantial yield losses and grain quality decreasing. Suggested proportioning device permits to treat corn seeds with encrusting solutions.
Two modifications of adaptive friction clutches of the second generation are investigated. Differences between them are based on using of different methods of feedback gain enhancement.
Materials concerning the most frequently used tribo-compositions are discussed.
The calculation method for V-belt transmission with automatic adjustment of belt tension is suggested.
The method of computer calculation allowing to determine conditions of self-excited oscillations of frame in longitudinal plane is developed. It is applied in the case of moving of tractional wheeled vehicle on even surface with load that causes significant slipping of driving wheels.
Advantages and disadvantages of the second edition of “Tractors and automobiles. Theory and technological properties” textbook by G.M. Kutkov have been analyzed.
