TOOLS FOR DEVELOPING MECHANICAL ENGINEERING PRODUCT DESIGN
摘要
To enhance the competitiveness of domestic machinery mechanical engineering, to reduce excessive diversity in component parts and production components, as well as to address challenges related to digital transformation of production processes, new efficient business processes for product creation are required. Improving quality, technological sophistication, and operational efficiency of the parts depends on their design perfection. To solve design tasks, the author proposes three main tools namely coupling nodes, mobility matrices, and gaps between component parts of a product. Using these tools within the framework of group design methodology allows developing customized products with low costs per unit produced and will contribute to solving the task of digitizing business processes. Being the most general concepts that reflect what is inherent in any product, the proposed tools can help formalize the process of “inventing” a construction. The paper illustrates applying the proposed tools by an example of modernizing the design of a movable connection. In the original product, a moving part must be replaced with another type of structure. As a result of the project work, it is established that this requires introducing an additional component and designing its structure.

METHODOLOGY FOR TESTING MEDICAL ROBOT AXES USING MULTIFACTORIAL TESTS WITH AN INERTIAL TEST BENCH
摘要
This work aims to develop a methodology for multi-factor testing of medical robot axes using an inertia test bench, which consists of a mechatronic module under test connected to a load mass driven by a motor through an electromagnetic clutch, along with a force-torque sensor and two optical position sensors. During the conducted experiments, the authors determine the characteristics of nominal braking parameters, as well as relationships between brake process parameters and given velocity and magnitude of external moment of inertia; collect data from the sensors and process it by an STM32 board, then record it in a text file format (.txt). Based on these findings, further adjustments can be made to the design parameters of the mechatronic axis module of a medical robot to modify its functional dependence and improve device performance.

SIMULATING THE DESIGN PROCESS FOR PARTS MANUFACTURED USING ADDITIVE TECHNOLOGIES THROUGH CREATING AN IMITATION PRODUCT MODEL
摘要
The continuous development of information technologies and automated design systems contributes to increasing automation levels in product design across various industries. One important stage in the product life cycle is creating prototypes. Currently, additive manufacturing techniques and 3D modelling are widely used for prototype production. However, when employing such methods, it is essential to consider material properties of plastics, particularly shrinkage, which affects the dimension of the prototype product. Shrinkage influences actual sizes of parts produced via additive processes compared to their initial designs. Therefore, the research aimed at developing a simulation-based computer model that accounts for factors influencing prototype fabrication accuracy becomes relevant. This study investigates key parameters affecting dimensional deviations from predefined values specified in CAD models. These include filling density and deviation from nominal dimensions. Based on the obtained values of the parameters under study, the authors develop a mathematical model enabling prediction of size variations depending on filling density. This simulation model will facilitate creation of 3D prototypes incorporating compensation for plastic shrinkage, thereby enhancing precision in producing components using additive manufacturing.

SIMULATION OF EMERGENCY OPERATION OF VEHICLE GEARBOX VARIATOR
摘要
The relevance of the work stems from the necessity to ensure reliable functioning of a continuously variable transmis-sion (CVT) under emergency conditions, particularly when the hydraulic control system fails. The aim of the study is to define the operational characteristics of a chain-type variator of CVT without hydraulic control. The method of the work is computer modelling of the chain variator. The novelty of the work lies in utilizing a discrete contact model between the chain and conical pulleys of the variator, accounting for variations in friction parameters. As a result, a computer dynamic model is developed to evaluate the performance characteristics of a chain-type variator in a con-tinuously variable gearbox lacking hydraulic control. The author finds that increasing torque on the driving pulley leads to increased angular velocity ratio between the pulleys. For the pulleys to reach maximum gear ratio position, the spring force pressing the cones against the chain must be greater on the driven pulley compared to the driving pulley. Contact lines between the chain axes and pulley surfaces do not follow circular arcs due to elastic deformation of contact bodies and changes in chain tension force in the contact zone. Midway along the line of contact between the chain and the driving pulley, the distance from the chain to the pulley axis decreases. Similarly, the distance from the chain to the axis of the driven pulley diminishes as chain tension force increases.

FORMALIZATION OF GEOSPATIAL DATA AND DIGITAL INFORMATIONAL MODEL SYNCHRONIZATION PROCEDURE
摘要
The article focuses on applying digital informational models (DIM) in the oil and gas industry of Russia and synchronization methods for data exchange between geographic information systems (GIS) and DIM. Given global digitization trends and limited access to foreign software solutions (SS), Russian oil and gas companies actively employ DIM for infrastructure management. The authors emphasize the importance of implementing DIM for effective control over fields, pipelines, and refining plants while highlighting challenges arising from data inconsistencies among different systems and paying specific attention to selecting tools for implementing GIS based on domestic and open-source solutions. The authors discuss various popular open-source programs such as QGIS, PostgreSQL with PostGIS, GeoServer, OpenLayers, and GRASS GIS as potential candidates for corporate GIS deployment. The paper explores the issue of exchanging data formats between DIM and GIS, focusing on the IFC standard commonly used in construction; examines approaches to synchronizing attribute information between DIM and GIS, including representation examples using an oil pipeline. A proposed mechanism for data synchronization includes modifications to database structures and content updates, ensuring each object receives a unique identifier (UID). This approach simplifies the procedure for forming a unified information space within the company. In conclusion, the relevance of joint usage of DIM and geospatial data in organizations is emphasized, outlining future prospects like building libraries of 3D objects and integrating IoT systems for monitoring infrastructure.

摘要
In the modern world, the number of visually impaired people is growing at a high rate. The social circle of this category of citizens is limited; the ability to use modern gadgets is also reduced. It is necessary to socialize visually impaired people by involving them in the library system work. In these institutions, this category of citizens will be able not only to closely communicate with each other, but also to use the automated capabilities of libraries. The paper describes the main stages of developing a specialized library system for the visually impaired people. The list includes the following implementations: a syntax analyser from the multifunctional software package irbis, an automated book-lending module with various capabilities, a voice assistant module for entering the library system, a news block module with a voice-over function, a graphic editor developed for a specialized system, etc. The work considers the database of a specialized library system, prescribes the database table fields; provides the interface of the administration panel and the tasks implemented by the technology of natural language processing (NLP). The analysis of implementing this system shows its efficiency in terms of accelerating the process of book lending to visually impaired people, obtaining additional information. The automated system is being tested and constantly upgraded.

MODELLING FUNCTIONAL COMPOSITION OF AN AUTOMATED SYSTEM FOR SELECTING MACHINING METHOD AND CUTTING TOOL
摘要
The aim of the study is to develop a functional model of an automated system for selecting a machining method and cutting tool. This system is necessary to improve the quality and speed of developing technological processes for ma-chining parts and reducing production costs while maintaining high product quality. The objective of the study is to conduct functional modelling at the initial stage of developing an automated system to determine the hierarchical structure of the developed automated system and to identify internal relationships. The study uses the methodology of structural analysis, which allows considering the system at different abstraction levels. Within the framework of the structural analysis, the authors apply the IDEF0 functional modelling technology. The novelty of the work lies in bas-ing the functional model on the allowance classification, which allows establishing the relationship between the pa-rameters of the allowance, machining methods and the cutting tool. In developing the model, the authors determine the main modules of the automated system, integration points with the enterprise’s other automated control systems, input and output data. The results of the study can be applied in developing automated systems for technological preparation of production. Further development of the work entails designing implementation algorithms for core functions and establishing databases for allowances, machining methods, and cutting tools. Conclusion states that the constructed functional model in IDEF0 notation allows identifying controlling influences and mechanisms for imple-menting the process of automatic choosing of machining methods and cutting tools. The paper displays interdepend-encies between the processes at one level, determines data flows and logic for executing the system processes.
