AUTOMATED DESIGN OF PARAMETRIC THREE-DIMENSIONAL PARTS BASED ON THE APPLICATION DEVELOPMENT FOR WORKING IN KOMPAS-3D
Аннотация
The paper presents a method for automating a portion of a drafter’s work during the parametric 3D model design phase, by using a developed application for KOMPAS-3D. Designing repetitive parts consumes a significant amount of time; therefore, the author has developed a program that enables applying parameterization mechanisms for the automatic creation of a 3D model of a prototype blank. The automation process involves using the created KOMPAS-3D application, which allows parameters that form the 3D model to be manipulated through a variable input window. The developed program aims to eliminate the user’s interaction with Boolean operations and sketches, and to create an application library for standard parts. The developed application, which automates the 3D model creation process, is implemented using the Python programming language and the KOMPAS-Macro application. The paper demonstrates the proposed method for automating the design of parametric 3D models of prototype blanks, through automated creation of the parametric 3D model, using the example of designing a “glass” part. To evaluate the effectiveness of this method, the author conducts a comparative analysis of the time spent modelling this part using the traditional method with Boolean operations, and using the developed program. The results show that the drafter’s time spent creating the 3D model of the proposed part is reduced several times over using the automated method. Modelling the process of automated design of a parametric 3D model of a prototype blank, based on the proposed algorithm, is implemented using the graph theory. This method can be useful for a programmer-engineer with experience in Python programming and skills in developing design documentation using the mechanical engineering configuration of KOMPAS-3D for creating their own embedded application library, as well as for a design engineer who solves problems to ensure the technological sovereignty of the country.

AUTOMATIC CONTROL OF DEBURRING MODULES IN A MACHINE FOR THE MECHANICAL EDGE PROCESSING OF SHEET METAL BLANKS
Аннотация
This work addresses issues related to controlling the mechanical edge processing of sheet metal blanks, specifically their deburring. The necessity of the deburring operation is due to the low surface quality of sheet material, which leads to both a reduction of finished product quality and additional material and time costs for correcting defects. Therefore, the task of developing an effective control algorithm for deburring modules is highly relevant. An analysis of the time costs of the deburring machine technological process in a real-world production setting has shown that the main costs are associated with deburring sheet material itself. The authors propose a design for a deburring machine and an algorithm for the automatic control of its modules. The developed scheme for taking readings and registering deburring wheel wear allows for the real-time registration of technological process parameters and the correction of the wear process of the abrasive deburring wheel, which is the main element of the deburring module. The authors have established that the total length of the working surface travel of the deburring wheel can be useful to predict wear, and the critical diameter of the deburring wheel can be applicable to limit its maximum usable diameter. Based on this, the work has proven that the control algorithm for the machine deburring module of the sheet metal blank edge cleaning should include a block implementing feedback on the abrasive wheel diameter, ensuring a constant cutting speed. Additionally, predefined parameters for the material removal process, based on the drive current value at a constant cutting speed, allow for ensuring the quality of the deburred sheet surface.

ANALYSIS OF DEVELOPMENT ISSUES FOR A VOICE ASSISTANT FOR SPECIALIZED LIBRARIES
Аннотация
The paper examines the issue of serving readers with visual impairments in specialized libraries, and the challenges these readers face. Existing standard automated customer service systems turn out to be less than fully functional due to the population’s specific needs. The work suggests developing a voice assistant integrated into the library’s existing automated service system; presents an application operation model, taking into account the specific methods for converting text into numerical formats. The authors develop an algorithm for the voice assistant’s operation, including the stages of user authorization and registration, notifications of new book arrivals, recommendation generation, and notifications of overdue materials; provide the structure of the library’s database for visually impaired individuals, with all the relationships that ensure ease of information retrieval. The authors illustrate the implementation of the application core functions, developed for the N. Ostrovsky specialized library in the city of Kaluga, serving people with visual impairments. This will improve the organization of information storage and delivery; optimize workflows, and increase accessibility and application for users with disabilities.

DETERMINING THE NUMBER OF CRITERIA FOR EXPERT RATING OF ANALYSIS OBJECTS OF INFORMATION TECHNOLOGY PROFILE
Аннотация
The aim of this work is to determine the functional relationship between the quality of the rating procedure for difficult-to-formalize objects of analysis (DFOAs), which include innovative information technology proposals, and the number of evaluation criteria used. The authors consider the content of these criteria as a necessary condition for the effectiveness of the DFOA rating procedure, while their formalized and justified quantity constitutes a sufficient condition for its efficient execution. The objectives of the study include modelling the probabilistic reliability of the criteria-expert evaluation (CEE) procedure for the predictive rating of DFOAs and identifying the interrelationships between its identification parameters. Furthermore, the authors consider this algorithmized CEE procedure for various DFOAs, which include the predictive quality of innovations, a significant component of modern information technologies, where the functionally creative capabilities of neural networks are increasingly used. This is the main perspective for developing the qualimetric approach to DFOA rating proposed in the article. The research methods are based on the apparatus of applied qualimetry of DFOAs and the theory of complex system reliability. This enabled the analytical derivation of a relationship between the set of conditional covariances of individual quantitative values of the evaluation criteria and the coefficients of their influence on the final DFOA rating, such as the predicted level of potential effectiveness of a specific innovative technological proposal. The key new result of the research is determining the functional dependence of the probabilistic reliability of the rating procedure on the information content of the evaluation criteria used and their total number. The resulting general probabilistic relationship made it possible to link the predicted reliability of the CEE procedure with the informational content of the applied evaluation criteria and their total number into a unified functional-probabilistic complex. Using the Pareto principle, this relationship is transformed into a calculation dependency, according to which it is realistic to determine a specific number of evaluation criteria depending only on the requirement for their reliability, namely the probability of an adequate representation of the corresponding quality characteristic of the rated DFOA. The paper provides typical examples for calculating the sufficient number of evaluation criteria at various levels of requirements for their content adequacy. This allows for quantitative formalization of the DFOA rating structure, which includes various innovations of information technology content.

MODEL FOR ESTIMATING THE DURATION OF GROUP TRAINING CONSIDERING ORGANIZATIONAL RESOURCE CONSTRAINTS
Аннотация
The article considers the issues of mathematical modelling of the processes of specialists’ group training for joint actions, which is in demand in emergencies. The efficiency of training a specialists’ group in these conditions is a key factor in increasing the entire group efficiency. Therefore, the authors choose the total time of joint training of a specialists’ group as the main criterion. For this purpose, they develop a model for assessing the group training duration, which takes into account the resource constraints of educational organizations that can potentially carry out specialists’ group trainings. The model includes the following stages: determining the competencies in the process of training (retraining) a specialists’ group, determining training courses for a specialists’ group, and selecting an educational organization to ensure training a group in the minimum time. The article also contains a numerical example illustrating the application of the developed model using the example of training a conditional group of two specialists with different initial and different required competencies. The example considers three educational organizations in which training (retraining) a specialists’ group is potentially possible, and the educational organization is selected in accordance with the developed model.

ANALYSIS OF TIME AND FREQUENCY ERROR OF SYNCHRONIZATION SIGNALS IN DIGITAL TRANSMISSION SYSTEMS
Аннотация
The aim of this study is to generalize approaches to analyzing the error of phase fluctuations of the synchronization signal in information transmission systems. The objective is to refine the methodological framework for calculating time and frequency error. The research methods include comparative analysis combined with an analysis of domestic standards and international recommendations related to measuring synchronization signal inaccuracy due to the influence of interference and noise in digital communication channels. The work presents the main calculation rela-tionships for the inaccuracy indicators of reference generator signals. Examples illustrate the procedure for their calculation and analysis, as well as the process for determining compliance with standards. The presented parameters of frequency error include Allan deviation, modified Allan deviation, time deviation, root mean square (RMS) of time interval error, maximum time interval error, and the frequency error parameter: relative frequency deviation over a period longer than 7 days for synchronization signals at the outputs of primary reference generators. Findings state that the assessment of compliance with frequency stability standards of the synchronization signal is performed for four types of frequency offset of the input reference signal from the nominal frequency: free-running mode, minimum static tracking range, dynamic tracking range, and capture range of the slave devices.

OPTIMIZATION OF THE ASYNCHRONOUS TRAC-TION DRIVE OF A LOCO-MOTIVE BY REDUCING THE TEMPERATURE OF THE ELECTRIC MOTOR ROTOR WINDINGS
Аннотация
On freight locomotives, asynchronous traction drives operate under heavy-duty conditions with limited cooling intensity, which contributes to overheating the windings and thermal breakdown of their insulation. Therefore, a more detailed study of the thermal state of the traction asynchro-nous motor is necessary, as well as of the methods to prevent its overheating, which leads to rapid wear of the rotor windings and their insulation. Conse-quently, a key task is to determine the influence of the rotor slot shape, which in turn defines the cross-sectional area of the winding bars on the thermal state of the traction asynchronous motor. Based on the research analysis of domestic and foreign scientists, various cross-sectional shapes for the rotor winding bars are considered, such as rectangular, trapezoidal, blade-shaped, pear-shaped, and bulbous ones. For each cross-section of the bars, the authors calculate thermal performance indicators, based on which they propose an optimal cross-section variant that will reduce the temperature of the rotor windings during operation of the traction asynchronous motor.
