Determination of characteristics of the measuring complex when using non-standard metrological equipment

Abstract

Purpose. Develop a comprehensive methodology for determining the metrological characteristics of measuring complexes, which include non-standard metrological equipment, which allows for an objective assessment of new technical solutions that will ensure their compliance with national and industry standards, and will contribute to the adaptation of production processes to modernization and unification. The methods. To achieve the goal of the work, quantitative methods were used to analyze the quality indicators of production equipment, process and interpret information regarding the justification of requirements for ensuring compliance between the properties of new technical solutions used in production and the conditions of their use. Findings. Methods for checking the quality indicators of production equipment at different stages of the life cycle have been established and substantiated, which allows them to be confirmed not according to all parameters. An effective model and program for calculating the predicted quality indicators of design and construction works during the modernization of production equipment with the use of non-standard metrological support have been proposed, which allows establishing their compliance with the requirements of the technical task, technical conditions and standards of the state measurement system, and determining the necessary metrological characteristics. The originality. A methodology has been developed for determining the metrological characteristics of measuring complexes with non-standard equipment, which made it possible to establish dependencies between structural parameters and measurement accuracy. A correlation relationship was identified between statistical indicators and the reliability of results; approaches to adaptive metrological expertise were advanced, and quality control methods were improved through the use of strain-gauge measurements and digital data analysis. Methodologically, the system for evaluating the effectiveness of design and technological solutions was enhanced by integrating strain-gauge measurements, statistical analysis, and digital data processing, providing a foundation for creating universal models of metrological support for modernized industrial equipment. Practical implementation. The presented results allow to assess the quality of new technical solutions and accordingly to monitor and adjust the production process in order to maintain a given level of quality according to controlled parameters. Statistical quality indicators were obtained, which confirm the effectiveness of the proposed design and technological solutions.
