Development of a control system with fuzzy tuning of values for the actuation setpoint
Authors: Solovjev D S , Solovjeva I A , Konkina V V 
Published: December 2020

Abstract
The article discusses the disadvantages of using fuzzy logic to correct the value of the PID controller coefficients in control systems. The disadvantages are related to the actuation setpoint, which knowingly doesn‘t provide optimal control during its implementation at the control object. It is proposed to use a fuzzy tuning of values for the actuation setpoint in the control system circuit based on the deviation between the measured values of the input action at the control object and the values accepted in the calculation by the mathematical model. Fuzzy tuning of values for the actuation setpoint provides that the control objects achieve the desired indicators without re-solving the optimization problem. The effectiveness of the proposed approach is demonstrated by the example of developing a control system for the electroplating process.

Application of OLAP-technology in decision support system for enterprise management
Authors: Akhmedyanova Gulnara F 
Published: December 2020

Abstract
The work is devoted to the study of methods for increasing the profitability of an enterprise based on management decisions that are close to optimal. It is shown that the enterprise, as an abstract control object, integrates at least four components: buildings, facilities and utilities, production facilities, financial and material stocks and personnel. Moreover, each of these components of the production system has its own management system, and enterprise management, therefore, is carried out at the second level of the hierarchy. Since the levers of direct control of the production system are managed by the first-level control systems, parametric, structural and organizational changes become the control actions at the second level and the main tasks of management are the competent redistribution of managerial resources between these influences. Relying on the presentation of information in the form of a hyper cube and taking advantage of the fact that all solutions lie on the plane of equal contributions, and then, taking it as the coordinate plane for counting the utility function, one can reasonably find points on this plane with a resource distribution close to optimal by maximizing this feature.
Principle of constructing flat designs of electronic circuit diagrams considering forbidden figures
Authors: Potapov V I , Suskin V V , Filatkin S V 
Published: December 2020

Abstract
The problem of designing double-sided printed circuit boards in the form of synthesis of flat structures of electronic circuit diagrams at the design stage is considered. The aim of the work is to arrange the connections on two sides of the printed circuit board without jumpers, which facilitates the conditions for routes to any tracer of modern design programs. The main drawback of all the algorithms used is the principle of sequential and fragmented viewing of the commutation space incorporated in them. To solve this problem, it is necessary to use the graph theoretical method, rather than the topographic method, where priority is given to the metric aspect of the problem. The graph theoretical method involves preliminary stratification of the graph on two sides of the printed circuit board and analysis of the planarity of the graph circuit with subsequent elimination of jumpers, assigning a conflict link of the route to the back of the circuit board.

Modeling of the stressed-deformed state of the apparatus under pressure at corrosion
Authors: Rubtsov A V , Kulakov P A , Arkhipova K S 
Published: December 2020

Abstract
Vessels and apparatuses operating under pressure at hazardous production facilities are operated under conditions of many factors that limit the safe service life. These factors include elevated pressures and temperatures, damage during operation, exposure to both static and cyclic loads, etc. The most common and determining damage to metal equipment is corrosion wear. Corrosion wear negatively affects reliability during operation, gradually reducing the strength of the technical device by reducing wall thicknesses and thereby bringing the object closer to its ultimate state. As a rule, visual inspection and thickness measurements make it possible to identify corrosion zones, analyze these zones and give recommendations for further operation or replacement of defective areas. However, some designs of vessels and apparatuses do not give the opportunity to carry out work on the assessment of the corrosion state in full, and in this regard, there is a possibility that adverse sections will be skipped. Especially such problems arise when diagnosing devices with multiple workspaces. Currently, the work on modeling equipment of this type with the use of specialized software systems for assessing the stress-deformed state taking into account all the factors present and identifying the most unfavorable zones with maximum effective stresses is relevant. In this paper, we study the interconnection between the effect on the apparatus with a shirt of operating parameters when modeling various scenarios of corrosion wear.
Improving the reliability of hydraulic systems of technological machines
Authors: Pugin K G 
Published: December 2020

Abstract
Modern technological machines have in their design hydraulic systems that are used to control the working body of the machine. Currently, hydraulic systems are complex systems that consist of a large number of subsystems and separately functioning elements. An analysis of the reasons leading to the failure of hydraulic systems shows that their reliability depends on a large number of factors, which are often interconnected. These factors include the external influence of the environment, the properties of materials and working hydraulic fluid, wear processes, the magnitude of the loads, the operating time, as well as regulations for the maintenance of the hydraulic system as a whole and its individual elements. As the statistics of hydraulic systems failure show, about sixty percent of failures are associated with contamination of the working fluid. It is possible to prevent contamination of the hydraulic system at the design stage or by changing the organization of maintenance. It is shown that the number of sensors registering the level of contamination of the hydraulic fluid and their placement on the machine body must be scientifically substantiated. The studies presented in the article allow us to make a conclusion about the possible formation of stagnant zones in remote nodes of the hydraulic system. An important result of this research is that dynamic data collected by the built-in particle detection sensors can give inaccurate information about the condition of the hydraulic fluid. Evaluation of modern methods of technical operation has made it possible to identify a priority condition that will allow the transition from diagnostic to predictive assessment of the state of elements of hydraulic systems of technological machines.

Published: December 2020

Abstract
An improving methodology for assessing the level of localization of the production of agricultural mobile energy is presented. The basic methodology has been substantially adjusted with the transition from an arbitrary list of obsolete technological operations to the valuation of modern technologies, the quantitative accounting of the scarcity of manufactured equipment, the volume of after-sales services, the development of research and development, operational provision of spare parts, etc. The localization level sufficient to recognize a particular model as being produced in Russia is calculated as the sum of the shares of the tractor cost, taking into account a number of decreasing coefficients that take into account the progressive effect of localized production: deficiency coefficient of the produced model; service network ratio; R&D financing ratio; coefficient of availability of spare parts warehouse. The implementation of this methodology contributes to solving the problems of developing the Russian economy.

Published: December 2020

Abstract
The article gives an outline of the development of a method for sowing row crops and the design of a ridge seeder for its implementation. The use of the latter makes it possible to carry out the pre-sowing cultivation in one pass, the sowing of seeds in a moist soil layer on a compacted bed. It also helps to form a soil hummock of the required size above the seeds and by rolling the soil hummock from three sides one can finally form a ridge of the soil of the required size and density. The optimal diameter of a flat disc of the working part in the ridge seeder has been theoretically and experimentally substantiated proceeding from the conditions of its reliable rotation in the soil with minimal sliding and rolling resistance, as well as cutting soil clods, weeds and pushing the soil from the inter-row space on to the sown seeds.
Theoretical and experimental substantiation of the amplitude and source of oscillations on a container of an acoustic butter churn
Authors: Lazutkina Svetlana , Zykin Evgeny 
Published: December 2020

Abstract
A method has been developed for butter production and a unit for its practical implementation which makes it possible to use oscillations efficiently at the macro level for the vibration of a container with cream, and at the micro level for the effect of oscillations on milk fat globules until the desired butter granules are obtained. The experimental studies of the proposed butter churn in laboratory conditions have shown that the optimal frequency for churning butter should be 5 Hz. In order to reliably estimate the number of oscillating actuators and their lay-out on the container surface of a butter churn it is necessary to take into account the motion trajectory of the fat globules which can be simple and complex. To ensure the complex motion trajectory of fat globules, a method has been developed for butter production and a unit to implement this method which gives a possibility to use oscillations in the most efficient way at the macro level for the cream container vibration, and at the micro level for the effect of such oscillations on fat globules in order to obtain butter granules. Analysis of the research results showed that butter corresponding to GOST was obtained at a frequency of 5 Hz and an amplitude of oscillations of the cream container in 5 mm.

Published: December 2020

AbstractThe article presents the analysis results for the parameters measurements of the rail track and the ratio between values of the vertical and side wears of rails in curves of different radii under different operating conditions. It is shown that the installed elevations of the outer rail do not meet the contemporary requirements in increasing the efficiency of the track while minimizing the rail wear. At the second stage of the research, various sections were examined by type of traction, technical equipment, plan parameters and the longitudinal profile. As an example, the results of calculations are presented in Lviv-Rava-Ruska section as a promising project that can ensure the integration of railway transport in Lviv-Warsaw direction. Analysis of the results obtained with the help of the software package – MoveRW and RWPlan programmes, allowed to determine such a combination of elevations of the outer rail in curves, so that trains of different categories realize the lowest values of cross unbalanced accelerations, which provide the minimum wear of rails in compliance with regulatory requirements for unbalanced acceleration, changing this acceleration in time, elevating speed of a wheel on the removal of the outer rail.
