Monitoring of an engineering structure in the process of its operation in a corrosive environment

Abstract

The functioning of engineering structures that perform critical technological operations isimpossible without monitoring its deformation state. The fundamental engineering problem of thisstudy is the development of an automated system for monitoring deformation processes in a structuresubject to severe corrosion, as well as the adaptation of this system to the aggressive effects of theexternal environment (exposure to salt brines and aerosols, operation at low temperatures). Theengineering structure is a large-scale metal construction for lifting and unloading potash ore from amine shaft. A mathematical model has been created for this structure, considering the main weight,size and stiffness characteristics. Installation locations and sensors parameters were determined onthe basis of numerical experiments. The systems of sensors adapted to the conditions of a corrosiveenvironment have been developed to control quasi-static, vibrational and dynamic processes ondifferent time scales. Examples of readings of various types of sensors are given to illustrate theresponse of the structure to natural, man-made and technological processes.
