Project Description

One of the key technologies used in industry and academia to analyse and understand dynamic structures is modal analysis. This PhD project, based in the Dynamics Research Group at The University of Sheffield, aims to extend and enhance our current techniques through machine learning.

By considering statistical machine learning methods, the objectives of this project are to answer questions like:

• Have we collected enough data to confidently say something about a structure?

• Is noise in our test causing us to misidentify the behaviour of a structure?

• How many degrees of freedom do we have evidence for in the data?

• Can we automate the selection of a model for our system?

As well as being a technically interesting challenge, by developing tools to answer these questions, this project will provide methods for industrial practitioners to make confident decisions about the design and operation of engineering systems. Through form uncertainty quantification and management engineers can build more efficient structures and operate them with a higher degree of confidence. This project will provide an opportunity to explore how recent advances in machine learning can impact the way we address a traditional engineering problem.

About the Dynamics Research Group

The Dynamics Research Group (DRG) based in the Mechanical Engineering department at The University of Sheffield is a world leading research group focussed on nonlinear dynamics, structural health monitoring, vibration control, and smart materials and structures. As well as having 70+ members undertaking research in the group, there is access to unique facilities including the £12m Laboratory for Verification & Validation with capability to test dynamic structures under realistic environmental conditions. This provides an exciting and vibrant environment in which to perform state-of-the-art research.
