Abstract
<jats:p>The problem is considered to increase the reliability of precession elements of meteorological equipment, which play a crucial role in ensuring the accuracy of measurements and the stability of functioning devices during operation. Precession elements are subject to various destabilizing factors, including mechanical loads, friction, wear, temperature fluctuations and changes in material properties, which together lead to a decrease in accuracy characteristics and operational reliability of equipment. In this regard, the application of nanotechnological methods aimed at modifying the structure and properties of materials at the nanoscale is of particular scientific and practical interest. The use of nanotechnology opens up new opportunities for targeted control of the physico-mechanical, tribological and surface characteristics of precession elements, which significantly reduces wear, friction coefficients and increases resistance to external influences. The paper objective is to study the scientific and technical foundations of ensuring the reliability of precession elements of metrological equipment using nanotechnological methods. The following main tasks are identified and analyzed in the paper: study of the reliability of precession elements and systematization of factors affecting their performance; study of the influence of nanotechnological methods on the structure and properties of materials; analysis of surface characteristics and ways of their targeted modification; development of static and frictional mathematical models describing the processes of elements interaction under operating conditions. As a result of the research, mathematical models are proposed and experimental graphs are obtained that make it possible to increase the reliability of precession units of metrological equipment and increase their service life. The implementation of the developed approaches can provide a significant practical effect by increasing the accuracy and reliability of measuring systems used in machine-building enterprises and in other industries where there are increased requirements for the quality of metrological support.</jats:p>
