Metrological support of initial accuracy of roughness measurement methods based on different physical principles

This article describes the research of a new generation of means of measuring geometric parameters of surface texture based on various physical principles in order to identify their capabilities (subject to known limitations to them), reproduce and transmit using a set of measures of units of length in the field of measurements of geometric parameters of surface texture with the accuracy required for nanotechnology and other high-tech industries.

Based on the results of research on the measuring capabilities of texture parameters measuring tools involved in the experiment, based on various physical principles, it was concluded that it was permissible to use these tools as reference standards for accuracy when reproducing a unit of length in the field of measurements of geometric parameters of surface texture.

Keywords: surface texture, measurements, coherent correlating interferometers.

Neural network algorithm for diagnosing the technical condition of a strain gauge pressure sensor

In the course of studying the existing algorithms for diagnosing the technical condition of pressure transducers, it was found that their implementation requires either a change in the design of the sensor, or the basis of the production process, which is economically unprofitable. Therefore, this study was faced with the task of developing an algorithm for diagnosing a technical condition using artificial neural networks, which makes it possible to increase the reliability of the operation of tensometric pressure transducers.

The use of an artificial neural network makes it possible to assess the quality of the functioning of the measuring unit, as well as to identify the occurrence of a sensor failure during its operation.

The problem of diagnostics in this work is solved in two formulations: as an approximation problem (RBF and FITNET networks) and classification (PNN and PATTERNNET network) data. It was found that if an accurate assessment of the development of a malfunction is required, both types of networks (RBF and FITNET networks) can be used, since the approximation problem gives similar results in both cases, and if there is no need to numerically estimate the degradation of the sensor characteristics, it is better to use a model based on PNN network tools.

Keywords: diagnostic algorithm, strain gauge pressure sensor, artificial neural network, approximation, classification, technical diagnostics.

Metrological assurance of additive technologies in the interests of industry development

An approach to the formation of a unified system of tolerances and fits of surfaces obtained by layer-by-layer build-up technologies is proposed. The results of comparing the dimensions of complex-profile parts made according to the same model, injection molding and 3D-printing are presented. The information capacity of measuring instruments for solving problems in the field of metrological assurance of additive technologies is considered.

Keywords: additive technologies, metrological assurance, tolerances, product life cycle, information capacity, accuracy class, interchangeability.

A new device for measuring the impact active force, structurally similar to magnetoelastic transducers

The previously discovered properties of ferromagnets during their dynamic deformation made it possible to use a magnetoelastic type converter (CBM) to measure active dynamic loads, including shock, of high intensity. New works have defined procedures for stabilizing the operating mode parameters and determining the sensitivity of such devices, to develop a dynamic calibration technique for them.

Keywords: sensor structurally similar to CBM, dynamic calibration, load characteristic, measurement of active dynamic forces.

Investigation of the behavior of a ferromagnet under dynamic deformation by the example of invar 44NXTU

It has been experimentally found that during the dynamic deformation of a ferromagnet, a shift in the dynamic dependence of Um(Ip) is observed by a certain amount, this may indicate the presence of a new effect peculiar to ferromagnets, consisting in the generation of eddy current fields in a ferromagnet during its dynamic deformation. It has been suggested about the possible nature of the new effect. It has been experimentally proved that magneto-dynamic stabilization of a magnetic core is possible, and there is a way to quantify the relationship between the change in the magnetic state of a ferromagnet and the dynamic effect on it.

Keywords: ferromagnet, dynamic shock load, eddy current polarization.
