Abstract
It is known that a large share of the costs in perennial plantings of fruit and berry crops is associated with weed control. In the ranks of plants, chemical methods of weed control using herbicidal rods are used. In recent years, requirements for uniform distribution of herbicides on the treated surface have increased. The article analyzes the accuracy of the dosage of herbicides in the intercustal zone with a bar with a deviating section. The movement of the rod in the horizontal plane and the spill of liquid along its length is considered. The volume of the poured liquid, the area of the wetted surface, the amount of liquid per unit area are determined. It was established that the dose of application of herbicides over the area depends on the speed of the bar, the angle of its inclination to the direction of movement and the specific spill of the liquid along the length. It is shown that the more the rod deviates from its initial position and the closer it is to the row line, the greater the spout of the solution per unit area with respect to a given one. Dependencies are obtained that allow one to compare the doses of the application of the working solution of the herbicide on the treated surface before the bar meets the cultivated plant and when it is bypassed. The paper shows the data of calculation of the spill of the working fluid at a specific point of the rod. It was revealed that during the processing of the inter-brush strip in one pass with the half-line deviating section of the row line overlapping, the excess of the given outflow dose can reach 20 times. To process the inter-bush zones of perennial plantations, it is recommended to stack the herbicidal booms with short deflecting sections up to the row axis, providing compensation for inaccuracies in driving and planting trees in a row, and processing the row in two adjacent passes.

Published: September 2020

AbstractContinuous improvement of the design and parameters of engines is possible only with a thorough study of the processes occurring in them. The development of engine theory is also not possible without setting up increasingly complex, precise, and sometimes unique experiments and research. Research and testing of diesels is one of the main means of checking the quality of manufacturing parts and Assembly units, components and the engine as a whole, the correctness of its installation, compliance of the main characteristics of the diesel engine with the requirements of technical documentation. Putting diesel into production is preceded by a number of stages for the development of normative and technical documentation, including design, technological, as well as for the production, research and testing of the main and subsequent samples. Development and commissioning of diesel engines for production and types of their tests are regulated by state standards, which establish the procedure for acceptance and requirements for the technical level of diesels. After acceptance and commissioning of engines for production, the improvement of their designs and technical and economic indicators does not stop. In this regard, the diesel engine must pass certain types of tests that are standardized in terms of terminology and definition of basic concepts.

Abstract
The article proposes a method for improving the quality of cold straightening of non-rigid shafts. The essence of the solution is to change the sequence of traditional technological operations by introducing dynamic straightening of the workpiece with subsequent application of a given depth of the deformed layer, immediately before roughing and finishing, and after them, in addition, in the process of roughing and finishing, the depth and nature of stresses are preserved. due to the exclusion and redistribution of surface stresses arising directly in the process of machining non-rigid parts, taking into account the changing dynamic characteristics of the cutting process itself. A complex functional diagram of the automatic control system has been developed. The results of straightening a non-rigid shaft, without a system and using automatic control, are presented. Decrease of processing error by 2..3 times is shown.

Research of the transient processes for discrete control systems
Authors: Kassimova B R , Sadvakassova A U , Sansyzbay L Zh 
Published: September 2020

Abstract
The dynamic characteristics of discrete systems, as in the theory of continuous systems, include transfer functions, time (impulse, transient) and frequency characteristics. When determining time characteristics, a single discrete impulse and a single discrete function are used as typical signals. The transient characteristic of a linear discrete system is the response to the single discrete function under zero initial conditions. The study of discrete systems begins with an assessment of their fundamental operability, that is, stability. The stability of continuous linear systems is determined by the behavior of the transient component of the general solution of a homogeneous differential equation of the system under study. Similarly, the problem is solved for discrete systems described by linear difference equations. A discrete system is called stable if the transient process tends to zero over time. The analysis of the discrete control system on the stability and accuracy of the transient process is conducted. Conclusion: in a discrete system stability, accuracy and control quality depend on the parameters of the gain system and the time.

Published: September 2020

Abstract
An object of research of article is the friction coefficient at refining of fibrous semi-finished products in the knife refining machines. The main consumed energy of these machines is spent for overcoming friction of rotor about stator. On the basis of the theory of contact interaction of knives the tangential coefficient of friction between rotor and stator is investigated. This coefficient depends on type of friction of rotor and stator, concentration and type of fibrous semi-finished product, pressure in an interknife gap, the given module of elasticity of material of plate, the area of contact and speed rotation of rotor. Recommendations for decrease in power consumption of process of refining are developed.

Authors: Rastorguev D A , Sevastyanov A A 
Published: September 2020

Abstract
The paper considers the solution to the problem of developing an algorithm for automatic classification of the processed surface quality on the example of hard turning of 105WCr6 steel. The input data for the algorithm are digital photos obtained on a metallographic optical microscope “Labomet” with an x4 magnification. The developed algorithm successfully solves the problem of binary classification, where the classes are groups of samples with high (acceptable) and low (unacceptable) quality of the processed surface. The algorithm is based on the search for a template corresponding to a characteristic defect in hard turning on a converted digital image of machined surface. The results can be used to automate scientific research.

Published: September 2020

AbstractThe work is devoted to the study of possible layout options for various soil-throwing machine-tractor units using the 3D-CAD SolidWorks system. In the process of research, three basic mass-produced models of wheeled traction devices were selected. This is the T-150K tractor, the DZ-122 grader and Amkodor 2661-01 forwarder. Its simplified 3D models were created, while all the basic geometric parameters were saved. At the next stage, the mass-inertial characteristics of the main moving elements were set by applying the properties of materials from standard libraries to it. These are wheels, suspension elements, linkage mechanisms of working equipment, front and rear frames. To compensate for the mass-inertial characteristics of the stationary elements located on the front and rear half-frames, spherical elements were added, with the possibility of changing the spatial position and mass. To study the possibilities of aggregation, simulation 3D models of three types of soil throwers were created: heavy mounted, mounted medium, light manipulator. Also, various types of additional tillage equipment were modeled: stripper harrows, strip cultivators. Next, ten versions of the most promising soil-throwing machine-tractor units were arranged. The coordinates of the center of gravity of the aggregates and the mass-inertial characteristics were obtained and analyzed. In the future, the developed models can be studied on static and dynamic virtual stands using the methods of multibody dynamics (MBD), for example, in the integrated environment for engineering calculations SolidWorks Motion, or exported to specialized programs, for example, MSC.ADAMS.

Abstract
One of the main difficulties in combating forest fires with conventional water-based methods is the difficult topography and the fact that there are usually no accessible roads to bring firefighting techniques closer to the fire site. Today, a large number of scientific teams are working on the topic of extinguishing the edge of a forest fire with soil. The aim of the study is to increase the efficiency of forest fire prevention and extinguishing by ground-throwing machines by removing the upper combustible layer of forest soil, the formation of a loosened soil shaft from the mineralized layers of forest soil and throwing soil into the edge of a forest ground fire. The paper briefly describes the technical means for extinguishing forest fires using soil. The analysis of the structures of soil-throwing machines has been carried out. The promising directions for improving the technology and working bodies of fire-fighting ground launchers are described, the advantages and disadvantages of its designs are revealed, and ways of further improvement are outlined. A promising design of a strip-laying soil gun with a hydraulic drive of working bodies for preventing and extinguishing forest fires is presented. A distinctive feature of the developed design of the strip-laying soil launcher is the use of an auger to remove the upper fire-hazardous cover, consisting of plant residues, and cut spherical discs to improve the quality of loosening the soil shaft. As a result of the conducted studies of the working process of the strip-laying machine, it was found that the share of the soil covers with combustible materials in the soil flow decreased from 40 to 7%, and the quality of soil shaft loosening increased by 17%, due to which the average distance of soil ejection increased from 10 to 15 m and the power consumption of the rotor-thrower is reduced from 12 to 10 kW.

Published: September 2020

Abstract
The formulation and solution of the problem of determining safety stocks in a linear technological chain consisting of suppliers in a network structure is considered. It is assumed that the conditions for the production of suppliers in terms of throughput are quite sufficient to ensure deliveries on time in the required volume. The allocated volume of resources in the supplier’s production system for these purposes cannot be predetermined precisely. It is a random variable that changes in a certain interval, which is actually confirmed statistically. Reducing losses from downtime of technological equipment is ensured by the creation of reserve stocks. For solving the problem the method of dynamic programming is used, which allows one to determine the optimal values of safety stocks analytically.

Published: September 2020

Abstract
One of the classical problems of the theory of pattern recognition is to reduce the dimension of the original feature space from dimension N to dimension N’, N’ < N. In the first works on pattern recognition, the task was to construct an informativeness criterion that maps N-dimensional to a space of lower dimension so that a solution can be made in this space. One of the advantages of this criterion is that the classification in a space of lower dimension is faster and easier, and the criterion of being constructed once.
