Projekt
Robust model updating of Digital Twins under consideration of uncertainties (C04)
Subject Area
Applied Mechanics, Statics and Dynamics
Term
since 2021
Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 434502799
Robust model updating connects the Digital Twin with the associated real structure by adjusting the simulation model to minimise deviations between measurement and simulation data. It is essential for the planned SFB to adapt the Digital Twin to long-term changes. In SP C04, a method for robust model updating of the Digital Twin is to be investigated. For the first funding period, it is planned to formulate the objective function of the model updating process based on modal quantities (natural frequencies and mode shapes). The update shall be carried out by applying a global multi-objective optimisation under consideration of measurement and model uncertainties.
