Публікація Determination of destruction conditions for substrates of flexible printed structures(Primedia eLaunch, 2022) Nevliudov, I. Sh.; Zharikova, I.; Novoselov, S.; Nevliudova, V.The results of the destruction conditions determination for polyimide substrates for electronic products are presented. The breakdown voltage for different operating conditions of the FPS has been determined. Using a tensile testing machine, critical levels of mechanical impact on FPS during their operation, which can lead to the destruction of polymer substrates, as well as of printed conductors on them, have been determined.Публікація Development and study of the operation of the module for determining the orientation of the manipulator joint(ХНУРЕ, 2022) Nevlyudov, І.; Novoselov, S.; Sychova, O.In the field of mechatronic systems, manipulators are often used for automated assembly of products, welding, painting parts and more. An important task is to optimize the travel time along a given trajectory of the manipulator. To solve this problem, it is necessary not only to accurately estimate the speed of the manipulator nodes, but also to provide a linear characteristic of the assessment of the position of the mechanism in a wide range of speeds. The matter of the article are methods for determining the orientation of the joint of the manipulator. The goal of the work is to develop a module for determining the orientation of the joint of the manipulator and study its operation in order to determine the suitability subject of the structure for practical use. The following tasks are solved in the article: to investigate the principles of determining the orientation of the joints of industrial robots; choose the design of the orientation determination module; develop an algorithm for determining the position of the joint at any time; perform experimental studies of the position determination module in order to confirm the suitability of the structure for practical use. The following methods used are: experimental research was conducted on a real object - a model of the manipulator joint, created using methods and tools of 3D prototyping; to determine the position of the joint of the manipulator used methods of processing signals received from sensors; processing of experimental results and calculation of values of errors of positioning of a joint of the manipulator is based on methods of the statistical analysis of random sizes. The following results were obtained: the principles of determining the orientation of the joints of industrial robots were studied; the design is developed and the module of definition of orientation of a joint of the manipulator is created; developed an algorithm for determining the position of the joint at any time; the suitability of the design for practical use has been experimentally confirmed. Conclusions: in this paper, two variants of the sensor design are proposed to determine the absolute angle of rotation of the manipulator joint: resistive and magnetic. The proposed design of the resistive sensor was non-technological and much larger than the design of the magnetic sensor. The data obtained in the process of conducting experimental studies of the proposed method of measuring the angle of rotation of the mechanical gearbox of the manipulator joint indicate a fairly accurate determination of the angle using a magnetic sensor. The calculated measurement error was less than 1.4 degrees. The results of the experiment also showed that in addition to the radial direction of movement of the gearbox of the manipulator joint there is a significant displacement along the working plane, and in some cases, such displacements are chaotic. This is due to some defects and imperfections of the surface of the manufactured parts of the joint model used in research.Публікація Development of a software module for operational dispatch control of production based on cyber-physical control systems(ХНУРЕ, 2019) Nevliudov, I.; Yevsieiev, V.; Demska, N.; Novoselov, S.The subject of research in the article is production management processes based on cyber-physical systems. The purpose of the work is to automate the management of production processes using the cybernetic component and analyze the results. To achieve this goal, it is necessary to solve the following tasks: develop an analytical and logical model of the CPPS development management process taking into account the requirements specified in the terms of reference for the development CPPS; to present the analytical and logical structure of connections in the form of a model of interaction of the main windows and all the necessary graphical elements for the implementation of the full-featured interface of the developed CPPS; to carry out experimental researches of efficiency and practical approbation of the received theoretical results, by comparison of classical methods and the developed ones. Results: The targets, physical and cybernetic components of the CPPS development management process were combined in a single information space from the beginning of development to its implementation. The process of checking the achievement of the main goal of CPPS evelopment has been automated, which makes it possible to make changes and manage the CPPS development process at any level and stage of the proposed technology. The process of managing the development of the cybernetic component is automated on the basis of synthesized algorithms of functioning using the GUI elements of object-oriented programming languages, which made it possible to increase the flexibility of the proposed architecture and technologies for automating the CPPS development process and to reduce the development time of the cybernetic component. Conclusions: the proposed models and methods will not only automate the process of managing the development of CPPS from scratch, but will also make it possible to automate the process of managing the development of the cybernetic component for the modernization and improvement of existing CPPS.Публікація Electromagnetic Compatibility Analysis of the Infocommunication Systems Components on the Flexible Structures Basis(2015) Zharikova, I. V.; Novoselov, S.; Nevlyudova, V.; Botsman, O.The design requirements analysis for the infocommunication systems components on the basis of flexible printed circuit boards taking into account their electromagnetic compatibility is performed in the article. The basic parasite parameters of multi-layered printed circuit boards are considered and the recommendations on their diminishing are formulated. Also the information of mechanical actions influence on the electromagnetic compatibility of electronic modules is presented.Публікація Methods of Organizing Communication Between Microcontrollers in the System of Monitoring Energy Consumption(2020) Novoselov, S.; Sychova, O.This paper discusses the principles of building networks based on modern LoRaWAN modems. The basics of implementation of data exchange in these networks are given. Experimental studies have been carried out which showed that in the case of “floating window” it is possible to increase the capacity of the network up to 10…15 packets per second without loss of data transmission speed.
