Digital twins creation based on discrete modelling of non-destructive evaluation objects

Abstract

Nowadays, the implementation of digital industrial technologies for maximal industrial processes automation and unmanned technologies creation is the main direction of technological development in the key of Industry 4.0 and NDE 4.0 paradigms. Service-oriented approach is proposed for the implementation of digital non-destructive evaluation as an effective solution for obtaining, processing and storing data and testing results. The model of industrial radiography laboratory simulator is considered, discrete models of digital twin objects are built when obtaining an image, for which the basic statements and tools of set theory are used. Examples illustrating the correspondence of digital twins’ mathematical models to their graphical analogues as well as the image generated on the detector are presented. The subject of extending CAD systems tools in the context of practical design of digital twins geometric image is considered. It is noted that virtualization of such a complex technical object as industrial radiography laboratory allows to check feasibility of technical solutions and engineering hypotheses with regard to real industrial conditions and needs in a short period of time and with minimum costs, thus providing, variability in implementation of process steps, and increasing the number of trained qualified specialists in radiation kind of non-destructive evaluation.
