- ДокументДинамічні характеристики вимірювальних перетворювачів на базі штучних нейронних мереж при застосуванні адаптивного алгоритму(ХНУРЕ, 2019) Фоменко, В. Д.; Пахомова, А. О.Application of adaptive identification method dynamiccharacteristics of measuring instruments by impulse characteristics based on artificial neural networks. At present, artificial neural networks (INS) that are capable of learning from existing data are used to solve many metrological problems. The purpose of this work subsection is the development and application of an adaptive method based on the INS for identifying SIT parameters modeled by dynamic links of the aperiodic and vibrational types according to impulse characteristics.
- ДокументОцінка невизначеності результатів вимірювань кондуктивного паразитного випромінювання методом прямого зчитування(ХНУРЕ, 2019) Штефан, І. Ю.The given work is devoted to the development of a procedure of estimating of uncertainty of measurements. The model equation is recorded, the numerical values of the input values are estimated, the numerical value of the measured value is calculated, the standard uncertainties of the input quantities, the sensitivity coefficients, the total standard uncertainty, and the expanded uncertainty are estimated. The uncertainty budget is given.
- ДокументРозробка метрологічного забезпечення контролю якості продукції машинобудування(ХНУРЕ, 2019) Юношев, Д. Є.Metrological control of smooth cylindrical joints has been improved. A comparative analysis of the existing normative base on the tolerances and landing of smooth cylindrical joints, calibre-scraps, calibre-plugs, methods of calculating the planting parameters, methods of statistical processing of measurement results is made. The proposed method of calculating calibers for controlling external elements of parts, providing interchangeability and quality of parts. The method of choice of universal means of measuring equipment for control of parameters of smooth cylindrical joints is offered.
- ДокументЯкість, стандартизація та взаємозамінність машинобудівної продукції(ХНУРЕ, 2019) Мартинов, М. А.This work is aimed at improving the standardization system for transitional fits of smooth cylindrical joints, as well as at improving metrological support of measurements and control of linear parameters of smooth cylindrical joints. The object of study - the accuracy characteristics of the mates of parts - smooth cylindrical joints with transitional fit. To achieve this goal, a probabilistic-statistical method for calculating the parameters of transitional landings is proposed, which ensures interchangeability and quality of parts. A technique is proposed for selecting universal measuring instruments for monitoring the parameters of smooth cylindrical joints.
- ДокументРозробка метрологічного забезпечення калібрувань засобів вимірювання геометричних розмірів(ХНУРЕ, 2019) Пахомова, А. О.; Фоменко, В. Д.The system of accounting and documenting the results of the verification of the suitability of measuring instruments for operation is proposed. A local validation scheme has been developed. The method of carrying out calibration of measuring instruments of geometric quantities, which provide the correct and unified procedure of calibration, is developed. Methods of comparative analysis of existing verification methods, national and international normative base in the field of metrological support of measuring instruments of geometric quantities, methods of statistical processing of measurement results are used.
