Methods for Design of Virtual Twin of a Dynamic System
Kšica, Filip ; Novotný, Tomáš (referee) ; Holub, Michal (referee) ; Hadaš, Zdeněk (advisor)
Over the last decade, digital twins and cyber-physical systems have been slowly developed from mere theoretical concepts to potent industrial applications in a large spectrum of areas, however, ambiguous understanding of the fundamentals significantly complicates the process of finding a general methodology necessary for their successful implementation. Therefore, one of the main goals of this thesis is a systematic study of these concepts and their main parts, followed by formulating a methodology that could lead to successful and effective industrial applications in the context of current projects. The key part in this effort falls to computational modelling and dynamic reduction of complex mechanical systems that comprise the digital part of a digital twin, including but not limited to the main structure but also sensing systems. These sensing systems serve as cyber-physical systems that fulfill the role of interactive links between the individual parts of a digital twin and are introduced in the last part of this thesis in the context of manufacturing industry, airspace, and railway industry, where they are used not only for condition and operational monitoring, but also provide large amount of accurate real-time data for structure health monitoring and predictive maintenance purposes.
