VibTwin provides advanced solutions towards the realization of digital twins with a focus on vibrations. Digital twin engineering encompasses the generation of models representative of physical phenomena. Their qualification is critical for production. Experience shows that verification and validation phases provide a great insight into a system behavior and sensitivity.
VibTwin uses original solutions based on 18 years of experience of Guillaume Vermot des Roches and through its partnership with SDTools for the development and exploitation of the Structural Dynamics Toolbox (SDT). SDT provides scalable solutions for experimental characterization, correlation, updating and sensitivity analysis. It constitutes the foundation of VibTwin expertise including the study of large industrial models with local non-linearities, parametrized model order reduction, junctions study at various scales, damping modelling, non-linear analysis (direct transient, Harmonic Balance method, extended modal methods), test/simulation dialog, hybrid modelling, mesh topology updating, …
Parametrized model order reduction methods are an essential concept that provides the ability to perform large scale Design of Experiments, It opens the path to refined sensitivity analysis, localization of critical features, and even data production for larger scale machine learning training. The ability to finely track system-level behavior evolution with local physical parameters then becomes available, along with validated digital twins.
VibTwin develops and maintains two independent modules for SDT.
- SDT-Contact instruments surface-based coupling functionalities to handle contact properties and models in models.
- SDT-CMT that implements the Component Mode Tuning framework, a model reduction methodology integrating the notion of component assembly. This module provides assembly verification tools and direct component variation assessment at the assembly level.
