Time-varying vibro-acoustic digital twins towards a sustainable society.

The current European energy crisis has re-established the importance of accelerating our transition towards a more sustainable society and industry. The sustainable design and monitoring of vehicles and machines is an important contributor to this transition. To improve sustainability, a delicate balance between the conflicting criteria of health, profitability and environment needs to be found. One of the most important health considerations towards this goal is noise pollution.  

The recently emerged digital twin paradigm has the potential to help us find this balance. A digital twin is a digital copy of a physical asset that behaves the same as the physical asset. Thus, by using sensor data from the physical asset, it can make design/control/maintenance decisions. In the context of vibro-acoustics initial digital twin applications show great potential using the underlying assumption that the physics are time-invariant. However, many vibro-acoustic systems instead show time-varying behavior.

Therefore, the goal of this project is to assess how the inclusion of time-varying behavior in the digital twin can improve performance towards sustainability, by looking at time-varying behavior at different time scales. In the project novel physics-based models, model order reduction techniques and digital twin formulations will be developed, looking at several use cases to demonstrate the potential of time-varying digital twins to tackle the sustainability challenges of the future.
