Abstract

Terms of operation of complex technical systems depend, first of all, on their technical condition, the level of which is determined by the capital class, service life and operating conditions. In turn, operating conditions are characterized by the presence of various types of loads, mechanical stresses caused by operational operations, as well as due to weather and climatic influences. Constant excess of permissible stresses can lead to the destruction of structures. Therefore, the continuous control of mechanical stress in the building is a factor in preventing not only economic losses, but also human casualties. The classification of methods of non-destructive control of mechanical stresses for metallic shutters of hydraulic engineering structures has been developed, a critical analysis of each method has been carried out, positive aspects and drawbacks of each method have been presented, as well as a relative change in residual-magnetized metal sample after application and removal of compressive stresses has been analyzed. The proposed work focuses on the search for new informative parameters based on the study of patterns of change in magnetic properties, on the development of new methods and means of measurement, in particular, with the involvement of several parameters in order to improve the accuracy and reliability of the measurement, significantly expand their capabilities.
