The activities of modern machine-building enterprises (organizations) are undergoing significant changes in the current situation. On the one hand, there is a trend towards domestic production (import substitution); on the other hand, there is a growing threat of the appearance of cheap analogues (not always high-quality) of foreign production. Conducting a strategic analysis of the activities of domestic machine-building enterprises allows not only to identify and assess the current position of the enterprise and to identify opportunities and threats in the external environment, but also to thoroughly study the features of the internal environment by identifying strengths and weaknesses. The main purpose of such an analysis is to increase the competitiveness of the Russian machine-building enterprise and ensure the achievement of long-term goals in accordance with a certain strategic direction of development.
The article proposes a scientific and methodological approach to the formation of economic mechanisms for digitalization of high-tech defense-industry enterprises in the Russian Federation, with digital solutions having become a factor in production resilience, fulfillment of state defense orders, technological independence, and cost controllability. It is shown that digitalization should not be reduced to purchasing software, since the economic effect arises only when digital projects are linked with the production program. The authors’ contribution consists in developing a model of economic mechanisms for digitalization, their typology, an integral performance index, and an indicator of digital project priority. An example is given that illustrates the choice between digital dispatching, predictive maintenance, and a digital cooperation contour.
A new approach to estimation of magnetic permeability and magnetoelastic sensitivity of an induction electric motor rotor is proposed. This approach is based on the magnetoelastic effect, which involves changes in the magnetic permeability of the magnetic core depending on the mechanical stresses in it caused by dynamic eccentricity. Calculations of shaft twist angles, mechanical stresses in it, deviations in magnetic permeability, and magnetoelastic sensitivity are performed depending on the rotor shaft eccentricity.
