  • The paper provides formalization and construction of a model of the process of electrical discharge machining. When describing the process, a T-shaped equivalent circuit containing an RLC circuit was used. Determine the transfer function of the proposed substitution scheme. Also, a task is formulated and an algorithm for neural network parametric identification of a T-shaped equivalent circuit is proposed. The problem is posed and an algorithm is developed for neural network parametric identification of the equivalent circuit with a computational experiment, the formation of training samples on its basis, and the subsequent training of dynamic and static neural networks used in the identification problem. The process was simulated in Simulink, Matlab package. Acceptable coincidence of the calculated data with the experimental ones showed that the proposed model of electrical discharge machining reflects real electromagnetic processes occurring in the interelectrode gap.

Development of the technology of systems on a chip for a modern electronic component base ECB

  • 1 Voronezh State University of Forestry and Technologies named after G.F. Morozov

  • Without the creation of Russian technology for designing SoC, it is impossible to provide a modern level of VLSI development, both for defense and civil applications. This is in line with global development trends. Nevertheless, it is necessary to highlight only those essential processes that are most consistent with Russian realities and can help in solving specific problems of the defense industry and the economy as a whole at the lowest cost and in the shortest possible time. The most important element of the implementation of SoC technology is the organization of a single sign-on to locate the production of microcircuits based on this technology. This will allow to drastically reduce costs, to certify the system of complex functional blocks, to increase the reliability and sustainability of developments. Even in organizational terms, this will allow an organized firm (conditionally - Silicon Gate) to be included as a certified chip manufacturer in any contracts with MO. The article discusses the structuring of programs for the development of domestic technology of SoC systems on a chip, the coordination of the SoC area of developments and complex functional blocks, as well as their information support.

  • A detailed narrowly focused survey was carried out on one of the three zones of the technological infrastructure of a specialized facility - a hangar for aircraft (LA). A general list of pollutants (SV) released into the atmosphere at the 2nd site - the hangar of a special facility was established. Generators – installations and constructs of polluting components on a specific area of stationary and mobile type, which operate at a special facility, are fixed in the selected sectors. In accordance with the nature of the released components and the nature of the emission source (stationary or mobile type), the 2nd site is divided into 4 sectors. The measurement by sectors was implemented and the concentration of emissions was calculated according to the recommended regulatory acts of the Russian Federation. Indications of the concentration of a number of substances above the regulated MPC for 2 sectors of the 2nd site for the energy and test site of the special facility have been established. In connection with the recorded results, techniques and procedures of organizational and technical regulations that contribute to minimizing the accumulation of pollutants (gases) of functioning aircraft engines are analyzed and recommended. A method of attenuation of near-Earth smoke at an interval of up to two meters from the surface where aircraft engines operate is proposed based on the analysis of environmental measures at specialized facilities. The method is based on a variation in the orientation of the outflow of gas flows from functioning aircraft engines during launch, taxiing, takeoff, landing, and passage of an aircraft (VS) along the airfield track.

Circuit engineering methods for ensuring ECB resistance to the effects of heavy charged particles

  • 1 Voronezh State University of Forestry and Technologies named after G.F. Morozov

  • The paper considers circuit engineering methods for protecting the electronic component base from the effects of heavy charged particles. One of the main methods is to increase the capacity of the device, which leads to an increase in the capacity of diffusion regions and a decrease in the frequency of single events. The structure of a capacitor is shown, which is connected to various nodes of the circuit to increase the sensitivity of the capacitance of the node. The article focuses on the method of using active RC circuits in the feedback circuit of a storage device cell. The advantages and disadvantages of the methods of using a storage device cell with internal redundancy are noted. The paper shows that the use of circuit engineering methods will provide the required level of fault and fault tolerance to the effects of heavy charged particles.

  • Ключевые слова — Electronic component base (ECB), heavy charged particles (HCP), durability, circuit engineering methods, fault tolerance, single events.

Sensitivity analysis and test results of the electronic component base to the effects of heavy charged particles

  • 1 Voronezh State University of Forestry and Technologies named after G.F. Morozov

  • The work is devoted to the study of the sensitivity of the electronic component base (ECB) to the effects of heavy charged particles. At the same time, the degree of sensitivity is distinguished depending on the functional group of ECB products to the effects of ionization radiation from outer space and on the design and technological design of ECB products. The paper presents the characteristics and conditions for the use of ECB in the radio-electronic equipment of outer space to ensure minimal sensitivity to the effects of ionization radiation and to the thyristor effect. After the sensitivity analysis of ECB products is carried out, a preliminary selection of ECB is performed, requiring testing. The article discusses the criteria for determining the ECB that requires testing and is possible to use without testing. The methods of increasing the durability of radio-electronic equipment of space equipment and the directions of optimization of the methodology of analysis of ECB lists are determined.

Methods for detecting and correcting errors in irregular structures under the influence of heavy charged particles

  • 1 Scientific research institute electronic engineering

    2 Voronezh State University of Forestry and Technologies named after G.F. Morozov

  • The paper considers methods of increasing the durability of radio-electronic equipment in space, namely, methods of detecting and correcting errors during the action of the TCH. Currently, redundancy methods are used to ensure durability, when two or three processors work in parallel in the system, and a special node compares the results of their work. If the results do not match, an error signal will be generated, and the system will begin to perform actions to correct it. The article describes and classifies the main circuit, structural-functional, algorithmic methods for detecting and correcting errors. It is shown that circuit solutions lead to an increase in the crystal area. Therefore, the problem arises of ensuring radiation resistance with a minimum increase in the crystal area.

The paper considers the main components of the approaches of foreign organizations developing radio space technology to ensure its radiation resistance. The design approaches of Thales Alenia Space, Airbus Defense and Space, and the European Space Agency are presented. The article outlines the main directions for optimizing the procedures for the preliminary selection of ECB, which consist in ensuring the required resistance of REE SC at the ECB level with ensuring the reliability of data on durability, in minimizing the costs of applying resistance enhancement measures (through the use of a promising ECB with increased resistance characteristics), to replace ECB.

  • These technical conditions of multi-apartment buildings are a huge digital array for making important management decisions both within the boundaries of individual territories of the municipality, and for planning budget expenditures within the municipality, the subject of the federation and the country as a whole. Aspects of the formation of data on apartment buildings in various information systems are considered. The basics of ensuring the reliability of the presented data are considered. It is noted in the work that for many years, during the transition from a planned economy to a market economy, the requirements of technical regulations and normative documents for the maintenance and operation of apartment buildings are not fully complied with by the operating organizations. The deadlines for replacing systems and equipment that have worked out the deadline are not met. It is noted that federal legislators and the Government of the Russian Federation have not determined a general procedure for monitoring the technical condition of apartment buildings and have not formed a general approach to assessing their technical condition, the obligation of owners of premises of apartment buildings to finance these works, their frequency has not been determined. It was revealed that the data obtained during the monitoring of the technical condition of apartment buildings combined in federal and regional information systems would be an objective marker in the formation of state and municipal programs in the field of reducing the housing stock unsuitable for living. financing of monitoring.

  • The guiding principles of project implementation are planning. The discrepancy in time, cost, and quality between the plan and the actual implementation of the project requires management decisions supported by an analysis of the optimization of the duration of the project and the search for reserves to reduce the implementation time. For this purpose, a basic PERT model for a specific project was developed, early and late deadlines for work, time reserves, and a critical path were calculated. This work is aimed at applying methods of evaluation and analysis of projects to find optimal solutions and control the efficiency of time and costs in project planning, by varying the work on the project and the executors of the work. The results of this study showed that there are quite large time reserves for works 5-7, 7-9, 6-9, etc., which makes it possible to redistribute work between performers and allows you to vary performers during the implementation of several projects simultaneously.

  • The features of software development using static and dynamic arrays in the C ++ Builder object-oriented environment are considered. The syntax of various options for creating static and dynamic arrays in the C ++ Builder language is considered in detail. Examples of working with static and dynamic arrays in C ++ Builder developed by the authors and the corresponding algorithms are presented in the form of block diagrams, program codes and program interfaces. Examples of program development are given using one-dimensional and multidimensional arrays. Examples of memory allocation are given for dynamic arrays. The choice of the required method for solving the problem is substantiated, taking into account the available input data and taking into account the expected results, as well as the peculiarities of their obtaining and processing. The external specification and the main features of the solution of the assigned tasks are considered. The development of algorithms and programs for solving problems using arrays in the C ++ Builder environment is the basis for solving engineering and technical problems using software on a computer. The proposed approaches can be used in practice, since the algorithms outlined in the work will serve as a complex example in solving the set engineering and technical problems.

  • 1 Voronezh State University of Engineering Technologies, This email address is being protected from spambots. You need JavaScript enabled to view it.

  • In the realities of the pandemic, chat bots have become indispensable helpers. They do not need a lot of resources and constant human control. A method of interacting with social networks through a specialized software interface Web API, which is the basis of the REST architecture, is considered. The basic structure of requests for receiving and sending data to servers is presented. On the example of the implementation of a chatbot for vk.com, capable of automating a dialogue with users, the main design stages are presented, including the requirements for the implementation and operation mode based on the client-server architecture, implementation and testing. The project server is implemented on a Raspberry Pi4 single-board computer. Demonstrated code for performing basic queries and implemented a Long Polling approach to continuously track and distribute user messages. Methods were formed to obtain the necessary resources from the server, to declare a new resource on the server, to update information on the server, and to delete certain objects from the database. The result was a patented software product "Intelligent assistant of VSUIT for social networks".

  • The need to maintain the technical condition of buildings with a significant service life determines the regularity of their inspection. The paper presents the analysis of the results of the inspection of the building of the repair and operational block of the compressor station. The analysis of the design documentation and the results of the measurement work showed that the construction is a one-story basementless building with dimensions of 54.62x18.74x5.9 m. The performed visual examination showed the presence of damages and defects of the third and fourth categories, which requires certain actions to eliminate them. Visual examination showed the need for instrumental examination. In particular, the need to determine the strength of brickwork and the strength of concrete in structures. The analysis of the results of the instrumental examination showed: the results of testing the wall masonry by the shock pulse method using the ONIKS 2.5 device showed that the compressive strength grade of silicate and ceramic bricks of the walls of the repair and maintenance block corresponds to M100, and the grade of masonry mortar is M50; The results of concrete testing by the non-destructive method of strength control in accordance with GOST 22690-88 with the Digi Shmidt 2000 device showed that the class of concrete in terms of compressive strength in reinforced concrete slabs of the covering of the repair and operational block corresponds to B20, and the class of concrete in reinforced concrete beams of the covering corresponds to B25. The verification calculation showed that the strength of the reinforced concrete pavement of the repair and maintenance unit under the full design load acting at the time of the survey was ensured. The analysis showed that the technical condition of the maintenance and operation unit is of limited serviceability. The work provides recommendations for eliminating defects and damages.

Determination of control actions and energy consumption during programmed motion of the manipulator

  • 1 Voronezh State University of Forestry and Technologies named after G.F. Morozov, This email address is being protected from spambots. You need JavaScript enabled to view it.

  • The paper presents the modeling of the solution to one of the problems of mechanics - the automated control of the manipulator used in the forestry industry for moving operations at various stages of the technological process. A unified model has been developed that allows generating control actions and energy consumption of the object under study. As a result of solving the problem, a system of equations was obtained for determining the control moment and control force, which allow the manipulator to be set in motion, as well as to determine the energy consumption for the implementation of the program motion, in which the load moves at a given speed from point a to point b along a straight line inclined at a given angle to the horizon. The proposed algorithm is generalized for solving computer-aided design problems and is a simulation experiment. The software solution is implemented in two forms. In the first module, the database is filled with the initial metric, angular and physical and mathematical characteristics of the manipulator. In the second, according to the unified model described above, the indicators are calculated that are necessary for the movement of the object and characterize the dynamics of movement, as well as the necessary energy consumption for performing the operations performed. The possibility of converting the calculated values from the database into an MS Excel table is provided.

  • The theoretical propositions of the algebra of logic are considered. It is noted that the current microcircuitry based on the algebra of logic contains logical statements: true (yes) is a logical unit, false (no) is a logical zero. Based on the given logical function: ((ABC)×D + A×(BCD) + A×(BC)×D + (AB)×(CD), frontal, minimal, transformed minimal variants of the combination device are implemented, as well as minimized variants in the bases "AND-NOT" and "OR-NOT". A combination device based on import-substituting chips of 155, 176 series has been designed. The analysis of the obtained devices is made from the standpoint of technical and economic indicators, in particular, an assessment of the number of logic elements used, an assessment of the symmetry of the structure, as a result, a reduction in energy consumption, an increase in performance, improvements in parameters for reliability of functioning, a decrease in weight and size characteristics. Assuming that the law of change of the information parameter U1 is close to linear, taking into account the effect of temperature as boundary values for the elements of the applied microcircuits, taking the values -60 °C and +120°. Accordingly, the parametric reliability of the optimal implementation of the device according to the output voltage parameter is calculated. The conclusion is made about the inverse dependence of parametric reliability on temperature growth. A recommendation is given when evaluating parametric reliability for a number of other information parameters about the need to take into account both the number of chips used and the type of their interconnections.

Simulation of oscillatory processes in the MVSTUDIUM package

  • 1 Voronezh State University of Forestry and Technologies named after G.F. Morozov

  • The mathematical model and algorithms of oscillatory movements are considered. Various factors affecting the oscillatory process are considered. Oscillatory movements are constructed in the MVSTUDIUM modeling environment. The schemes of three computer models demonstrating oscillatory processes are determined: a model of a pendulum with a non-movable suspension point, a model of a pushing pendulum with friction force and a model of a breaking pendulum. Classes are being built to execute models with embedded properties, as well as with the ability to export the created classes to other models, and embed classes created by the program developer into the model. Creation of 2D and 3D models of oscillatory processes, an experiment behavior map and a virtual stand.

  • Ключевые слова — Oscillations, model, MVSTUDIUM environment, 2D and 3D animations, systems of equations, virtual stand, model behavior map.
